Henry Luhrs’ basic philosophy was to emulate
the late Henry Ford in building an inexpensive
boat for the average man, thus enabling him
to enjoy the luxury of boating. He was both
designer and engineer, creating innovative and
progressive new models. He designed the change
in the line of the bow from straight to curved, at
a time when all boats were being built with the
straight, square effect. It is believed he was also
the first designer-builder to popularize a small
boat with a flybridge.
THE SILVERTON STORY
SILVERTON YACHT OWNER
AND FOUNDER
JOHN LUHRS
WARREN LUHRS
________________
Hailing from East Orange, New Jersey, John
and Warren Luhrs’ ancestry goes back to their
great-grandfather, Henry, who helped pioneer
the development of railroading and clipper ships
in America, and to their great-uncle, John, who
helped build the famous St. Petersburg-to-Moscow railroad for Russian Czar, Alexander II.
In 1960, Henry Luhrs acquired the Ulrichsen
Boat Company, located in Marlboro, New
Jersey. It was here, too, that the Luhrs Alura
Fiberglass Division was located. In 1965,
Henry sold his company to Bangor Aroostok
Railroad, which was to become the recreational
conglomerate, Bangor-Punta. It was also during
this period that the Silverton Company, in Toms
River, New Jersey, was purchased by his sons,
John and Warren Luhrs.
Henry Luhrs owned shares in twenty-two different ocean-going vessels - barques, brigs and
schooners - and was the principal owner of the
barque, Sophia R. Luhrs, named after his wife.
He was also a partner with Albert Sprout, who
managed a shipyard in Melbridge, Maine, where
the Sophia R. Luhrs was built.
Today John and Warren Luhrs own Silverton
Marine Corporation, Hunter Marine Corporation, Mainship Motor Yachts Corporation, and
Luhrs Fishing Boats Corporation, known as the
“Luhrs Marine Group”.
The Luhrs’ family sea tradition was carried on
during the great Depression by John and Warren
Luhrs’ father, Henry, who worked at a small boat
manufacturer in Morgan, New Jersey and later
started his own company. When war broke out
in Europe, the United States Coast Guard asked
Henry Luhrs to repair their boats and install ice
sheathing on their bows.
In January, 1996, John and Warren transferred
a portion of the Luhrs Group to its employees,
through an Employee Stock Ownership Program,
ensuring a personal interest in the construction
of your Silverton yacht.
After World War II, Henry built 27-foot fishing
boats and in 1948, he began to construct custom-built pleasure craft. He then turned to skiffs
and in 1952, incorporated as “Henry Luhrs Sea
Skiffs”. He constructed lap strake sea skiffs using assembly-line techniques. Henry personally
“shook down” his prototypes with family trips
up the Hudson River to Lake Champlain.

Accident Report is included with this Owner’s
Manual. You can obtain more copies of the report by calling the United States Coast Guard
Boating Safety Hotline at 1-800-368-5647.
You are required to file an accident report with
the United States Coast Guard within forty-eight
(48) hours after the occurrence of an accident
resulting in any one of the following:
• Loss of life.
• A person disappears from a vessel un der circumstances that indicate the possibility of death or injury.
• Personal injury requiring medical treatment beyond first aid.
• Damage to the vessel or damage to property.*
• Complete loss of the vessel.
* State statutes determine whether you must file
an accident report in this case. An accident report
must be filed if the damage exceeds a threshold
dollar value as established by the state in which
the accident occurred. In most states, the threshold is $100.00 to $200.00. Contact the United
States Coast Guard Boating Safety Hotline to
verify the threshold for a particular state.

BOATING SAFETY
Minimum Recommended
Safety Equipment
________________
Silverton believes your safety aboard your yacht,
whether cruising or moored at your dock, is
extremely important. A yacht operated in a safe
manner will provide you, your passengers, and
other boaters many pleasurable hours of cruising and piece of mind. This section discusses
the potential hazards that may be associated
with boating for your awareness so they may be
avoided, if possible. Be certain to read and have
a thorough understanding of this section.
Silverton recommends completing a safe boating
course if you are new to boating. Even if you
are an experienced boater, you should consider
enrolling in one of these courses as they will
provide you with updated information that will
prove to be valuable and enhance your cruising
pleasure. Your local United States Coast Guard
Axillary and United States Power Squadrons
offer comprehensive safe boating classes several times a year. You may contact them for a
course schedule in your area or the Boat/U.S.
Foundation at 1-800-336-BOAT, or in Virginia,
at 1-800-245-BOAT.
Safety Equipment
Important: Federal Law requires you provide
and maintain certain safety equipment on your
yacht. As the yacht owner, you are responsible
for providing all required safety equipment.
Consult the United States Coast Guard and your
state and local regulations to ensure your yacht
is in complete compliance with all requirements
concerning safety equipment on board. Additional safety equipment may be recommended
for your safety and the safety of your passengers.
Be aware of its availability and specific use.
•
Required life saving equipment, includ-ing
life vests and throwable devices.
•
Required fire extinguishing equipment.
•
Required Visual Distress Signal Devices
(Flares).
•
First Aid Kit.
•
Emergency Position Indicating Radio Beam
(EPIRB).
•
Manual bailing device.
•
Anchor with sufficient line and/or chain.
•
Flashlight with fully charged batteries.
•
Binoculars.
•
VHF Radio.
•
Navigational charts for your cruising areas.
•
Fog Bell.
Personal Flotation Devices (PFD’s)
United States Coast Guard regulations require
you to have at least one (1) approved Type I,
Type II, or Type III Personal Flotation Device
(PFD) for each person on board. The PFD’s
must be of suitable size for each person aboard
and must be maintained in serviceable condition
and readily accessible. A minimum of three (3)
PFD’s (two wearable and one throwable) are
required, regardless of the number of persons
on board. Each of these Personal Flotation de33
Note: United States Coast Guard regulations for
the number and type of PFD’s are the minimum
required. Silverton recommends exceeding the
minimum requirements for your safety and the
safety of your passengers.
vices, commonly known as “Life Jackets”, are
described as follows:
Type I (Wearable): This off-shore PFD has
the greatest buoyancy. It is most effective for
all waters where rescue may be delayed. Its
design allows for turning most unconscious
persons in the water from a face down position
to a face up position, assisting in the prevention
of drowning.
Fire Extinguishing Equipment
As a yacht owner, you are responsible to maintain
a minimum number and type of portable fire extinguishers on board. All fire extinguishers must
be approved by the United States Coast Guard
and be readily accessible and in serviceable condition. United States Coast Guard classification
includes foam, carbon dioxide and chemical fire
extinguishing materials, which are described in
detail in the Portable Fire Extinguisher System
Section of this Owner’s Manual. Be certain to
read and have a thorough understanding of the
portable fire extinguishing equipment. United
States Coast Guard minimum requirements for
portable fire extinguishers maintained aboard
your yacht are as follows:
Type II (Wearable): This near-shore PFD
provides less buoyancy than a Type I PFD. It is
intended for use in calm, inland waters or waters where there is a greater chance of a quick
rescue. It turns its wearer to a face up position
as does the Type I PFD, but the turning action is
not as pronounced. A Type II PFD may not turn
as many persons to a face up position under the
same conditions as would a Type I PFD.
Type III (Wearable): Classified as a flotation
aid, the Type III PFD permits the wearer to place
himself in a vertical or face up position, but it
will not do it automatically as would a Type I
or Type II PFD. The Type III PFD has the same
minimum buoyancy as a Type II PFD, but it has
little, or no, turning ability. It is intended for use
in calm, inland waters where immediate rescue
is probable. The Type III PFD is used most
often by people participating in water sports,
as it is generally the most comfortable type for
continuous wear.
• Yachts longer than 26 feet and shorter than
40 feet: Two (2) Type B-I or at least one (1) Type
B-II portable, hand-held fire extinguisher. If your
yacht has a fixed fire extinguishing system approved by the United States Coast Guard, one (1)
Type B-I portable fire extinguisher is required.
• Yachts longer than 40 feet and shorter than
65 feet: Three (3) Type B-I or one (1) Type B-I
and one (1) Type B-II portable, hand held fire
extinguishers. If your yacht has a fixed fire extinguishing system approved by the United States
Coast Guard, two (2) type B-I or one (1) Type
B-II portable fire extinguisher is required.
Type IV (Throwable): United States Coast
Guard regulations require at least one (1) throwable Type IV PFD to be on board, regardless of
the number of passengers. The Type IV PFD
is not intended to be worn; it is intended to be
thrown to a person who has fallen overboard and
is conscious. The Type IV PFD is held by the
user until rescued. The most common examples
of Type IV PFD’s are buoyant cushions or ring
buoys which are required to be immediately
available for use and in serviceable condition.
Note: United States Coast Guard regulations are
the minimum requirements. Silverton recommends exceeding the minimum requirements
for your safety.
34
Fire Prevention
- NEVER leave the craft unattended when
cooking and/or heating appliances are in
use.
Fire can not only damage or destroy your new
yacht, it can also be deadly. However, with a
little effort on your part, fire prevention and fire
safety is a very attainable goal.
- NEVER modify any of your yacht’s systems
(especially electrical, fuel, and gas).
As owner of your yacht, it is your responsibility to:
- NEVER fill any fuel tank or replace gas
bottles when machinery is running or when
cooking or heating appliances are in use.
• Have fire fighting equipment checked at regular
intervals located on the equipment.
- NEVER smoke while handling fuel or gas.
• Replace fire fighting equipment, if expired or
discharged, by devices of identical or greater fire
fighting capacity.
Other good ways to prevent fire aboard your
yacht is to keep the bilge areas clean and to check
for fuel and gas vapors at regular intervals, and
not to fit free hanging curtains or other fabrics
in the vicinity of or above cookers or other open
flame devices.
• Inform members of the crew about:
- the location and operation of fire fighting
equipment.
- the location of discharge openings into the
engine space.
- the location of escape hatches.
Also combustible material should not be stored
in the engine compartment. If non combustible
materials are stowed in the engine space they
shall be secured against falling into machinery
and shall cause no obstruction to access in or
from the space.
• Ensure that fire fighting equipment is readily
accessible when the craft is occupied.
Fire prevention is something
that you as the yacht owner are responsible for.
Too much fire prevention is not possible. This
is an area that is unfortunately often overlooked
by boat owners. However, as long as this area is
an important part of your boating safety preparation, you can help to make your journeys safer
for not only for you, but your crew and family
as well.
Some things should NEVER be done in order
to help prevent fire aboard your yacht.
- NEVER obstruct passage ways to exits and
hatches.
- NEVER obstruct safety controls, e.g. fuel valves,
gas valves, or switches of the electrical
system.
- NEVER obstruct portable fire extinguishers
stowed in lockers.
- NEVER use gas lights in your yacht.

Visual Distress Signal Devices
Visual Distress Signals
with packaging which children, but not adults,
will find difficult to open.
The United States Coast Guard requires all
boats operating on the coastal waters of the
United States to maintain visual distress signal
equipment (flares) on board. Coastal waters are
defined as all waters, except rivers, streams,
and inland lakes. The Great Lakes and any
river mouth greater than two (2) miles wide
are considered coastal waters. All boats owned
in the United States and operating on the high
seas are required to carry visual distress signal
equipment on board.
Sound Signaling Devices
The United States Coast Guard requires all boats
over 16 feet in length to have a device that is
capable of producing a sound signal when conditions require. Boats greater than 26 feet and less
than 39 feet 4 inches, must have a sound signalling device that is capable of producing a four (4)
second blast, which can be heard at least one-half
mile away. The device may be either hand held
or power operated. Boats greater than 39 feet 4
inches must have in addition to the above sound
signaling device, a whistle and a bell, which
must meet or exceed the requirements of the
Inland Navigational Rules Act of 1980.
All visual distress signal devices are required
to be maintained in serviceable condition and
stowed in a readily accessible location. Equipment displaying a useful service life date must
be within the specified usage date shown. Both
pyrotechnic and non-pyrotechnic equipment
must be United States Coast Guard approved.
Refer to the United States Coast Guard publication “Navigational Rules, International-Inland”
for specific requirements of sound signaling
devices.
Pyrotechnic visual distress signal devices and
their associated equipment include the following:
•
Red Flares - Hand held or aerial.
•
Orange Smoke - Hand held or floating.
•
Launchers for aerial red meteors or parachute flares.
Navigation Lights
The United States Coast Guard requires all boats
that are operated during the hours of darkness
or when visibility is impaired, be equipped with
navigation lights that are illuminated. Observe
all rules of navigation when meeting or passing
another vessel. DO NOT operate your yacht at
high speeds during night operation or when visibility is impaired. A good rule to follow is to
NEVER operate your yacht at a greater speed
than that which would prevent you from stopping within the distance of your visibility.
Always use common sense and good judgement when operating your yacht at night or
during restricted visibility.
Non-pyrotechnic visual distress signal devices
include the following:
•
Orange Distress Flag.
•
Dye Markers.
•
Electric Flashing Distress Light.
No single visual distress signal device is perfect for all conditions or purposes. Silverton
recommends carrying various types of devices
as described above. Careful selection and the
proper stowage of visual distress signal equipment is extremely important. If young children
are frequently aboard, you should select devices
Refer to the United States Coast Guard publication “Navigational Rules, International-Inland”
for specific navigational lighting requirements.

Additional Safety Equipment
Navigation
Rules of the Road
You should consider having additional equipment on board your yacht to help make your
cruising experience safer and more enjoyable.
Some examples of this additional equipment
are as follows:
Navigating your yacht is much the same as
driving an automobile. Operating either one
responsibly means complying with a set of rules
intended to prevent accidents. Just as you assume other automobile drivers know the rules of
the road and expect them to abide by them, other
boaters assume the same of you. As a responsible
yachtsman, you must comply with the “Rules of
the Road”; the marine traffic laws enforced by
the United States Coast Guard. There are two (2)
sets of rules: The United States Inland Navigational Rules and the International Rules. The
United States Inland Navigational rules apply to
all vessels operated within the demarcation lines
separating inland and international waters. The
United States Coast Guard publishes the “Rules
of the Road” in its publication “Navigational
Rules, International-Inland”. You can obtain a
copy of this publication from your local United
States Coast Guard Unit or the United States
Coast Guard Headquarters, 1300 “E” Street NW,

• Always adhere to navigational rules to avoid
Other helpful publications available from the
United States Coast Guard include, “Aids to
Navigation” (Pamphlet #123), which explains
the significance of various lights and buoys;

restrict its maneuverability).
Basic Rules of Safe Boating
• Drugs and/or Alcohol and Boating DO NOT
Mix. Drugs and/or alcohol decrease your reaction time, impair your judgement, and inhibit
your ability to safely operate your yacht. As a
responsible boater, you will refrain from using
drugs or alcohol (singly or combined) while you
are operating your yacht. Operation of motorized
vessels while under the influence of drugs and/or
alcohol carries a severe penalty.
Vessel With Restricted Maneuverability
Any vessel, due to it size, draft, or cargo, that is
restricted in its ability to maneuver in a certain
waterway.
Underway
Any vessel not anchored, not made fast to shore
and not aground, whether or not it is under power
or sail.

meet or exceed regulatory standards and it
should be noticeable, easily accessible, and in
proper operating condition. Your passengers
should know where this equipment is located
and how to use it.
• Instruct at least one other person on board
your yacht in its basic operating procedure. This
person can take over the operation of your yacht
if you unexpectedly become unable to do so.

your yacht. Be certain you know the capacity
of the fuel tank(s) and the amount of fuel you
consume when operating at your normal cruising
speeds. Read and have a thorough understanding of the Fuel System Section of this Owner’s
Manual. It contains valuable information and
warnings that, if strictly adhered to, will enhance
your yachting pleasure and safety.
• Always maintain a good lookout. Keep away
from swimmers, divers, and water-skiers. They
should display a flag when engaged in these
types of water sports, but DO NOT rely upon
it; if you suspect that type of activity, it is best
to avoid that area, if possible.
• Check the weather forecast before getting underway. DO NOT venture out if the weather is, or
is expected to be, threatening. While underway,
always be cognizant of changing weather conditions by frequently checking the local forecast.

Voluntary Safety Inspections
The United States Coast Guard Axillary and
boating officials in many states offer courtesy
safety inspections of your yacht at no charge to
you. They will examine your yacht for compliance with all safety standards and required safety
equipment. You may voluntarily consent to one
of these inspections and you are given sufficient
time to make necessary corrections without fear
of prosecution for any discrepancies found.
Contact your local United States Coast Guard
Axillary or appropriate state agency for details
concerning these courtesy safety inspections.
Carbon Monoxide Safety
Your 453 Motor Yacht is powered by diesel
engines. The levels of Carbon Monoxide gasses produced by diesel engines are a very small
percentage of those produced by gasoline powered engines. However, many vessels around
you are powered with gasoline and the risk of
CO gasses entering your boat are very real. The
following section on Carbon Monoxide Safety
was written for gasoline powered boats but the
information still applies. Moreover, all of this
information is important to know as a responsible boat owner.
Carbon Monoxide Gas (CO)
is colorless, odorless and tasteless. It is highly
poisonous, endangering lives even at very low
levels of concentration. Mild exposure causes
headaches and fatigue, often resembling “flulike” symptoms. Medium exposure causes
severe headaches, drowsiness, nausea and
rapid heart rate. Extreme exposure results in
unconsciousness, convulsions, cardiorespiratory
failure and death. If Carbon Monoxide Gas (CO)
is detected in your yacht, immediately contact
a qualified technician to locate and repair the
source of the poisonous gas. DO NOT enter
your yacht until repairs have been made and
the Carbon Monoxide Gas (CO) is lowered to
an acceptable level.
40
Carbon Monoxide Gas (CO) inhaled into the
lungs combines with the blood to reduce the
ability to carry oxygen. Reducing the amount
of oxygen to the body tissue results in death of
the tissue. The presence of Carbon Monoxide
Gas (CO) requires the yacht operator’s special
and immediate attention. Carbon Monoxide
Gas (CO) in high concentrations is fatal within
minutes. The effects of lower concentrations
are cumulative and can be as lethal as high
concentrations.
The symptoms of excessive exposure to Carbon
Monoxide Gas (CO) concentrations may include
watery and itchy eyes, throbbing temples, ringing in the ears, inattentiveness, headache, nausea, dizziness and drowsiness.
Certain health problems, such as lung disorders
or heart problems and age will increase the effects of Carbon Monoxide Gas (CO) as does
consuming alcohol or high concentrations of
tobacco smoke.
Many variables affect Carbon Monoxide Gas
(CO) accumulation. Among these are the following:
•
Yacht layout and configuration.
•
Location of hatch, window, door, and ventilation openings.
•
Location of structures and other boats.
•
Wind direction.
•
Vessel speed.
This Owner’s Manual cannot identify or describe
every possible variable or combination of variables that may affect the accumulation of Carbon
Monoxide Gas (CO). The yacht operator must
remain aware at all times of the possibility and
prevention of its accumulation and the appropriate action to be taken if it is detected.
Be certain to read and have a thorough under-
standing of the Carbon Monoxide (CO) Detector System Section of this Owner’s Manual. It
contains valuable information and warnings for
you and your passengers safety.
Protective weather coverings
are in place, engine or generator exhaust from
your yacht, while docked, at anchor, drifting or
underway can cause excessive accumulation of
Carbon Monoxide Gas (CO) within the cabin
and cockpit areas of your yacht. Always provide
adequate ventilation when the weather coverings
are in place and either the engine or the generator are running.
The following illustrations show how Carbon
Monoxide Gas (CO) can accumulate in your
yacht while either at your dock or underway.
Become familiar with these examples and their
precautions to prevent exposure to this poisonous gas.
Blocked hull exhaust outlets
near a pier, dock, seawall, bulkhead or any other
structure can cause excessive accumulation of
Carbon Monoxide Gas (CO) within the cabin
areas of your yacht. Be certain hull exhaust
outlets are not blocked in any way.
Engine or generator exhaust
from your yacht while underway at a slow
speed can cause excessive accumulation of
Carbon Monoxide Gas (CO) within the cabin
and cockpit areas of your yacht. A tail wind can
increase the accumulation. This is often referred
to as the “Stationwagon Effect”. Always provide
adequate ventilation or increase your speed, if
possible.
Engine and generator exhaust
from other vessels alongside your yacht, while
docked or anchored, can cause excessive accumulation of Carbon Monoxide Gas (CO) within
the cabin and cockpit areas of your yacht. Be
alert for exhaust from other vessels.
41
EMERGENCY SITUATIONS
Engine or generator exhaust
from your yacht while underway and operating with a high bow angle can cause excessive
accumulation of Carbon Monoxide Gas (CO)
within the cabin and cockpit areas of your yacht.
Always provide adequate ventilation and redistribute the load to lower the bow angle.
Swamped or Capsized Yacht
If your yacht becomes swamped or capsizes,
immediately put on a PFD and set off a visual
distress signal. A swamped or capsized yacht
will normally stay afloat. DO NOT leave your
yacht or attempt to swim to shore, except under
extreme conditions, such as fire or explosion. A
capsized yacht is much easier to see by a potential rescuer than a person swimming, resulting
in a greater chance of rescue. If you attempt to
swim to safety, the shore may be farther away
than it appears and you may tire and not be able
to reach your destination, resulting in possible
drowning.
Fuel Safety
Hypothermia
If a person falls overboard or is in the water due
to a swamped or capsized yacht, hypothermia
may be an immediate concern. Hypothermia
exists when the body loses heat faster than it can
replace it. If not rescued within a short period
of time, the person will become exhausted and
likely drown. In general, the colder the water,
the shorter the time for survival. If the person
is wearing a PFD, it will greatly increase his
survival time as they act as an insulator and
will also keep the person afloat even if he is
unconscious.
Diesel Fuel is extremely flammable.
Proper handling is necessary to provide for the
safety of you and your yacht.
DO NOT smoke while fueling.
Make sure that all accessories, both engines
and generator, are turned off before beginning
to fuel your yacht.
Collision
When fueling your yacht in warm weather,
allow for expansion of the fuel and do not top off
the fuel tanks. The tanks may overflow when the
fuel expands after being pumped out from cool,
underground tanks or when the air temperature
is cool, such as early morning or evening.
If a collision occurs, the following procedure
should be strictly adhered to:
• Be certain all passengers put on their PFD.
If a passenger is unable to put on his own PFD
due to a disabling injury, assist him.
Always handle fuel with care.
Never store portable fuel containers aboard
your yacht.
• Examine all persons on board for any injuries
and administer first aid, if necessary.
42
Silverton recommends using a commercial
towing service for your safety and to decrease
the potential for additional damage to your
yacht as a result of removing it from the underwater obstruction.
• If your yacht has a VHF radio, contact the
United States Coast Guard and any other potential rescue vessel and advise of your situation
and location. VHF radio contact may be made
on Channel 16 and Citizen’s Band (CB) radio
contact may be made on Channel 22.
NEVER attach a tow line to
a deck cleat or anchor windlass. The cleat or
windlass may pull free from the deck and cause
serious personal injury or property damage.
• Inspect your yacht to determine the extent of
damage and its potential for sinking.
• Prepare to assist the other craft and its passengers, if possible.
Hazardous Weather Conditions
• If the collision resulted in penetration of your
hull, prepare to quickly plug the fracture with a
spare life jacket or bunk cushion once the vessels are separated.
Storms
Storms rarely appear without some advance
warning. Check the local weather forecast before
you leave port, but be aware that weather conditions can change rapidly. If you have a VHF
radio, listen to the continuous weather reports
issued by the National Weather Service. If you
have a portable radio, keep it tuned to a station
that broadcasts frequent weather reports. If you
are tuned to an AM frequency, listen for static;
it often means an electrical storm is approaching. Many boating clubs fly weather signals in
the form of flags or lights. Learn to recognize
these signals.
• Before plugging the fracture, trim the yacht
to place the damaged section above the water
level.
• Remain with your yacht until assistance arrives.
Running Aground
• If your yacht runs aground, examine everyone on board for injuries and render first aid, if
necessary.
Your surroundings can also be a good indicator of changing weather conditions. Watch for
changes in wind direction or cloud formations.
There is no substitute for a good understanding
of typical weather conditions and what to do
when it takes a turn for the worse.
• Examine your yacht for damage to the hull
and running gear. If no serious damage is noted,
attempt to free the yacht by shifting weight to
the bow to raise the stern and then reverse the
engines and back out of the shallow water into
deeper water.
Fog
• If towing is necessary, DO NOT attach the tow
line to the deck cleats. They are not designed to
take the full load of the yacht under pressure.
Fog is the result of either cold air passing over
a warm earth surface or warm air passing over a
cold earth surface. You can judge the likelihood
of fog formation by periodically measuring the
air temperature and the Dew Point temperature
43
Fire
(temperature at which moisture in the air will develop), which is given during a normal weather
forecast. If the difference between these two
temperatures is small, fog is likely to develope.
Always remember the following guidelines if
you encounter fog conditions:
Fire aboard your yacht is always serious, but
it can usually be brought under control if you
are prepared and act quickly. Fire extinguishers
required by the United States Coast Guard are
the minimum necessary. Silverton recommends
exceeding the minimum requirements by placing
additional fire extinguishers where they may be
needed. Inspect all fire extinguishing equipment
frequently and review emergency plans on a
regular basis.
• Unless your yacht is well equipped with
charts, head for shore at the first sign of fog and
wait until conditions improve before continuing
your cruise. If you have charts on board, take
your present location bearings as the fog sets
in, mark your position, and continue to log your
course and speed.
• Sound your horn or fog bell at the appropriate
As a yacht owner, you should develop a Fire
Response Plan and familiarize all passengers
with this plan before departing on your cruise.
The Fire Response Plan will identify the type
of fire you may encounter and the appropriate
reaction to quickly extinguish it before it gets out
of control. Having a Fire Response Plan in place
and the assignment of certain responsibilities to
your passengers will result in faster and more
accurate decisions and reactions in the event of
a fire aboard your yacht.
intervals to warn other vessels of your presence.
Refer to the “Rules of the Road” for information
concerning the proper duration and interval of
the fog signal.
Important: All passengers on board your yacht
should know the location of your fire extinguishers and be familiar with their use.
• REDUCE YOUR SPEED.
• Be certain all persons on board are wearing
their PFD.
• Station a person forward as a lookout.
• Listen for fog signals from other vessels and
In the event a fire does start aboard your yacht,
follow these guidelines:
be aware of their presence. If possible, determine
their proximity to your yacht, but remember,
sound carries a long distance over water and
can be deceiving.
• If you detect a fire or suspect a fire aboard
your yacht, immediately turn OFF your engines
and electrical power supply. DO NOT turn OFF
power to your VHF radio.
• If there is any doubt concerning the safety of
continuing your excursion, anchor your yacht.
Listen for other fog signals while continuing
to sound your fog bell or horn. Continue your
cruise when conditions improve.
• Be certain all persons on board put on their
PFD.
• If the fire is in the engine/generator compartment, DO NOT open the hatch. The fire will flare
with the sudden introduction of fresh air.

variety of bottom surfaces.
Your 453 MotorYacht is equipped with an
Anchor Cleat and its purpose is to secure the
anchor line after the anchor is set. If your 453
MotorYacht is equipped with an optional
anchor windlass, the anchor cleat will also
eliminate unnecessary pressure on the windlass
clutch and maintain the proper “scope” (length
of released anchor rode) in the event of windlass failure. If your 453 MotorYacht is not
equipped with an optional anchor windlass, the
anchor cleat is located aft of the anchor in the
recessed walkway. If your 453 Motor Yacht is
equipped with an optional anchor windlass, the
anchor cleat is located between the anchor and
the anchor windlass in the recessed walkway
(See photograph on Page 52, which illustrates
the location of the Anchor Cleat).
Anchor Chain or Line (Rode)
The Anchor Rode on your 453 MotorYacht
may be chain, rope, or a combination of both
and, depending on the option you selected when
you purchased your yacht from your Silverton
dealer, the length is as follows:
Standard Equipment: Two hundred (200) feet of
nylon rope, 5/8 inch in diameter, and forty (40)
feet of 5/16’ chain.
Optional Windlass Equipped (Standard): Forty
(40) feet of chain coupled to Two hundred (200)
feet of nylon rope, 5/8 inch in diameter.
51
Anchor Safety Chain
Rope Locker
The Anchor Safety Chain on your 453 Motor
Yacht secures the anchor in its normal mounted
position, preventing it from falling in the event
the anchor windlass becomes disengaged, allowing the chain/rode to slip.
Your 453 Motor Yacht is equipped with a Rope
Locker, which is located on the Starboard side
of the recessed walkway immediately aft of the
anchor. The purpose of the Rope Locker is to
store the anchor rode in a convenient location removed from the deck surface. The Rope Locker
is accessed by a hatch, which covers the locker
and prevents you or your passengers from accidental falls into the storage well (See previous
photograph, which illustrates the location of the
Rope Locker).
Anchor Windlass (Optional)
Your 453 Motor Yacht may be equipped with
an optional power Anchor Windlass, which is
located in a recessed well in the forward portion of the deck immediately to the rear of the
anchor. The purpose of the Anchor Windlass is
to assist in lowering and raising the anchor with
a minimum of manual effort. The Anchor Windlass operates on DC electrical power and may
be operated from either the helm station or foot
controls, which are located on the deck adjacent
to the windlass. Be certain the Anchor Windlass
breaker switch and the battery switch are turned
to the ON position. The helm station control
consists of a manual rocker-type switch, located
on the helm switch panel (See Console Layout
on Page 162, which illustrates the location of
the anchor windlass switch). The foot controls,
located adjacent to the Anchor Windlass, consist
of two (2) foot depressed switches: the RED
switch lowers the anchor; the GRAY switch
raises the anchor (See photograph below, which
illustrates the location of the Anchor Windlass,
the foot depressed control switches, the Anchor
Cleat and the Rope Locker).
Scope
Scope is defined as the ratio of the length of
the anchor rode to the vertical distance from
the anchor chock to the bottom surface (water
depth plus the height of the anchor chock above
the water). Under favorable current, tidal and
weather conditions, a Scope ratio of 8:1 is considered satisfactory. If the rode is chain, the ratio
may decrease to 5:1 under the same favorable
conditions. It may be necessary to increase the
Scope ratio under unfavorable weather conditions, such as severe wind and tidal currents, to
hold your yacht fast to the bottom.
EXAMPLE:
Water Depth: Ten (10) feet.
Height of Anchor Chock Above Water: Seven
(7) feet (Approximate height of your 453).
Required Length of Anchor rode for 8:1 Ratio:
136 feet.
52
The procedure to properly anchor your 453 Motor Yacht is as follows:
• Secure the anchor safety chain to prevent accidental release of the anchor.
• Slowly approach your desired anchorage from
In extreme wind and current
conditions, excessive force may be applied to
the anchor windlass while retrieving the anchor
rode, which could result in damage or failure of
the unit. Avoid this excessive force by operating
your yacht slowly forward while retrieving the
anchor rode with the windlass operated from the
helm control. Be certain to maintain tension on
the anchor rode while retrieving to allow proper
operation of the windlass. Once the anchor is
free from the bottom, cease forward motion of
your yacht.
downwind and against the current, if possible.
• Stop all forward motion of your yacht and
lower the anchor after releasing the safety
chain.
• When the anchor touches the bottom, release
sufficient anchor rode to the desired scope ratio
while slowly operating your yacht in reverse.
• Affix the anchor rode to the anchor cleat and
“set” the anchor into the bottom.
• Adjust your scope ratio as needed to completely secure your yacht.
The procedure to properly release your 453 Motor Yacht from its anchorage is as follows:
•
Release the anchor rode from the anchor
cleat.
• If your 453 Motor Yacht is not equipped
with an optional anchor windlass, retrieve the
anchor rode in a hand-over-hand manner until
the anchor breaks free of the bottom.
• If your 453 Motor Yacht is equipped with an
optional anchor windlass, depress the rockertype switch marked “Windlass” to retrieve the
anchor rode and raise the anchor. If operating
the windlass from the foot-depressed switches,
depress the GRAY switch to raise the anchor.
• Continue retrieving the anchor rode until the
anchor breaks free of the bottom.
• Raise the anchor to its normal resting position
in its anchor chock.

AUTOMATIC FIRE
EXTINGUISHER
SYSTEM
The SEA-FIRE Model BB-400 automatic fire extinguishing system on your 453 Motor Yacht is
equipped with a GREEN indicator light, located
on the helm switch panel (See Console Layout
on Page 162, which illustrates the location of the
Halon System indicator light). The purpose of
this indicator light is to alert the operator of the
charge/discharge status of the Automatic Fire
Extinguishing System. The indicator light will
illuminate when the ignition switch is turned to
the ON position if the system is fully charged. If
the indicator light fails to illuminate after turning on the ignition switch, carefully examine the
exterior of the engine/generator compartment for
evidence of a fire that may have discharged the
system by looking for signs of “scorching” and
by your sense of smell.
________________
Your 453 Motor Yacht is equipped with a SEAFIRE Model BB-400 Automatic Fire Extinguisher System, which is permanently mounted
on the aft bulkhead of the engine compartment
(See Mechanical Layout on Page 161, which
illustrates the location of this fire extinguishing
system). The Automatic Fire Extinguisher
System (AFE) is designed for use in enclosed
compartments that are not normally occupied
by passengers and are not normally subject
to weather or water exposure. The SEA-FIRE
Model BB-400 automatic fire extinguisher is
designed to extinguish Class B fires (flammable
liquids) and Class C fires (electrical), which
would be the type that would normally occur
within the confined area of the engine/generator
compartment.
If the Green indicator light
does not illuminate after turning on the ignition
switch or if it turns off at any time during operation of your yacht, either at dockside or while
underway, DO NOT open the engine compartment for at least ten (10) minutes. Opening the
engine compartment immediately will allow air
to enter and may cause a fire “flashback”, possibly resulting in serious injury or death. The
sudden rush of air into the engine compartment
may also render the automatic fire extinguishing
system ineffective.
NOTE: The SEA-FIRE Model BB-400 automatic fire extinguisher system DOES NOT
replace the need for additional portable-type
fire extinguishers required by the United States
Coast Guard. Refer to the Boating Safety Section of this Owner’s Manual for the type and
quantity of portable fire extinguishers required
for your 453 Motor Yacht.
If you do not observe or smell any evidence of a
fire and you have waited the recommended ten
(10) minutes, open your engine compartment
and examine the Halon 1301 container actuator
to determine if it has been discharged. Refer
to the SEA-FIRE Manual, which illustrates the
charged and discharged position of the actuator.
If the system has been discharged or appears
charged, but the indicator light does not illuminate, see your Silverton dealer for further
inspection and repair, if necessary.
The SEA-FIRE Model BB-400 automatic fire
extinguisher is activated when the engine/generator compartment reaches 165° Fahrenheit/74°
Celsius. The system releases HALON 1301 into
the compartment, which immediately converts
to a safe, odorless, and electrically non-conductive vapor that will not harm the components in
the engine/generator compartment. In contrast
to other fire extinguishing materials, HALON
1301 leaves no residue, assisting in the eventual
cleaning of the compartment.
55
In the event of an engine/generator compartment
fire, the following steps should be taken to avoid
the likelihood of personal injury or death and to
minimize property damage:
REFER TO THE SEA-FIRE MANUAL FOR
A DETAILED DESCRIPTION OF YOUR
AUTOMATIC FIRE EXTINGUISHER
SYSTEM. BE CERTAIN TO COMPLETE
THE SEA-FIRE WARRANTY CARD AND
MAIL TO THE MANUFACTURER WITHIN
10 DAYS OF YOUR PURCHASE.
• Remain calm and avoid panic.
• Immediately turn OFF all electrical power,
including the engine ignition and the engine
compartment ventilation blowers.
NOTE: DO NOT turn OFF power to your VHF
radio.
• DO NOT open the engine/generator compartment for at least ten (10) minutes to allow the
Halon 1301 vapor to extinguish the fire.
• Remove your portable fire extinguisher from
its mounting bracket and prepare it for use, if
necessary.
• Instruct all passengers to put on their Personal
Flotation Devices (PFD’s) and move away from
the source of the fire.
• Contact the United States Coast Guard on
your VHF radio and advise of your situation and
location. Maintain radio contact until the crisis
has ended and assistance has arrived.
• If the fire is successfully extinguished, examine the engine compartment components for
damage. DO NOT restart your engines if any
damage is noted. Request towing assistance to
a safe harbor and contact your Silverton dealer
for a thorough inspection and repairs.
56
BILGE PUMP
SYSTEM
Visually inspect each bilge pump for any debris
that may have accumulated. Remove any debris
noted.
________________
Manually test each bilge pump by activating
the manual switches located on the AC/DC
Electrical Panel. Listen to each bilge pump as it
is manually activated. They should emit a quiet
“whirring” sound. If any abnormal sounds are
noted, contact your Silverton dealer for further
inspection and replacement, if necessary.
The purpose of the Bilge Pump System is to
remove any water that may accumulate within
the bilge area of your yacht (a nominal amount of
water in the bilge area is normal). The bilge area
is defined as the interior area of the hull below
the designed waterline. Your 453 Motor Yacht is
equipped with three (3) Mayfair bilge pumps that
are capable of pumping 1250 gallons of water
per hour. The bilge water is pumped overboard
through hull fittings located on the side of the
hull above the waterline (See Thru-hull Layout
on Page 157 and 158, which illustrates the location of the bilge pump discharge ports).
IMPORTANT: After testing each bilge pump
by turning ON the manual switches, be certain
they are turned OFF. The constant operation of
the bilge pumps will eventually discharge the
batteries.
Location of the bilge pumps is as follows (See
Mechanical Layout on Page 161, which illustrates the location of the bilge pumps):
• One bilge pump forward
• One bilge pump amidships
(Engine compartment area)
• One bilge pump aft
Normal operation of the bilge pumps is automatic. Each bilge pump is equipped with a float-type
switch that will automatically activate the pump
when the bilge water reaches a certain level. The
automatic switches are connected directly to
the batteries and will operate even if the battery
switch is turned OFF. Each of the bilge pumps
can also be activated manually by individual
switches located on the AC/DC Electrical Panel
(See AC/DC Electrical Panel Layout on Page
163, which illustrates the location of the manual
bilge pump switches). The bilge pump will operate continuously until the manual switch is
turned OFF. The battery switch must be turned
ON to operate the bilge pumps manually.
Periodic maintenance of the bilge pumps should
consist of the following:
57
58
BILGE VENTILATION
SYSTEM
Bilge Ventilation Vent
(Port Side)
________________
The engine and generator
compartments on your 453 Motor Yacht are
enclosed areas and are subject to the accumulation of dangerous fuel fumes. If these fumes
are not ventilated or properly exhausted from
the engine/generator compartment, they may be
ignited, resulting in fire or explosion and possible injury or death.
Your 453 Motor Yacht is equipped with two (2)
ventilation vents located on each side of the hull
directly under the salon window. These vents
lead directly into the Engine room. Ventilation
through the intake vent is natural and exhaustion
of the ventilating air through the vents is created
by the use of two (2) bilge blowers, located in
the engine room. (See Mechanical Layout on
Page 161, which illustrates the location of the
bilge blowers).
Bilge Ventilation Vent
(Starboard Side)
59
Operation of the bilge blowers is as follows:
• The battery switch must be turned to the ON
position (See photograph on Page 31, which illustrates the location of the battery switch).
• The bridge electrical breaker switch on the
bilge DC Panel, located on the forward bulkhead
of the engine room, must be turned ON .
• Depress the blower motor switch, located on
the helm switch panel (See Console Layout on
Page 162, which illustrates the location of the
blower motor switch). The small light located
on the blower switch will illuminate to indicate
the blower motors are in operation.
• Operate the blowers to dissipate heat or expel
fumes and odors, which may have accumulated
in the bilge as needed.
General maintenance of the bilge blower motors
is minimal, as they are sealed units. If they fail
to operate after being turned on, make sure all
breaker switches are turned ON. If the blower
motors still fail to operate, check the in-line fuse
located on the electrical input line adjacent to
the blower motor. If the fuses are in operable
condition and the blower motors do not operate,
contact your silverton dealer for further inspection or replacement, if necessary.

BONDING
SYSTEM
current purposes. This network of wires is then
attached to the sacrificial zinc anode located
on the transom, which allows corrosion of the
anode, but prevents corrosion of the underwater
components.
________________
The purpose of the Bonding System is to protect your yacht’s underwater components from
electrolysis and galvanic corrosion. Examples
of underwater components would be the propellers, propeller shafts, rudders, engine/generator
seawater intake valves, and any other metallic
parts that may come in contact with seawater.
General maintenance of the Bonding System
consists of yearly replacement of the sacrificial
zinc anode located on the transom and all other
zinc anodes located on the propeller shafts,
rudders, etc. and should be completed during
the spring launch procedure. The anodes may
require more frequent replacement, depending
on your docking location and the length of your
boating season. If possible, check the anodes for
excessive corrosion midway through your boating season. If excessive corrosion is noted, have
your dealer or a competent technician replace
the sacrificial zinc anodes. Periodically check
the wiring connections to make sure they are
tight and free of corrosion. Tighten and clean
connections as necessary.
Electrolysis and galvanic corrosion occurs primarily in salt water, but can occur to a lesser
degree in fresh water. Salt water allows electric
current to flow from anodic to cathodic material.
Any two metals from two components and their
relative positions in the galvanic rating table will
determine which metal loses material (anode)
and which metal remains largely undisturbed
(cathode). The distance apart on the galvanic
table of the two metals determines the rate of
wear. To help prevent corrosion, sacrificial zinc
anodes are fitted to the underwater components
of your yacht, such as the propeller shafts and
rudders. A large sacrificial zinc anode plate
is also attached to the underwater area of the
transom (See photographs on Page 19 and 20,
which illustrates the location of the zinc anodes).
The purpose of these sacrificial zinc anodes
is to attract any destructive electrical currents
away from the metallic underwater components,
thereby preventing their eventual corrosion and
allowing the corrosion of the sacrificial zinc
anodes. The sacrificial zinc anodes are considerably easier and cheaper to replace and their
deterioration will not affect the performance
of your yacht, as would the deterioration of a
propeller or rudder.
NOTE: Silverton recommends placing sacrificial zinc anodes on the following components:
• Propeller shafts
• Rudders
• Trim Tabs
IMPORTANT: DO NOT paint any of the sacrificial zinc anodes as it will retard the flow of
electric current through them and render them
ineffective.
The Bonding System is a network of wires (color
coded green) that are connected to all metallic
underwater components within the interior of the
hull, which makes them one unit for electrical

When Carbon Monoxide Gas is detected by the
CO monitor, the following visual and audible
signals will appear:
Indicator light flashes alternating RED/GREEN
accompanied by a “BEEP” sound every fifteen
(15) seconds. Depressing the “Test/Reset”
switch will not discontinue the visual and audio
signal. See your Silverton dealer for inspection
and replacement of the unit(s), if necessary.
Low CO Warning
YELLOW flashing indicator light accompanied
by a “BEEP” sound every five (5) minutes. The
YELLOW indicator light will continue to flash
until the presence of CO has lowered to an
acceptable level. If the CO level has not been
lowered to an acceptable level, an alarm will
sound in approximately fifteen (15) minutes.
Contact a qualified technician to locate and
repair the source of the Carbon Monoxide Gas
and DO NOT enter your yacht until repairs have
been made and the CO has been brought to an
acceptable level.
Maintenance of your CO monitors is as follows:
• Test each monitor after removing your yacht
from storage, prior to departing on each cruise
and on a weekly basis. Refer to the SAF-TALERT User’s Manual included with your
owner’s packet for the proper test procedure.
• Frequently observe the color of the indicator
CO Alarm
light on each CO monitor and during testing to
be certain the light is functioning properly.
RED flashing indicator light accompanied by a
pulsed alarm sound. This indicates the presence
of a dangerous level of Carbon Monoxide Gas
and IMMEDIATE ACTION IS REQUIRED.
Contact a qualified technician to locate and
repair the source of the Carbon Monoxide Gas
and DO NOT enter your yacht until repairs have
been made and the CO has been brought to an
acceptable level. After depressing the “Reset”
switch, the RED indicator light will continue
to flash and the alarm will produce a “BEEP”
sound every thirty (30) seconds until the CO is
lowered to the Low CO Warning level. If the
CO is not lowered to this level, the pulsed alarm
will re-sound in approximately six (6) minutes.
The Low CO Warning alarm will activate if
the Carbon Monoxide Gas is lowered to the low
concentration level.
• Vacuum the dust off the CO monitor cover
with the brush attachment of your vacuum
cleaner at least once a year and more frequently
if your yacht is maintained in a dusty climate.
• Frequently clean the CO monitor cover with
a damp cloth to remove all dirt and grease that
may accumulate. Dry with a soft, dry cloth.
• DO NOT spray cleaning agents or waxes
directly onto the CO monitor cover.

CARBON MONOXIDE (CO)
DETECTOR
SYSTEM
________________
Carbon Monoxide Gas (CO)
is colorless, odorless, and tasteless. It is highly
poisonous, endangering lives even at very low
levels of concentration. Mild exposure causes
headaches and fatigue, often resembling “flulike” symptoms. Medium exposure causes
severe headaches, drowsiness, nausea, and
rapid heart rate. Extreme exposure results in
unconsciousness, convulsions, cardiorespiratory failure, and death. If Carbon Monoxide
Gas (CO) is detected in your yacht, immediately
contact a qualified technician to locate and repair
the source of the poisonous gas. DO NOT enter
your yacht until repairs have been made and the
Carbon Monoxide Gas (CO) is lowered to an
acceptable level.
Your 453 Motor Yacht is equipped with three
(3) SAFE-T-ALERT Carbon Monoxide Gas (CO)
detector monitors, which are located within the
interior as follows (See proceding photographs
, which illustrate the location of the CO monitors):
• Forward V- Berth
• Starboard Guest Stateroom
• Aft Master Stateroom
• Salon
Each CO monitor is operated by DC electrical
power and they are connected directly to the batteries. It is not necessary for the battery switch
to be turned ON for them to operate.
Operation of the CO monitors requires a ten (10)
minute warm-up period, during which time, the
sensor element is cleaned and the unit is stabilized. During this ten minute warm-up period,
the GREEN indicator light will flash ON and
OFF. The GREEN indicator light will remain
ON after the completion of the warm-up period
until the presence of Carbon Monoxide Gas is
detected. If the GREEN indicator light does not
illuminate, check all wiring connections and
clean and tighten, if necessary. If the GREEN
indicator light still fails to illuminate, contact
your Silverton dealer for inspection and replacement. DO NOT attempt to make any repairs to
the unit(s) yourself.
65
NOTE: The bilge pumps, carbon monoxide detector and radio memory are NOT disconnected
from their power source when the battery switch
is turned to the OFF position. These accessories
are connected directly to the battery and do not
require a switch for operation.
ELECTRICAL
SYSTEM
________________
This section describes the various components
of the Electrical System on your 453 MY and
also includes a Trouble Shooting Guide for your
convenience.
Battery Charging System
The batteries maintain their charge from alternators, which are located on each engine. The
alternators supply charging power to the batteries only while the engines are running. Your 453
MY also has a converter, located in the Engine
Room, which converts 120 volt AC electrical
power from either the generator or shore power
into 12 volt DC electrical power.
Power Systems Operation Procedures
Batteries
The DC Electrical System obtains its source of
power from two (2) batteries, located in the engine compartment. The negative terminal of each
battery is attached to a grounding stud on each
engine. This is known as a “negative ground
system” and is the approved system for marine
DC electrical systems. The battery wiring system
has two color-coded wires. The yellow wire is
the ground (negative) wire and the red wire is the
positive (hot) wire. Both batteries are connected
to a battery switch (See photograph below, which
illustrates the location of the battery switches).
The positions on the battery switch are ON
and OFF. The switch must be turned to the ON
position to supply power to the DC electrical
system. When the battery switch is turned to the
OFF position, power is disconnected to the DC
electrical system.

FRESH WATER
SYSTEM
Fill the fresh water tank ONLY
with potable water that is safe for drinking. DO
NOT fill with water that may be of questionable
quality as serious illness or death may occur.
________________
The purpose of the Fresh Water System is to
provide a supply of pressurized potable water
to the Galley, Heads, and Transom Exterior
Shower on demand and as needed. Your 453
Motor Yacht has two (2) separate systems
that are independent of each other and they are
identified as follows:
Fresh Water Pump: the fresh water pump is
located to the rear of the water heater (See Mechanical Layout on Page 161, which illustrates
the location of the water heater and the fresh water pump). The fresh water pump operates on DC
electrical power controlled by a breaker switch
located on the AC/DC Electrical Panel (See
AC/DC Electrical Panel Layout on Page 163,
which illustrates the location of the fresh water
pump breaker switch). The fresh water pump
is equipped with an automatic pressure switch
and when it is supplied with electrical power, it
will operate until the entire fresh water system is
pressurized to a pre-set level. Once the required
pressure is obtained, the fresh water pump will
automatically shut off. The fresh water system
should maintain the pre-set level of water pressure until one of the faucet or shower valves is
opened. When the required pressure is lowered
below the pre-set level, the fresh water pump
will automatically return to operation.
• Fresh Water Pump System
• Dockside Water Supply System
Fresh Water Pump System
The Fresh Water Pump System on your 453
Motor Yacht consists of the following components:
Fresh Water Tanks (190 gallon capacity 2 x
95 gallon): The fresh water tanks are located
beneath the berth in the aft stateroom (See Mechanical Layout on Page 161, which illustrates
the location of the fresh water tanks). You can
monitor the level of the tanks by looking at the
water tank gauge (located under the sink in the
fwd. head and illustrated below). It is filled
through a fill fitting that is marked “WATER”
on the fill cap, which is located on the Starboard
side of the deck adjacent to the mid- deck “Sidewalk” (See Deck Layout on Page 159, which
illustrates the location of the fresh water tank
fill fitting).
Fresh Water Filter: The water pumped from the
fresh water tank flows through a filter located
on side of the fresh water pump. Its purpose is
to remove impurities that may be present in the
fresh water system prior to its consumption.
The filter is easily removed from the fresh water
pump and should be cleaned on a regular basis
(See photograph below, which illustrates the
location of the Fresh Water Filter).
75
Fresh Water Lines (Cold Water and Hot
Water): The fresh water lines carry the water
from the fresh water tank to the water heater
and the various faucets located in the Galley
and Head areas of your 453 Motor Yacht. They
are constructed of polybutylene plastic material
and are 1/2 inch inside diameter. The COLD
WATER lines have pale blue manufacturer’s
lettering and the HOT WATER lines have pale
red manufacturer’s lettering for identification
purposes . The fresh water lines require minimal
maintenance, but they should be visually examined on a regular basis for any leaks, chafing,
or cracking. Tighten any loose connections as
necessary. See your Silverton dealer for inspection of any suspected defective fresh water lines
and their replacement, if necessary.
Connect this system ONLY to
a potable water system that is safe for drinking.
DO NOT use water that may be of questionable
quality as serious illness or death may occur.
When you are connecting your system to a
dockside water supply, be certain to examine all
connections and water lines for any leaks. If any
leaks are noted, turn OFF the water supply immediately and make the necessary repairs before
you again turn ON the water supply. Remove any
trapped air from the water system by opening
all faucets until the air is exhausted and there is
a steady flow of water. Close the faucets after
the air is removed.
Dockside Water Supply System
Always turn OFF the dockside
water supply source when leaving your yacht
unattended. A leak in the system could result in
flooding and may cause your yacht to sink.
Your 453 Motor Yacht is equipped with a dockside water inlet located in the transom storage
compartment (See photograph below, which illustrates the location of the dockside water inlet).
This system operates independently of the Fresh
Water Pump System and simply depends on its
connection to a suitable garden-type water hose
for its supply of fresh water. When the water
supply is connected to the water inlet and turned
ON, the system is automatically pressurized
without the need for the fresh water pump. The
water entering this system will not fill the fresh
water tank; a check valve, located in the pressure
line of the fresh water pump, prevents the water
from entering the fresh water tank.
REFER TO THE WINTERIZATION AND
STORAGE SECTION OF THIS OWNER’S
MANUAL FOR THE PROPER PREPARATION AND MAINTENANCE OF YOUR
FRESH WATER SYSTEM PRIOR TO SEASONAL STORAGE OF YOUR YACHT.
76
FUEL SYSTEM
________________
Diesel fuel is extremely flammable. Failure to follow these recommendations
and the rules of good common sense could result
in fire or explosion, which could cause personal
injury or death.
Each fuel tank is equipped with a fuel level sending unit, which provides an electrical signal to
the fuel gauge to indicate the fuel level. You can
toggle between the two tanks by using the Fuel
Gauge Selector Switch. (See Console Layout
on Page 162, which illustrates the location of
the Fuel Gauge Selector Switch). Toggle up
on the switch for the port tank and down for the
starboard tank.
The purpose of the Fuel System is to maintain
the necessary supply of fuel to the engines and
generator (if so equipped) upon demand and as
needed. The fuel system on your 453 Motor
Yacht is comprised of the following components, which will be described separately:
•
•
•
•
•
•
•
•
Fuel Tanks
Fuel Tank Fills and Vents
Fuel Tank Grounding System
Fuel Distribution Hoses
Fuel Supply Valves
Fuel Filtration
Generator Fuel Selector Valve
Fuel Gauge and Selector Switch
The fuel tanks should be inspected for signs of
leaks, corrosion and/or pitting at least once each
year. Corrosion normally appears as a white
chalky or flaky appearance on the surface of
the tank. Sometimes it also appears as pitting
or small pockets of missing aluminum. Another indication of corrosion could be bubbles
on the paint that coats the fuel tank. If any of
these conditions are present, have an authorized
Silverton Service Technician inspect the tank(s)
immediately. If a leak is found, turn OFF battery switches, disconnect the shore power (See
Shore Power - Connecting and Disconnecting
on Page 67, which explains the proper and safe
method for disconnecting your shore power) and
disable any possible source of ignition. Contact
your Silverton dealer or Silverton Customer
Service immediately.
Fuel Tanks
Your 453 Motor Yacht is equipped with two
(2) fuel tanks, each having a capacity of 250
gallons, for a total fuel capacity of 500 gallons.
Both fuel tanks are located within the engine
compartment; one tank is located on the Port
side and one tank is located on the Starboard side
(See Mechanical Layout on Page 161, which
illustrates the location of the fuel tanks). The
Port fuel tank supplies fuel to the Port engine
and the Starboard fuel tank supplies fuel to the
Starboard engine. Either tank can supply the
generator, if so equipped (See adjacent photograph , which illustrates the Generator Fuel
Selector Valve).
Leaking fuel is a fire and explosion hazard; personal injury or death could
occur.
77
Fuel Tank Fills and Vents
the proper and safe method for disconnecting
your shore power) and disable any possible
source of ignition. Contact your Silverton dealer
or Silverton Customer Service immediately.
Each fuel tank is filled through its respective fuel
fill fitting (shown below). The cap is marked
Diesel.
Leaking fuel is a fire and explosion hazard; personal injury or death could
occur.
If any fuel hoses are in need of replacement,
be certain that ONLY USCG TYPE A1 or A2
are used.
Be sure to use Diesel fuel only,
as incorrect fuel will result in severe damage to
the engines.
The use of any hose other than
USCG TYPE A1 or A2 could result in fuel leakage. Leaking fuel is a fire and explosion hazard;
personal injury or death could occur.
The Port fuel tank fill fitting is located on the
Port side of the transom and the Starboard fuel
tank fill fitting is located on the Starboard side
of the transom (See Deck Layout on Page 159,
which illustrates the location of the fuel tank fill
fittings). The fuel fill fittings are connected to the
fuel tanks with the fuel fill hoses.
Fuel Tank Grounding System
The fuel tanks and fuel fills on your 453 Motor
Yacht are electrically grounded (or bonded) to
the ground buss of the bonding system. This
grounding system is designed to prevent the
discharge of static electricity, which could cause
a spark, especially when fueling your yacht. An
authorized Silverton Service Technician should
inspect this system at least once each year.
Each fuel tank has a hull vent fitting. These
fittings are located on the Port and Starboard
sides of the hull (See Thru-hull Layout-Port
and Starboard on Page 157 and 158, which
illustrates the location of the fuel tank vents).
The vent fittings are connected to the fuel tanks
with the fuel vent hoses. These vents allow air
to pass through them when fueling and when the
engines are drawing fuel from the tanks.
While fueling, a spark caused
by static electricity could result in fire or explosion, which could cause personal injury or
death.
The fuel fill and fuel vent hoses, fittings and
connections should be inspected for leaks and
signs of dry rot or swelling at least once a year.
If any of these conditions are present, have an
authorized Silverton Service Technician inspect
the entire fuel system immediately. If a leak is
found, turn OFF the battery switches, disconnect
shore power (See Shore Power - Connecting
and Disconnecting on Page 67, which explains
Fuel Distribution Hoses
Each engine has a fuel supply hose that runs
from the pick-up tube in the fuel tank to the
78
engine. Also, each engine has a fuel return hose
that runs from the engine to the fuel tank. The
generator has a fuel supply hose that runs to the
fuel selector valve. Then, from the valve, there
are two (2) supply hoses; one to each tank. The
fuel selector valve has dual ports, one set of ports
for supply and one for returns. The fuel return
hoses are routed similar to the supply hoses
(See photograph on Page 77, which illustrates
the Generator Fuel Selector Valve). All fuel
supply and return hoses are USCG TYPE A1
and are pre-manufactured with swedged flare
fittings on each end (See Mechanical Layout
on Page 161, which illustrates the location of
the fuel hoses).
The use of any hose other than
USCG TYPE A1 for diesel fuel supply could
result in fuel leakage. Leaking fuel is a fire and
explosion hazard; personal injury or death could
occur.
Fuel Supply Valves
Your 453 Motor Yacht is powered by Diesel
engines and is equipped with a shut off valve,
located at each fuel supply hose at its connection to its respective fuel tank pick-up tube. The
purpose of the shut off valve is to be able to stop
the flow of fuel from the fuel tank in the event
of a break in the fuel supply hose.
The fuel supply and return hoses, fittings, and
connections should be inspected for leaks and
signs of dry rot or swelling at least once each
year. A good way to examine the fuel hoses is to
run your hand along the length of the hose, including the fittings. Small leaks will be revealed
as wet spots on your hand. If any evidence of
hose deterioration is present, have an authorized
Silverton Service Technician replace all of the
hoses with USCG TYPE A1 hoses immediately.
If a leak is found, turn OFF battery switches,
disconnect shore power (See Shore Power
- Connecting and Disconnecting on Page 67,
which explains the proper and safe method for
disconnecting your shore power) and disable
any possible source of ignition. Contact your
Silverton dealer or Silverton Customer Service
immediately.
Fuel Filtration
The fuel that is supplied to the engines and
generator may contain impurities found in the
fuel tanks or contained in the fuel from your
supplier. If these impurities are not removed
prior to entering the engines/generator, performance may be seriously affected. Removal of
the fuel impurities is accomplished by external
fuel filters, which are located within the fuel
supply line.
Your 453 Motor Yacht is equipped with diesel
engines, each engine has a primary fuel filter
(See photograph on the adjacent page, which
illustrates the location of the fuel filters.)
Leaking fuel is a fire and explosion hazard; personal injury or death could
occur.
If any fuel hoses are in need of replacement, be
certain that ONLY USCG TYPE A1 is used.
79
photograph, which illustrates the location of the
Generator Fuel Selector Valve.
The generator uses a remote fuel filter. It is
located in the main generator fuel supply line,
separate from the engine fuel supply lines (See
photograph below, which illustrates the location
of the generator fuel filter. The adjacent photograph illustrates the fuel selector valve).
The Generator Fuel Selector Valve also determines the tank to which the unused fuel is returned. This fuel is always returned to the same
tank that is supplying the generator.
The fuel tank that is selected to supply the generator will display a lower fuel level than the
other fuel tank when the generator is operated
for an extended period of time. The Generator
Fuel Selector Valve can be set so that this is
reversed and fuel can be drawn from the opposite tank (See Generator Fuel Selector Valve
Diagram below, which illustrates the positions
of the valve).
An authorized Silverton Service Technician
should replace all fuel filters annually prior to
spring launch. They may need more frequent
replacement if you notice poor engine/generator
performance due to contaminated fuel.
Generator Fuel Selector Valve
The generator fuel tank selector valve, located
underneath the cabinet under the TV in the Master Stateroom, determines the tank from which
it will draw its supply of fuel (See adjacent
80
Fuel Gauge and Selector Switch
for signs of weakening, swelling or corrosion.
See your Silverton dealer for replacement of any
leaking or defective fuel system components
before starting your engines.
The purpose of the Fuel Gauge is to allow you
to constantly monitor the fuel level in the fuel
tanks. The fuel gauge on your 453 Motor Yacht
is located at the helm station on the port side of
the helm gauge panel (See Console Layout on
Page 162, which illustrates the location of the
Fuel Gauge). A manual rocker-type Fuel Gauge
Selector Switch determines which fuel tank
level (Port or Starboard). It is displayed on the
fuel gauge (See Console Layout on Page162,
which illustrates the location of the Fuel Gauge
Selector Switch). Depress the top of the switch
to read the Port fuel tank and the bottom of the
switch to read the Starboard fuel tank level.
If possible, fuel your yacht only during
the hours of daylight. Fuel spills are easier to
detect when visibility is good.
To reduce condensation and the accumulation of moisture in the fuel system, keep your
fuel tanks as full as possible, especially during
overnight docking or mooring.
When fueling your yacht in warm
weather, allow for expansion of the fuel and
DO NOT “top off” the fuel tanks. The fuel tanks
may overflow when the fuel expands after being
pumped from cool, underground tanks or when
the air temperature is cool, such as early morning
or evening.
Fueling Your 453 Motor Yacht
Fuel Quality
Never hurry through the fueling procedure. In your haste, you may overlook an
important step, resulting in improper fueling.
Refer to your Engine Manual, included with
your owner’s packet, for specific fuel requirements for your engine, i.e., recommended octane
level.
Be certain you use the correct fuel type
for your specific engine that is recommended by
the engine manufacturer; gasoline or diesel.
Fuel Additives
Refer to your Engine Manual for recommendations concerning fuel additives.
Using the wrong type of fuel
will result in severe damage to the engines.
Refer to the Winterization and Storage Section
of this Owner’s Manual concerning the use of
fuel stabilizers. Always follow the manufacturer’s recommendation when using fuel additives
or stabilizers.
Fueling Procedure
Safely and securely moor your yacht to
the fuel dock.
General Guidelines For Fueling Your Yacht
Turn the engines, generator and battery
switches OFF to prevent the possibility of electrical spark.
Leaking fuel is a fire and explosion hazard; personal injury or death could
occur.
Disconnect shore power (See Shore
Power - Connecting and Disconnecting on
Before fueling, check the fuel system
for leaks. Check the fuel system components
81
Page 67, which explains the proper and safe
method for disconnecting your shore power).
After pumping several gallons of fuel,
STOP and inspect the engine compartment for
any signs of fuel leakage. DO NOT continue
the fueling process if leaks are noted. Have an
authorized Silverton Service Technician inspect
and repair the leak before proceeding.
Extinguish all smoking materials and any
other items that may produce a spark or flame.
A spark or open flame can ignite
fuel or fuel vapor, which could cause personal
injury or death.
Leaking fuel is a fire and explosion hazard; personal injury or death could
occur.
Completely close all ports, hatches,
windows, doors and compartments. Silverton
recommends that all guests depart your yacht
during the fueling process.
If no leaks are noted, continue filling
the fuel tanks and be certain to allow for fuel
expansion in warm weather. As the fuel tanks
fill near the top, slow the fuel entry to avoid
overflow through the fuel tank vent (See Thruhull Layout-Port and Starboard on Page 157
and 158, which illustrates the location of the fuel
tank vents).
Fuel evaporates at a very low
temperature. Vapors can collect in areas inside
your yacht and create an explosion hazard. An
explosion will cause serious personal injury or
death. Close all ports, windows, hatches, doors
and compartments before fueling.
After the fuel tank is filled, remove the
fuel nozzle and replace the fuel fill cap, securing tightly. If any fuel was spilled, clean it up
immediately.
Touch the nozzle of the fueling hose to
the fill cap to discharge any existing static electricity.
After the fueling process is complete,
open all hatches, doors, and compartments. Visually examine all fuel system components for any
sign of leakage and if noted, have an authorized
Silverton Service Technician inspect and repair
the leak.
Remove the fuel fill cap and insert the
fuel hose nozzle into the fill pipe.
Always maintain contact between the
fuel hose nozzle and the fuel fill pipe to avoid the
possibility of static electricity build-up. If static
electricity forms during the fueling process, it
may generate a spark, resulting in igniting the
fuel.
Turn battery switch ON and operate the
bilge blower motors for at least five (5) minutes
to ventilate the engine compartment. Refer to the
Before Starting The Engines Section below.
Start the engines and return your yacht to normal
operating condition. DO NOT smoke until you
are a safe distance away from the fuel dock.
While fueling, a spark caused
by static electricity could result in fire or explosion, which could cause personal injury or
death.
82
Before Starting The Engines
Before starting the engines or generator
(if so equipped), ALWAYS inspect the engine
and generator compartments for fuel leakage.
Sniff to detect any odor of fuel. If leakage or
fuel odor are present, open all doors and windows for ventilation and evacuate your yacht
immediately.
Notify the dockmaster and have an authorized Silverton Service Technician inspect
the entire fuel system and repair the leak before
proceeding.
Leaking fuel is a fire and explosion hazard; personal injury or death could
occur.
If you do not detect any fuel odors and
there are no fuel leaks, open the doors and windows to ventilate your yacht.
Refer to the Operating Your Yacht Section of this Owner’s Manual for engine starting
instructions.
83
84
FUEL SAFETY CHECKLIST FOR BOARDING
This fuel safety checklist is designed to be used as a quick reference to minimize the risks associated
with fuel hazards. You should refer to this checklist every time you board your yacht. Read your owner’s
manual so that you have a full understanding of the fuel system on your yacht.
Diesel fuel is extremely flammable. Failure to follow these recommendations
and the rules of good common sense could result in fire or explosion; which could cause personal
injury or death.
Before approaching your yacht extinguish all smoking materials and make certain there are no other sources of possible ignition near your yacht.
Approach your yacht alone to make the initial inspection. Have your guests and
crew standby a safe distance away.
From the dock visually inspect your yacht for any fuel leaks from the deck fills
or hull vents and take notice if there is any odor of fuel.
Once onboard, open cabin door and sniff at doorway then inside cabin for fuel
odor.
Open the engine compartment hatch and sniff for fuel odor.
Inspect the engine compartment and all bilge compartments for fuel leaks and
sniff for fuel odor.
If there are any signs of fuel leakage, either visually or by odor, open doors,
hatches, and windows. Evacuate the boat and inform the Dock Master. Have an
authorized Service Technician inspect your yacht.
If no signs of fuel are present, board your guests and crew.
Run exhaust blowers for five minutes before starting the engines or generator.
Always be aware of the hazards associated with fuel and practice good common
sense.

GENERATOR
SYSTEM
Operation of the Generator System is as follows:
________________
Turn ON the Generator System battery
switch, located on the forward bulkhead of the
engine room.
Your 453 Motor Yacht, has a Generator System, manufactured by Kohler Company and
factory installed at the Silverton plant. It has
13.5 kilowatt rating and operates on diesel fuel.
As discussed in the Fuel System Section of this
Owner’s manual, fuel is supplied to the generator from either fuel tank, depending on your
selection at the Generator Fuel Selector Valve
(Refer to the Fuel System Section on Page 77
for information concerning the Generator Fuel
Selector Valve). The Generator’s Electric power
is controlled by a breaker switch, located on the
AC/DC Electrical Panel (See AC/DC Electrical Panel on Page 163, which illustrates the
location of the breaker switch that controls the
Generator System). The system START and
STOP switch is also located on the AC/DC
Electrical Panel as is a slide bar switch that
permits you to change from generator electrical
power to shore electrical power as desired. The
Generator System is located in the generator
compartment, which is accessed through the
engine room door, and the Aft cabin steps.(See
photograph below, which illustrates the location
of the Generator System ).
Check sea strainer for debris, and remove, if noted.
Be certain the seawater intake valve that
services the generator is in the OPEN position.
The valve is open when the handle is parallel to
the valve body (See photograph below, which
illustrates the location of the generator seawater
intake valve and its OPEN and CLOSED positions).
Turn ON the breaker for the generator.
Move slide bar switch to generator power
mode.
Operate generator compartment blower
motor to dissipate heat or expel fumes as needed.
Check for presence of Diesel Fuel odor
in the bilge.
87
REFER TO THE KOHLER COMPANY
GENERATOR MANUAL INCLUDED
WITH YOUR OWNER’S PACKET FOR
ADDITIONAL TECHNICAL INFORMATION CONCERNING THE OPERATION
AND MAINTENANCE OF YOUR GENERATOR SYSTEM.
Diesel fuel vapors in the bilge
can cause explosion and fire aboard your
yacht.
Start the generator (Refer to “Starting
Instructions” section in the Generator Manual
included with your Owner’s Packet.
Depress START switch on AC/DC Electrical Panel until generator starts.
DO NOT depress START switch
for more than thirty (30) seconds as damage to
the generator starter motor may result. If the generator does not start within 30 seconds, release
the START switch and allow the starter motor to
cool for at least sixty (60) seconds before again
attempting to start the generator.
To cease operation of the Generator system, depress the STOP switch on the AC/DC Electrical
Panel. After the generator stops running, release
the STOP switch. Continue to operate the blower
motor for several minutes to be certain the generator compartment is completely evacuated of
any fuel fumes. Return the slide bar switch to
the shore power mode and turn OFF the breaker
switch. Turn OFF the Generator System battery
switch.
Refer to “Generator” in the Electrical System
section of this manual on page 68 for using the
generator output to power the boat.

HOT WATER
SYSTEM
which is located on the AC/DC electrical panel
(See AC/DC Electrical Panel Layout on Page
163, which illustrates the location of the water
heater breaker switch).
________________
Your 453 MotorYacht is equipped with a 20
gallon water heater, which is operated by the
A/C electrical system. Cold water is supplied
to the water heater from the fresh water pump,
which is then heated for distribution when desired. Similar to the water heater in your home,
there is always a continuous supply of water to
maintain a full tank at all times. The water heater
in your 453 Motor Yacht is a “high recovery”
model, meaning the cold water entering the tank
is heated very quickly to replace the hot water
as it is used. The water heater is located in the
ceiling above the forward head.
The access panel is shown below.
NOTE: The water heater will operate on AC
electrical current only. You must either plug in
your shore power cord or operate your generator
for the water heater to function.
Allow sufficient time for the water heater
to heat its contained water before using (approximately 1/2 hour).
General maintenance of the Hot Water System
is as follows:
Inspect all water lines and their connections at regular intervals. Tighten connections as
needed. If the water lines appear worn or are not
flexible, see your Silverton dealer for replacement.
Manually operate the pressure relief
valve on the water heater at least once a year
(See photograph below, which illustrates the
location of the valve).
Operation of the water heater is as follows:
Be certain the water heater is full of water. You can easily check this by turning ON a
hot water faucet. If water flows from the faucet,
the water heater is full.
If the water heater is not full
of water, damage to the heating elements may
result when electrical power is turned ON to
the unit.
DO NOT operate the pressure
relief valve while the water heater contains hot
water. Serious burns or injury could result.
Turn ON the water heater breaker switch,
89
Flush out the water heater tank at least
once a year, if not used regularly.
Refer to the Winterization and Storage Section of this Owner’s Manual on proper
preparation for seasonal storage of the water
heater.

HYDRAULIC STEERING
SYSTEM
The Hydraulic Steering System in your 453
Motor Yacht utilizes an adjustable tilt-type
steering head, which allows you to adjust the
steering wheel angle for maximum personal
comfort. The steering head contains a vented
fill cap on single station models and on the
upper helm station ONLY on lower station
models. The vented cap is located on the top of
the steering head and forward of the steering
wheel. The lower station steering head fill cap
is NOT vented. The hydraulic fluid level should
be checked on the upper helm station ONLY. If
needed, hydraulic fluid is added at this location
to fill the reservoir to the proper level.
________________
The steering system in your 453 Motor Yacht
is manufactured by Sea Star, a subsidiary of
Teleflex (Canada, Ltd.), and is hydraulically assisted. Hydraulic assisted steering is similar to
the power steering system in your automobile
and greatly reduces the manual effort necessary
to steer your yacht and maintain the desired
course. The Hydraulic Steering System in your
453 Motor Yacht differs from your automobile,
as a separate pump is not used to circulate the
hydraulic fluid contained in the system; the
system is completely filled with hydraulic fluid
and is free of air. As you turn your steering
wheel, the hydraulic fluid is pumped by the
steering head into the appropriate fluid line, Port
or Starboard, resulting in moving the steering
cylinder in the respective direction. The steering
cylinder is connected to the rudders and they
are subsequently turned, which enables your
yacht to turn in the desired direction; to Port or
Starboard. Access to the steering cylinder can
be obtained by removing the mattress of the bed
in the Aft Master Stateroom. (See photograph
below which illustrates the steering cylinder and
its connection to the rudders).
Maintenance of the Hydraulic Steering System
should only be performed by your Silverton
dealer or a qualified technician, who is experienced in marine hydraulic systems. Periodically
examine all connections and hydraulic lines for
any signs of leakage. If any leaks are noted, contact your Silverton dealer for further inspection
and repair, if necessary.

MARINE SANITATION
SYSTEM
Each system is described as follows:
SeaLand Vacuflush Toilet
________________
This system is operated by vacuum, combined
with a small quantity of water supplied by the
pressurized fresh water system (approximately
one (1) pint per flush) and is controlled by DC
electrical power. Each toilet is equipped with
an integral vacuum breaker that prevents a
backflow of contaminated water into the potable
water supply. Vacuum energy, supplied by the
Vacuum Pump, is stored in a Vacuum Tank and
is monitored to maintain a certain level. The
Vacuum Pump is controlled by an electrical
breaker switch, located on the AC/DC Electrical
Panel (See AC/DC Electrical Panel Layout
on Page 163, which illustrates the location of
the breaker switches). As the toilet is flushed,
vacuum energy is depleted and the Vacuum
Pump will automatically activate to restore the
required level. The Vacuum Pump will operate
for approximately 30 to 90 seconds until the
system reaches the required operating vacuum
level. Toilet waste, both liquid and solid, is removed by the vacuum energy and water combination to a Waste Tank having a capacity of sixty
(60) gallons (See Mechanical Layout on Page
161, which illustrates the location of the Waste
Tank). This waste is stored in the Waste Tank
until pumped out at a proper facility. The Waste
Tank is equipped with an electronic Waste Level
Gauge, which monitors the volume of waste in
the tank for your convenience in determining
when pump-out is required (See photograph on
Page 100, which illustrates the location of the
Waste Level Gauge).
All vessels with fixed toilets that are operated on
the waterways of the United States and some foreign countries are required to be equipped with
an operable Marine Sanitation Device (MSD).
The Marine Sanitation System in your 453
Motor Yacht is a Waste Tank system, defined
by the United States Coast Guard as a Type III
System. Type III Systems permit operation of the
toilet without the direct discharge of untreated
waste after every flush. Type III Systems can be
discharged at marina dockside pump-out stations
or, if in coastal waters, at least three (3) miles
offshore.
NOTE: Overboard discharge capability must
remain inoperative while within the 3 mile limit.
This is accomplished by closing the macerator
discharge thru-hull valve (See Mechanical Layout on Page 161, which illustrates the location
of the macerator discharge thru-hull valve).
Your 453 Motor Yacht is equipped with one
of the following Marine Sanitation Systems,
depending on the option you chose from your
Silverton dealer at the time of purchase:
• SeaLand Vacuflush Toilet
• Jabsco Quiet-Flush Electric Toilet
(Fresh Water)
• Jabsco Quiet-Flush Electric Toilet
(Raw Water)
99
activates both the rinse water supply and the
macerator discharge pump simultaneously. In
addition to the push button switch, a separate
rocker-type switch may be used to control the
rinse water supply, independent of the macerator.
This feature allows conservation of your fresh
water supply as well as the ability to raise the
water level, if needed, for proper evacuation of
the toilet bowl under all conditions. To prevent
contamination of the fresh water supply, this
system is equipped with an anti-siphon breaker
contained in the water control solenoid valve.
The water control solenoid valve of each toilet
is controlled by an electrical breaker switch,
located on the AC/DC Electrical Panel (See
AC/DC Electrical Panel Layout on Page 163,
which illustrates the location of the breaker
switches). Toilet waste, both liquid and solid,
is flushed from the toilet by the macerator to
a Waste Tank having a capacity of sixty (60)
gallons (See Mechanical Layout on Page
161, which illustrates the location of the Waste
Tank). This waste is stored in the Waste Tank
until pumped out at a proper facility. The Waste
Tank is equipped with an electronic Waste Level
Gauge, which monitors the volume of waste in
the tank for your convenience in determining
when pump-out is required (See photograph on
this page, which illustrates the location of the
Waste Level Gauge).
Maintenance of your Sea Land Vacuflush Sanitation System consists of periodic cleaning of the
toilet bowl with a mild non-abrasive cleaner.
The Waste Tank should be thoroughly rinsed
after each pump-out and a sanitation system
deodorizer should be added to the Waste Tank
by flushing through the toilet.
DO NOT use chlorine-based
or caustic cleaning agents or chemicals, such as
drain opening products, in your SeaLand Vacuflush Sanitation System. Use of these products
may cause serious damage to the system’s seals
and hoses.

Jabsco Quiet-Flush Electric Toilet
(Raw Water)
This system is identical to the fresh water system in its operation, but uses raw water pumped
from the sea as its rinse water source instead of
fresh water supplied by the pressurized fresh
water system. This system is not equipped with
a separate rocker-type switch to control the
rinse water level and the volume is consistent
(approximately 1 - 2 quarts per flush). As with
the fresh water system, to prevent contamination
of the raw water supply, this system is equipped
with an anti-siphon breaker contained in the
Jabsco Quiet-Flush Electric Toilet
(Fresh Water)
This system is operated by water supplied by the
pressurized fresh water system (approximately
1 - 2 quarts per flush) and is controlled by DC

PORTABLE FIRE
EXTINGUISHER
SYSTEM
fires of the Class “B” and Class “C” type. The
Class B/C portable fire extinguisher contains
pressurized dry powder, which when released,
will leave a powder residue that smothers the
fire and removes its source of oxygen. Once the
source of oxygen is removed, the fire cannot
continue to burn and it will be extinguished.
________________
The fire extinguishers shipped with your 453
Motor Yacht should be mounted in a readily
accessible location away from the engine compartment, but in a relative position to potential
fire hazards, such as the Galley. The fire extinguishers should be mounted within plain view
and all passengers on board should be familiar
with their location and operation before departing your dock.
As a yacht owner or operator, you have the responsibility of having the required quantity of
United States Coast Guard approved portable
fire extinguishers aboard at all times, except during storage. The portable fire extinguishers must
be operational and of the proper classification.
The classification of portable fire extinguishers
and their appropriate use is as follows:
Maintenance of your portable fire extinguishers
should consist of periodic cleaning of the canisters and making certain they are easily seen
and readily accessible. Periodically examine the
gauge on each fire extinguisher to be sure they
are fully charged. If the gauge indicates the fire
extinguisher is not fully charged, contact your
Silverton dealer for replacement. DO NOT test
the charge of your portable fire extinguishers
by operation of them; it will discharge them
unnecessarily.
CLASS “A”
“Fires in ordinary combustible materials, such
as wood, paper, and cloth, where the quenching-cooling effect of quantities of water or high
water content solution cools the burning material
below the ignition temperature.”
CLASS “B”
REFER TO THE OPERATING INSTRUCTIONS DISPLAYED ON THE FIRE EXTINGUISHER CANISTERS FOR A DETAILED
DESCRIPTION OF THEIR OPERATION AND
USE.
“Fires in flammable petroleum products or other
flammable liquids, greases, etc., where the blanketing-smothering effect of oxygen-excluding
media is most effective.”
CLASS “C”
“Fires involving electrical equipment where
the electrical conductivity of the extinguishing
media is the first consideration.”
Your 453 Motor Yacht is equipped with two (2)
Class B/C portable, hand held fire extinguishers.
Class B/C fire extinguishers will effectively fight

108
PROPULSION
SYSTEM
The engine starting procedure is as follows:
Open and inspect the engine compartment. Use your sense of smell to detect the
presense of fuel fumes.
________________
Propulsion of your 453 Motor Yacht is accomplished by two inboard engines, located within
the engine compartment. The engines are fueled by diesel fuel. Each engine transmits its
power to a separate transmission, which rotates
the attached propeller shaft and the propeller,
providing forward or reverse movement of your
yacht as selected from the Morse Control unit
located on the Starboard side of the helm (See
photograph below, which illustrates the location
of the Morse Control Unit ). The transmissions
are counter-rotating. This is defined as when in
the forward shift mode and viewing forward
from aft, the Port transmission rotates the Port
propeller counterclockwise and the Starboard
transmission rotates the Starboard propeller
clockwise.
Check the bilge water level. If it appears
above normal, turn ON the bilge pump(s) and
remove the water. Determine the source of the
excess water and repair, if necessary, before
starting the engines.
Check the bilge for the presence of any
oil. Repair, if necessary.
Visually examine both seawater strainers
to ensure they are free of debris. Clean if debris
is noted.
Open both engine seawater intake valves
(See Mechanical Layout on Page 161, which
illustrates the location of the engine seawater
intake valves). The valves are open when the
handles are parallel to the valve body and intake
hose (See photograph below, which illustrates
the open and closed positions of the engine
seawater intake valves).
Access to the engine room can be gained through
the starboard guest stateroom.
109
Check all cooling and lubricating fluids (See photograph below, which illustrates
the location of the engine and transmission oil
“dipsticks”). Add engine oil or transmission oil,
if needed, but DO NOT overfill.
Do not continue to depress the
“Parrallel Start Switch” after the engine has started. Damage to the alternator(s) may result.
Turn the ignition key to START and
hold in this position until the engine starts. If
the engine starter motor does not operate, the
neutral safety switch may be out of adjustment.
Slowly and carefully move the transmission shift
control lever up and down until the starter motor
operates. See your Silverton dealer or a competent technician as soon as possible to obtain the
proper adjustment for the neutral safety switch.
Release the ignition switch as soon as the engine
starts. The engine alarm buzzer should turn OFF
when the engine oil pressure reaches normal
operating range. The automatic fire extinguisher
indicator light should remain illuminated.
DO NOT remove the cooling
system filler cap when the engine is hot. Allow
the engine to cool and then remove the presslowly, allowing the pressure to vent. Hot coolant, under pressure, may discharge violently and
result in serious personal injury and burns.
If the engine fails to start within
thirty (30) seconds, release the ignition switch.
Allow the starter motor to cool for at least sixty
(60) seconds and then try again to start the engine. Prolonged starting attempts may result in
starter motor overheating and damage.
Place the transmission shift controls at
the helm station in the neutral position. The feel
of a “detent” midway between the forward and
reverse positions indicates the neutral position.
Place the throttle controls in the idle or
“down” position.
Failure to release the ignition
switch from the START position after the engine
starts may result in serious damage to the starter
motor and/or engine flywheel.
Turn the ignition key to ON, but not to
START. The engine alarm buzzer should sound
and the automatic fire extinguisher system indicator light should illuminate.
If the engine alarm buzzer
DOES NOT turn OFF, turn OFF the engine immediately if the oil pressure gauge displays no, or
very low, oil pressure. See your Silverton dealer
for inspection and repair, if necessary. No, or
very low, oil pressure may cause serious damage
to the internal mechanism of your engine(s).
If one of the batteries is “dead” or not
sufficiently charged to start your engine, depress
the “Parallel Start Switch” simultaneously while
turning the ignition switch to START. The parallel start switch draws power from both batteries
during the starting procedure and it is located
on the helm switch panel (See Console Layout
on Page 162, which illustrates the location of
the parallel start switch). Release both switches
immediately after the engine starts.
110
Turn battery switch ON.
If the automatic fire extinguisher
indicator light DOES NOT remain illuminated,
turn OFF the engine(s) immediately and follow
the proper procedure to check for fire aboard
your yacht as detailed in the Automatic Fire
Extinguisher System Section of this Owner’s
Manual. A fire aboard your yacht may result in
serious personal injury or death.
After both engines have reached their
normal operating temperature, increase the
RPM’s to 2000 and check both voltmeters to
be certain they read between 13 and 14.5 volts.
The engine voltmeters are located on the Helm
Gauge Panel (See Console Layout on Page
162, which illustrates the location of the voltmeters).
After you have started both engines and determined they are running properly, the “warm-up”
procedure should be followed before departing
the dock/mooring. The proper “warm-up” procedure is as follows:
If the voltmeter(s) read above
15 volts, turn OFF the respective engine(s) as
damage to the alternator(s) may result.
Check the oil pressure gauges to be
certain each engine has sufficient oil pressure.
Diesel engines should have between 35 and 70
psi. If the oil pressure is lower than the normal
operating range, turn OFF the respective engine
and contact your Silverton dealer for further
inspection and repair, if necessary.
Allow the engines to run at the RPM’s
specified in the Engine Manual until they reach
the proper operating temperature. The normal
operating temperature for diesel engines is
between 170° F and 190° F. If the engine temperature rises significantly above the normal
operating range (10° F), turn OFF the respective
engine and contact your Silverton dealer for
inspection and repair, if necessary.
Visually inspect the engine compartment
for fuel, oil, and water leaks. If leaks are observed, attempt to locate the source and contact
your Silverton dealer for inspection and repair,
if necessary.
Visually inspect the exhaust system for
leaks. If any leak is observed, immediately turn
OFF the engines and contact your Silverton
dealer for inspection and repair, if necessary.
Check the transmission fluid level. The
engines should be running at idle speed and at
normal operating temperature. The transmission
fluid should read FULL on the “dipstick”. If
the fluid level is low, add sufficient transmission fluid to raise the level to the FULL mark
or slightly lower. DO NOT overfill. If the fluid
level is low, check the transmission(s) for leaks
Check the exhaust outlets for the presence of water. Water coming from the exhaust
outlets indicates proper Water should start coming out of the exhaust outlet shortly after the
engine is started. If you do not observe any water
coming from the exhaust outlet(s), turn OFF
the respective engine and contact you Silverton
dealer for inspection and repair if necessary.
REFER TO THE ENGINE MANUAL INCLUDED WITH YOUR OWNER’S PACKET
FOR ADDITIONAL INFORMATION CONCERNING MAINTENANCE REQUIREMENTS FOR THESE SPECIFIC WITH
WHICH YOUR 453 MOTOR YACHT IS
EQUIPPED.
The exhaust system is raw water
cooled. If there is no presence of water in the
exhaust outlet(s), the exhaust system may overheat, resulting in serious damage to the engine(s)
and the exhaust system components.

116
SHOWER SUMP PUMP
SYSTEM
NOTE: When operating the aft air conditioner
on your 453 Motor Yacht , the aft sump pump
breaker switch must be turned ON. Condensation from the air conditioner drains into the
Shower Sump Pump System and this water is
pumped overboard by the sump pumps.
________________
Your 453 Motor Yacht is equipped with two
(2) showers; one is located in the forward head
and the other shower is located in the aft stateroom head (See Interior Layout on Page 160,
which illustrates the location of both showers).
Each shower is equipped with a separate automatic sump pump (See Mechanical Layout on
Page 161, which illustrates the location of both
shower sump pumps). As the water drains from
the shower into the sump pump to a certain
level, it raises an automatic switch lever, which
activates the shower sump pump and the water
is pumped overboard.
REFER TO THE WINTERIZATION AND
STORAGE SECTION OF THIS OWNER’S
MANUAL FOR THE PROPER PREPARATION
AND MAINTENANCE OF THE SHOWER
SUMP PUMP SYSTEM PRIOR TO SEASONAL STORAGE OF YOUR YACHT.
The Shower Sump Pump System operates on
DC electrical power, controlled by individual
breaker switches located on the AC/DC electrical Panel (See AC/DC Electrical Panel Layout
on Page 163, which illustrates the location of
the sump pump breaker switches). A separate
breaker switch controls each shower sump pump
and they operate independent of each other.
General maintenance of the Shower Sump
Pump System involves periodic cleaning to
remove any accumulated debris. Remove the
six (6) screws securing the top cover for access
to the debris basket and automatic float switch.
If you notice that either shower does not drain
properly, check the respective sump pump basket
for debris and clean, if necessary. If the shower
still does not drain properly, check the operation
of the pump by manually raising the automatic
float switch. If the sump pump is operable, but
will not drain properly, check all drain lines for
debris and clean as needed. See your Silverton
dealer for further inspection and repair if the

TRIM TAB
SYSTEM
The Trim Tab System operates on DC electrical
power controlled by a breaker switch, located
on the AC/DC Electrical Panel (See AC/DC
Electrical Panel Layout on Page 163, which
illustrates the location of the breaker switch that
controls the Trim Tab System). Each trim tab
operates independently of each other and they
are controlled by separate rocker-type switches,
located on the Helm Switch Panel (See Console
Layout on Page 162, which illustrates the location of the trim tab switches). Each trim tab is
actuated by a hydraulic cylinder, which moves
them in an Up or Down position as determined
by depressing the rocker-type switches as follows:
________________
The purpose of the Trim Tab System on your
453 Motor Yacht is to assist in reaching planing speed as soon as possible and to maintain a
proper “running attitude” while in forward motion. “Running Attitude” is defined as the level
of the boat, both fore, aft, and athwartships,
while the vessel is underway. Your yacht, upon
reaching planing speed, should rise slightly in
the bow and should not list to either side for the
greatest stability and fuel economy. Your 453
Motor Yacht is equipped with two (2) Bennett
trim tabs, each measuring 12”x30”, which are
mounted on the bottom edge of the transom (See
photograph below, which illustrates the location
of the trim tabs).
• Depressing the TOP of the switch lowers the trim tab.
• Depressing the BOTTOM of the
switch raises the trim tab.
The Trim Tab system operates in the following
manner:
• The function of the trim tab is to redirect the
flow of water beyond the bottom of the transom.
This creates an upward pressure on the hull bottom at the transom, which results in lowering
the bow.
• When the Port trim tab is lowered, the Port
stern section is raised, which lowers the Starboard side of the bow.
• When the Starboard trim tab is lowered, the
Starboard stern section is raised, which lowers
the Port side of the bow.
• Both trim tabs should be lowered/raised as
needed to maintain a proper “Running Attitude”.
121
REFER TO THE BENNETT TRIM TAB MANUAL INCLUDED WITH YOUR OWNER’S
PACKET FOR TECHNICAL INFORMATION CONCERNING THE OPERATION
AND MAINTENANCE OF THE TRIM TAB
SYSTEM.
Operation of the Trim Tab
System may require practice to attain a level
of proficiency. DO NOT operate either trim tab
to its extreme lowered position suddenly. This
may cause the bow to lower to an unsafe position
while heading into or away from waves, which
may cause “swamping” of your yacht, resulting
in possible injury or death. DO operate the trim
tab switches with short “bursts” until the desired
“Running Attitude” is obtained.
Maintenance of the Trim Tab system is as follows:
• Silverton recommends painting the trim tabs
with good quality, anti-fouling bottom paint.
DO NOT paint any hinges of the moving parts
of the cylinders.
• To reduce the risk of electrolysis and galvanic
corrosion, Silverton recommends the installation
of sacrificial zinc anodes on the trim tab plates at
least once a year, preferably during preparation
for spring launch. DO NOT paint the sacrificial
zinc anodes.
• Periodically examine the trim tabs for accumulation of underwater growth and clean as
necessary.
• Periodically examine the trim tab pump and
hydraulic lines, which are located in the bilge
area, for leaks (See Mechanical Layout on Page
161, which illustrates the location of the trim tab
pump). Tighten connections if leaks are noted.
If the hydraulic lines appear worn or chafed,
contact your Silverton dealer for inspection and
replacement, if necessary.

WASHER /
DRYER
(OPTIONAL)
____________________
You may have purchased as an option with
your 453 Motor Yacht the optional Combo
- Matic 2000 Washer / Dryer system. This
system is located aft of the Forward V- Berth
in the Companionway. It operates on 110V
AC electrical power and receives its washing
water through the Fresh Water Supply System.
The photograph below illustrates the Washer /
Dryer system.
123
124
SEAKEY
SatCom SENDING UNIT
The SeaKey Satellite Communication System
is installed on your yacht at the factory. It is
comprised of the following items:
•
•
•
High Water Alarm Switch
SatCom Sending Unit
Dislay Control Unit
Your SeaKey System always has battery power
to it. This is a major advantage over the VHF
Radio, which may be accidentally turned off.
The SatCom Sending Unit is installed under the
helm on your yacht. This unit sends out a low
frequency signal to the satellite, which in turn
sends the signal to the recieving location. You
must know the location of the Sending Unit. If
anyone is standing in front of the Sending Unit,
they could block the signal from going to the
satellite. Refer to the SeaKey Owners Guide for
more information.
HIGH WATER ALARM SWITCH
DISPLAY CONTROL PANEL
Access to the High Water High Water Switch
is through the access panel in the forward part
of the engine room. Please be aware this Alarm
Switch is about 5” higher than the normal operating bilge switches that are installed on your
yacht by Silverton. Please also be advised that
the switch is only in the mid compartment.
Other compartments could flood first and the
switch would not be activated. The switch will
only be activated when the normal operating
bilge pumps have failed and cannot handle the
incoming water flow.
The Control Panel has many functions. Refer to
the SeaKey Owners Guide to understand all the
important features of the control panel.
Your SeaKey system draws its’ power from the
batteries in your yacht. If the batteries go dead,
or if the batteries are removed from the system,
the system will send a signal to the receiving
station. Before removing power form your system we recommend contacting SeaKey Member
Services for the proper procedures.

CLEANING
AND
MAINTENANCE
Wood
There are many wood surfaces in your 453 Motor Yacht, such as galley cabinets, entertainment
cabinets, and trim. Care and cleaning of the
wood surfaces is identical to the maintenance
of the wood surfaces in your home. Frequently
remove dust from the wood with a feather duster
or similar cleaning tool. Apply a good quality
furniture polish, such as Liquid Gold, to all
wood surfaces on a regular basis to maintain
their beauty and lustre.
________________
A periodic cleaning and maintenance schedule
of the interior and exterior surfaces of your 453
Motor Yacht is recommended. Not only will it
maintain your yacht in pristine condition, but it
will also result in a higher resale or trade-in value
when you decide to purchase another Silverton
yacht. A clean yacht is both pleasing to the eye
and a source of pride in ownership. Cleaning
and maintenance of your 453 Motor Yacht is
described in the following categories:
Nautolex (Vinyl)
Gently wash with a mild soap and water solution
and dry with a soft, lint-free cloth on a regular
basis. DO NOT wait for the vinyl surface to
appear soiled before you clean it, as stains
and ground-in surface dirt may be difficult to
remove.
• Interior Cleaning/Maintenance
• Exterior Cleaning/Maintenance
• Canvas Enclosure Cleaning/Maintenance
Interior
Cleaning/Maintenance
DO NOT use cleaning agents
containing bleach, as they will remove the color
tint from the vinyl surface, causing a blotching
appearance and will dry the material, resulting
in surface cracks.
There are several different types of surfaces
in the interior of your 453 Motor Yacht and
all require a different method of cleaning. The
surfaces and their respective cleaning and maintenance procedures are as follows:
Upholstery
Fiberglass
The upholstery in your 453 Motor Yacht is high
quality and stain resistant. Frequently vacuum
the upholstery to remove any dirt before it accumulates and becomes imbedded. Stains may
be removed by using a quality household stain
remover. Be certain to follow the manufacturer’s
directions concerning its use.
Wash with a mild soap and water solution. Thoroughly dry with a soft cloth and apply a coat of
good quality wax designed for marine use.
DO NOT use abrasive cleaning
agents on fiberglass surfaces, as they will scratch
and dull the finish.
125
Carpeting
Corian
The carpet in your 453 Motor Yacht is a high
quality nylon pile. Normal cleaning and maintenance is accomplished by vacuuming on a
frequent and regular basis. Refer to the carpet
manufacturer’s pamphlet included with your
owner’s packet for additional cleaning procedures, such as stain removal.
The galley and head counter tops and head sinks
are manufactured of Corian, which is a superior
quality, tough, scratch-resistant material. The
Corian surfaces in your 453 Motor Yacht are
a Matte/Satin finish and are easily cleaned and
maintained in the following manner:
Cleaning: Dirt and stains are removed by using
a soap and warm water solution. Tough stains
may be removed by using an ammonia-based
cleaning agent. Watermarks may be removed
simply by wiping the surface with a clean, damp
cloth and drying with a towel.
You may have chosen as an option at the time of
purchase of your 453 Motor Yacht, a “Central
Vac” vacuum cleaning system. Similar to the
system in your home, only a removable vacuum
hose with cleaning attachments is necessary to
vacuum any portion of the interior of your yacht.
The “Central Vac” system in your yacht is operated on the AC electrical system with a “Ground
Fault Interrupter” circuit for your protection.
The vacuum motor and canister (which stores
the vacuumed soil) are self-contained in one
unit and located slightly above the middle step
leading from the salon to the companionway.
(See photograph below, which illustrates the
location of the “Central Vac” system). Access to
the collection bag is gained through the lower
panel located on the face of vacuum unit. There
is one (1) vacuum hose outlet, which is located
on the face of the canister access panel. Refer to
the manufacturer’s pamphlet included with your
owner’s packet for specific directions concerning operation of the system.
Disinfecting: Occasionally wipe the surfaces
with a 50/50 water and bleach solution. Rinse
with warm water and dry with a towel.
Sink Cleaning and Disinfecting: General
cleaning of the Corian sinks is the same procedure as described above. For a more thorough
cleaning, occasionally fill the sink with a 50/50
water and bleach solution and let soak for fifteen
(15) minutes. As the solution drains, wash the
bottom and sides, rinse with warm water and
dry with a towel.
Cuts and Scratches: Cuts and scratches may be
removed from your Corian surfaces. Refer to
the manufacturer’s pamphlet included with your
Owner’s Packet for the proper procedure.
126
Exterior
Cleaning/Maintenance
on a regular basis. Thoroughly wash the hardware with a soap and warm water solution and
rinse with fresh water. Dry with a soft cloth to
remove any water stains. If discoloration or salt
deposits are not removed with normal washing,
a non-abrasive household cleaner or stainless
steel polishing powder may be used with a soft
bristle brush. Always scrub in the direction of
the polishing lines imbedded in the stainless steel
to avoid scratching the surface. For a superior
shine, wipe the stainless steel with a light coat of
kerosene, followed by a light coat of lemon oil.
The kerosene enhances the lustre and protects
the stainless steel and the lemon oil removes the
unpleasant kerosene odor. Be careful not to spill
or wipe kerosene on the fiberglass surfaces, as
it will remove the coat of wax.
The exterior surfaces of your 453 Motor Yacht
consist primarily of fiberglass, stainless steel,
aluminum, safety glass, acrylic plastic, and
anti-fouling bottom paint. As with the interior
surfaces, the exterior surfaces demand frequent
cleaning and maintenance and the respective
procedures are as follows:
Fiberglass
Wash with a mild soap and water solution, particularly if your yacht is used in salt or brackish
water. Always thoroughly wash your yacht after
each use in addition to a regular, periodic washing schedule. A more frequent washing schedule
may be required, depending on the environment
where your yacht is normally docked/moored.
A soft scrub brush may be used on the non-skid
surface areas. Thoroughly dry with a soft cloth
and apply a coat of good quality wax designed
for marine use, such as carnauba paste wax. DO
NOT apply wax to the non-skid surface areas,
as it will render them ineffective. If your boating season is year around, it is recommended a
coat of wax be applied every three (3) months. If
your boating season is restricted to the summer
months, it is recommended a coat of wax be applied prior to spring launch and again at the end
of the season prior to winter storage.
DO NOT use abrasive cleaning
agents or steel wool pads or brushes, as these
products may scratch and damage the stainless
steel finish.
Aluminum
The windshield and window frames on your 453
Motor Yacht are manufactured of aluminum,
unless you purchased, as an option, stainless
steel frames. The aluminum components are
cleaned and maintained in the same manner
as the components manufactured of stainless
steel.
DO NOT use kerosene or lemon
oil on any painted aluminum surfaces, as they
will soften and remove the paint.
DO NOT use abrasive cleaning
agents on fiberglass surfaces, as they will scratch
and dull the finish.
Stainless Steel
DO NOT use any abrasive
cleaning agents or steel wool products when
cleaning aluminum. Aluminum scratches very
easily and these products will scratch the surface.
The bow rail, aft deck rail, mooring cleats and
other hardware on your 453 Motor Yacht are
manufactured of quality 316 grade stainless
steel. Stainless steel will not rust under normal
conditions, but it must be properly maintained
127
Canvas Enclosure
(Optional)
Cleaning/Maintenance
Safety Glass
The windshield and windows on your 453 Motor
Yacht are manufactured of safety glass similar to
the safety glass found on your automobile. The
safety glass on your yacht is much heavier and
thicker than the glass on your automobile and
meets or exceeds all American Boat and Yacht
Council (ABYC) standards. The safety glass
may be cleaned with the same soap and warm
water solution used for cleaning the exterior
surfaces of your yacht and then dried with a soft
towel. For a thorough cleaning and to remove all
water stains, use a quality window cleaner, such
as Windex, and dry with a paper towel.
The canvas enclosure you purchased as an option
from your Silverton dealer consists of canvas
fabric, vinyl windows, and zippers. An aluminum tubular frame supports the enclosure and it
is secured to the bridge and deck with “snaps”.
Each of these components require a different
cleaning and maintenance procedure and they
are as follows:
Canvas Fabric
The canvas should be cleaned on a regular basis
before dirt, salt, and other deposits accumulate
and become imbedded in the fabric. The canvas
may be cleaned, without removal from your
yacht, while it is in the normal upright position.
Brush off any loose dirt and then rinse with fresh
water. Wash the fabric with a mild soap and
lukewarm (temperature less than 100° F) water
solution, rinse thoroughly with fresh water and
allow to air dry.
DO NOT use any abrasive
cleaning agents or abrasive cleaning cloths or
pads when cleaning safety glass surfaces, as they
will scratch the surface.
Acrylic Plastic
The venturi windshield, which is located on the
bridge of your 453 Motor Yacht, and the salon
entrance door, are manufactured of a tough
acrylic plastic. Clean these surfaces with a mild
soap and water solution or non-ammonia based
cleaner and dry with a soft cloth.
DO NOT use any cleaning
agents containing detergent, as they will remove
the protective coating, resulting in stiffness and
eventual cracking of the fabric.
DO NOT use any abrasive
cleaning agents or abrasive cleaning cloths or
pads when cleaning acrylic plastic surfaces, as
they will scratch the surface.
DO NOT dry the canvas fabric
by any means other than air-drying. Use of heated drying apparatus, such as a hair dryer, will
result in stiffness and cracking of the material.
128
Vinyl Windows
Stainless Steel Tubular Frame
The vinyl windows in your enclosure should be
cleaned on a frequent basis to extend their life
and maintain clarity. Rinse off any loose dirt
with fresh water and wash with a mild soap and
cool water solution. After washing, rinse with
fresh water and dry with a soft cloth.
The upper portion of your canvas enclosure is
supported by a tubular stainless steel frame. The
frame is secured by stainless steel pins placed
in brackets that are permanently mounted on
the fiberglass surface at various locations on
the bridge and deck. The stainless steel frame
is cleaned and maintained in the same manner
as the aluminum components on your yacht as
previously described.
DO NOT use any abrasive
cleaning agents or brushes when cleaning your
vinyl windows, as they will scratch the material,
resulting in poor clarity.
DO NOT use kerosene or lemon
oil on the stainless steel frame, as it will stain
the canvas fabric. A small amount of lubricant,
such as CRC, may be used to lubricate the stainless steel pins.
DO NOT fold the vinyl windows after removing them from the enclosure.
Roll them prior to placing them in storage. Folding the vinyl windows will cause creases and
eventual cracking. If you anticipate long-term
storage, place a soft cloth over the vinyl window
and roll the window with the cloth in place. The
cloth barrier will prevent the vinyl from sticking
to itself, particularly during warm weather.
Two-Piece “Snaps”
The lower portion of your canvas enclosure is
secured to the bridge and deck by two-piece
“snaps”, which are manufactured of chromeplated brass. The female portion is permanently
secured in the lower seam of the canvas and the
male portion is permanently secured into the
fiberglass surface of the bridge and deck. Frequently examine the snaps for the presence of
dirt and remove with a soap and water solution
and rinse with fresh water. Periodically lubricate
the female portion with a small amount of lubricant, such as Vaseline Petroleum Jelly.
Zippers
The various sections of your canvas enclosure
are secured together with zippers to permit easy
removal of any or all sections without the cumbersome weight or size of the entire unit. The
zippers are manufactured of high impact plastic
coated stainless steel and have large teeth for
smooth operation. They should be washed while
you are washing the canvas and then periodically
lubricated by rubbing a candle on the zipper in
the closed position and then opening and closing
several times to distribute the wax lubricant.
129
WINTERIZATION
AND
STORAGE
may become apparent during the winterization
process. Make arrangements with your Silverton
dealer to have the repairs completed.
________________
Cleaning and Preparation For Storage
In most cases, the reason for storage of your
yacht is winter lay-up. The information contained in this section is a general guide. Your
Silverton dealer or a competent boatyard should
prepare your yacht for winter storage.
Thoroughly clean the hull immediately
after removing the yacht from the water. Pressure wash the bottom, if possible, to remove all
marine growth. If pressure washing is not possible, thoroughly scrub the hull bottom. Marine
growth is much easier to remove while it is still
wet.
If you are removing your yacht from the water
for another reason, use the information in this
section as a guideline. Following the procedures
in this section will help extend the life of your
yacht and its equipment and simplifies re-commissioning in the spring.
Thoroughly clean the remainder of the
hull and the deck. Silverton recommends a coat
of wax be applied to the hull above the waterline
and to the deck for added winter protection.
Indoor storage is beneficial if you are storing
your yacht in a climate that produces ice and
snow. The storage building should be adequately
ventilated and not tightly closed. Ventilation,
both around and throughout the yacht, is very
important to help prevent the growth of mold
and mildew.
Apply rust inhibitor, such as CRC, to all
metal parts.
Thoroughly clean the inside of all hull
openings, thru-hull fittings and filtration screens
(See Thru-hull Layout on Page 157 and 158,
which illustrates the location of the thru-hull
fittings. See Mechanical Layout on Page 161,
which illustrates the location of the seawater
intake valves). Inspect the hull and underwater
gear for signs of wear, deterioration, or damage
and repair, if possible, before covering and storing your yacht.
If you use outdoor storage facilities, cover
your yacht with a cover having provisions for
ventilation to keep the yacht from “sweating”.
Building a frame over the boat to support the
cover will allow the passage of air around the
yacht. The frame should be a few inches wider
than the yacht so the cover will extend beyond
the rubrail. The frame should also support the
center of the cover and cause it to rise in a slight
“teepee” position to allow for water runoff.
Fill the fuel tanks to prevent condensation and add a good quality fuel preservative
(Refer to the fuel preservative manufacturer’s
recommendation for the proper ratio).
NOTE: DO NOT seal the cabin tightly to allow
proper ventilation throughout.
IMPORTANT: DO NOT overfill the fuel tanks
so fuel flows from the vent(s). Allow sufficient
room in the tanks for fuel to expand.
Before preparing your yacht for winter storage,
thoroughly check the condition of the yacht and
its systems and equipment. Note any repairs that
may be needed. The need for additional repairs
Prepare the engines for storage. Refer to
the engine manual for winterization and storage
procedures.
130
Prepare the generator and air conditioners (if so equipped) for storage. Refer to the
generator manual and the air conditioner manual,
included with your owner’s packet, for the
proper winterization and storage procedures.
Turn OFF the fresh water pump and reconnect the inlet hose to the fresh water tank.
Pour non-toxic anti-freeze into all sink
and shower drains until the liquid is discharged
overboard.
Draining Your Yacht
Alternate procedure for draining and winterizing
the fresh water system is as follows:
Your yacht has drain plugs for draining water
from the bilge (See Mechanical Layout on
Page 161, which illustrates the location of the
garboard drain plugs). Some compartments in
the bilge may not drain completely due to the
position of the yacht. Pump these compartments
out with a portable pump and then use a sponge
to remove all remaining water.
Drain all water from the fresh water
tank.
Drain all water from the water heater.
Remove hose from the input side of
the fresh water pump and allow to completely
drain.
The procedure for draining and winterizing the
fresh water system is as follows:
Remove hose from the output side of the
fresh water pump and turn ON all faucets.
Drain the fresh water supply tank by
opening the hot and cold faucets in the galley
for ten (10) minute intervals until the tank is
empty.
Blow compressed air (15-20 lbs. psi)
through the output hose until all water stops
flowing from the faucets.
Open all faucets in the galley, both showers, both head sinks, and the exterior cockpit
shower.
Leave water lines at the fresh water pump
disconnected to allow any trapped water vapor
to drain and evaporate.
Remove the fresh water filter bowl and
strainer. Clean, dry, and replace strainer bowl.
The procedure for draining and winterizing the
marine sanitation system is as follows:
Drain the water heater and remove the
cold water intake hose and hot water output hose
and hook them together.
Drain all water lines into the waste holding tank. Continue to flush fresh water into the
waste holding tank and pump out into an approved waste facility until thoroughly clean.
Remove the inlet hose from the fresh
water tank (See Mechanical Layout on Page
161, which illustrates the location of the fresh
water tank) and insert it into a container of nontoxic, fresh water anti-freeze. Turn the fresh
water pump ON and starting at the farthest
faucet from the pump, turn ON all faucets until
the anti-freeze flows out.
Add non-toxic, freshwater anti-freeze to
the waste holding tank by flushing through the
toilet.
Run the macerator pump to allow antifreeze to flow through the pump and the input/
output lines.
131
Remove the drain plug from the macerator seacock while the valve is closed and allow
the line to drain. Replace the drain plug.
IMPORTANT: DO NOT store batteries on a
concrete surface, such as a garage floor, as they
will tend to discharge.
Thoroughly clean the toilet and leave the
bowl exposed to prevent mildew.
Keep batteries fully charged during
storage. Periodic charging (once a month) with
a battery charger set on a low amperage charge
is recommended. Check the battery electrolyte
levels regularly. Add electrolyte, if needed.
Remove all seacock and strainer drain
plugs to prevent from freezing. Close all seacocks.
REFER TO THE BATTERY LITERATURE INCLUDED WITH YOUR OWNER’S PACKET
FOR ADDITIONAL INFORMATION CONCERNING THE CARE AND STORAGE OF
YOUR BATTERIES.

Interior Preparation
The procedure for preparing the interior of your
yacht for winter storage is as follows:
Strainers
•
•
•
•
Remove all items that will hold moisture
(towels, PFD’s, blankets, clothing, canvas, etc.)
from the interior of the yacht to prevent mold
and mildew formation.
Engines

Generator (if equipped)
Air Conditioners (if equipped)
Remove all electronic equipment and
items of value that are detachable.
Battery Storage
Remove all garbage and trash.
The procedure for battery winterization and
storage is as follows:
Thoroughly clean the interior of your
yacht. Clean all cabinets, drawers and cupboards. Allow the cabin area to air dry for at
least one day, if possible.
Turn battery switch to OFF.
Remove engine batteries and generator
battery (if so equipped) from their respective
compartments (See Mechanical Layout on Page
161, which illustrates the location of the engine
and generator batteries).
Stand or prop up all mattresses and cushions that are to remain on board during storage
to allow air circulation around them.
Place Mildew Pacs in various locations
within the interior of your yacht to help prevent
mold and mildew formation during storage
(Refer to the manufacturer’s recommendation
for the quantity and location required).
Place batteries on a wooden pallet or
bench and store in an area where temperatures
remain above freezing.
132
Lifting Your Yacht
When lifting the yacht, keep the bow
higher than the stern so the engine and generator (if so equipped) exhaust lines can drain. This
will prevent water from flowing forward through
the manifold and into the engine itself, where it
may become trapped.
The following are guidelines that will help prevent damage to your yacht as it is being lifted:
Never lift the yacht with a greater than
normal accumulation of water in the bilge. All
tanks containing fresh water should be empty.
Always keep the bow higher
than the stern every time the yacht is lifted. DO
NOT lift the stern higher than the bow at any
time as this may cause water to enter the engines.
Engine failure is possible if water enters the engine cylinders. The water can cause “hydrostatic
lock” and bend the piston rods. “Hydrostatic
lock” is a situation where the piston cannot travel
to its full upward position due to the presence of
a liquid above the piston and extreme pressure is
forced downward as the piston moves upward.
Even a small quantity of water can cause rust or
other internal engine damage.
Place lifting slings where indicated by
the sling tab labels on the gunwales (See Thruhull Locations Layout-Port and Starboard on
Page ?, which illustrates the location of the sling
tab locations). Avoid placing slings where they
may lift the propeller shaft or other underwater
fittings. Padding, placed under the slings at the
chine corners, will help to keep pressure to a
minimum at this location.
Disconnect the propeller shafts at the
transmissions to prevent damage to the transmissions and shafts.
NOTE: Silverton recommends an optional storage cradle with the purchase of your yacht. The
cradle is factory made to conform to the bottom
of your yacht for safe storage and minimizes the
risk of hull distortion.
Use wide, flat, lifting slings made of
belting and spreader bars long enough to keep
pressure off of the gunwales.
DO NOT use slings made
of cable. Pressure caused by the slings on the
gunwales can cause severe gelcoat crazing or
more serious hull damage. The spreader bar at
each lifting sling should be at least as long as
the distance across the widest point the sling
surrounds.
If a marine railway or platform hoist is
being used, locate and adjust the blocking to
distribute the weight over several areas. The
weight borne by the keel must not be so great as
to cause crushing or distortion of the member.
133
134
OPERATING
YOUR
YACHT
Is your safety equipment in operable
condition and accessible, if needed?
Has your Silverton dealer reviewed the
operation of your yacht and its systems with
you?
________________
Most people who purchase a Silverton yacht
have boat handling knowledge and experience
with other types of vessels. This section of the
Owner’s Manual provides basic information
concerning the safe operation of your yacht
and is a review of the information contained
in each of the “Systems Sections”. Be certain
to read and have a thorough understanding of
all systems described in this Owner’s Manual
BEFORE you operate your yacht. Even if you
are an experienced yachtsman, you can benefit
from reviewing the information contained in
this section.
Has your Silverton dealer answered all
of your questions concerning the operation of
your yacht and all of its systems?
If you have completed the above preliminary
steps, you are ready to take your first cruise. Before you depart, give some thought to the cruise
itself. Choose a calm day, if possible, and take
only those people who will be members of your
regular crew. Leave guests on shore, so that you
are able to concentrate on learning as much as
possible about your new Silverton yacht without
unnecessary distractions.
The first cruise on your new Silverton yacht
should be a time for you to become acquainted
with the vessel. Before you depart on your first
cruise, you should be able to answer YES to the
following questions:
Prior to your initial or first seasonal engine
startup, follow the below listed procedures:
Has your Silverton dealer completed the
“Pre-Delivery Service Inspection”?
Be certain all electrical circuit breaker
switches are turned OFF.
Have you and your Silverton dealer
signed the “Pre-Delivery Service Record”?
Enter the engine compartment access use
your sense of smell to detect any fuel fumes.
Have you completed and mailed all warranty registration cards?
If ANY fuel fumes are detected:
Engine Startup Preparation
Evacuate your yacht IMMEDIATELY.
Have your read and do you have a complete understanding of this Owner’s Manual and
the O.E.M. Manuals included with your owner’s
packet?
Notify the dockmaster.
Open all hatches, doors, and windows to
provide natural ventilation.
Does your yacht’s safety equipment
comply with all United States Coast Guard and
local regulations?
Have a qualified marine technician examine your yacht immediately to determine the
source of the fuel fumes.
135
If a leak is detected, have it repaired as
soon as possible by a competent technician.
Check coolant. If coolant is low, refer
to the Engine Manual for proper filling instructions.
If you detect any fuel fumes, open all
hatches, doors, and windows to ventilate your
yacht.
Remove raw water strainer cap and
check for debris. Remove any debris noted.
Visually examine the engines and generator for any oil leaks. If leaks are noted, have
them repaired by a competent technician.
Open both raw water intake valves. The
valves are in the open position when the handle
is parallel to the valve body.
Examine the bilge area for water accumulation. Remove excess water and locate the
source of the water. Remember, a small quantity
of water in your bilge is normal.
If your yacht is equipped with a generator, be certain there is no debris in the water
strainer. Remove any debris noted.
Open the fuel shutoff valves for the
engines and generator. The valve is in the open
position when the handle is parallel to the valve
body.
Turn ON the following switches:
Both battery switches.
DC Electrical Panel main breaker
switch.
Check the oil level in the trim tab reservoir and be certain the level is between the
FULL and ADD marks.
Helm electronics breaker switch.
Both engine controls breakers.
Helm accessory breaker switch.
Visually examine the fire extinguisher
system in the engine compartment to be certain
it has not been discharged.
Check the engine oil level. Refer to the
Engine Manual for specific instructions concerning the proper oil level and filling procedure.
Check the transmission fluid level. If the
level is low, add fluid, but DO NOT overfill. Be
certain the fluid level is below the full mark on
the dipstick when the transmission is cold. The
fluid will expand as it warms and will overflow
if the level is too high.
Check the generator oil level. Refer to
the Generator Manual for specific instructions
concerning the proper oil level and filling procedure.
136
Engine Startup
engine using the “Parallel Start” switch, which
draws power from both batteries. Release the
parallel start switch immediately after the engine
starts.
IMPORTANT: Always be very careful when
starting your engines. Use common sense and
good judgement. Turn OFF the engine(s) immediately if you observe any unsafe operating
condition.
DO NOT continue to depress
the “Parallel Start Switch” after the engine
has started. Damage to the alternator(s) may
result.
The below listed procedures should be followed
when starting your engines:
Place shift control levers in the neutral
position.
Be certain the oil pressure is between 35
and 70 psi . If the oil pressure is low, turn OFF
the respective engine immediately.
Turn ignition switch to ON, but not to
START. Be certain the engine oil pressure alarm
sounds and the Automatic Fire Extinguisher
System indicator light is ON.
Allow the engines to operate at the
recommended RPM’s as specified in the Engine Manual until they reach normal operating
temperature. Normal operating temperature for
gasoline engines equipped with a fresh water
cooling system is 170° F and if equipped with a

170° F and 190° F.
Push button marked START and hold
until the engine starts. Release the starter button
immediately after the engine starts. If the starter
motor does not operate when you push the starter
button, you may be out of neutral. Check the
Shift/Throttle control unit to make sure you are
in neutral.
Check for water discharging from the
exhaust outlets. The presence of water indicates
water circulation in the exhaust cooling system.
Water should discharge through the exhaust
outlets immediately after the engine starts.
If the engine fails to start within
thirty (30) seconds, release the starter button.
Allow the starter motor to cool for at least sixty
(60) seconds and then try again to start the engine. Prolonged starting attempts may result in
starter motor overheating and damage.
After engines reach their normal operating temperature, increase the RPM’s to 2000. Be
certain the voltmeters read between 13 and 14.5
volts.
Failure to release the starter
button from the START position after the engine
starts may result in serious damage to the starter
motor and/or engine flywheel.
Visually inspect the exhaust system for
leaks. If any leaks are detected, immediately
turn OFF the respective engine and contact a
competent technician for repair.
If one of the batteries is not sufficiently
charged to start the engine, start the engine with
the fully charged battery first. Start the other
Check the transmission fluid level after
the engine is warm. The transmission should
be in neutral and the engines operating at idle

Transmissions: Check that both transmissions
shift smoothly and positively.
speed. Transmission fluid should be at or slightly
below the FULL mark on the dipstick. Add
transmission fluid if the level is low, but DO
NOT overfill.
Trim Tabs: Check that the trim tabs operate
properly and are responsive to your use of the
controls.
Shakedown Cruise
After completing your shakedown cruise, recheck all fluid levels. Check all drive belts for
the proper tension. Generally examine all components to be certain they did not loosen during
the cruise. Make all adjustments as necessary.
Silverton recommends a shakedown cruise after the initial or seasonal startup. This will test
the engines and various systems under normal
operating conditions. Note any condition that
does not meet normal operating performance
standards. Repair any condition noted as soon
as possible.
DO NOT remove the cooling
system filler cap when the engine is hot. Allow
the engine to cool and then remove the pressure
cap slowly, allowing the pressure to vent. Hot
coolant, under pressure, may discharge violently
and result in serious personal injury and burns.
IMPORTANT: Before fueling your yacht, be
certain you have read and have a thorough understanding of the information contained in the
“Fuel System” Section of this Owner’s Manual.
It contains valuable information and cautions for
your safety and the safety of your passengers.
Getting Underway
Check the following for proper operation during
your shakedown cruise:
After your engines have warmed to normal
operating temperature, you are ready to depart
your dock/mooring. Check the wind, tide, and
current to determine the best way to safely maneuver your yacht away from the dock. Cast off
all mooring lines.
Air Conditioner(s): If your yacht is equipped
with an air conditioning system, be certain each
air conditioner is operating properly.
Engines: Check for fuel, oil and water leaks.
Check the exhaust system for leaks.
Shift the transmissions into forward or reverse,
depending on which way you want to depart your
dock. Your engines should be at idle speed while
departing your dock and power should only be
used if necessary for control of your yacht.
Once your yacht has departed the dock and is in
open water, accelerate to cruising speed (RPM’s)
as recommended in the Engine Manual.
Generator: If your yacht is equipped with a generator, be certain it starts and operates properly.
Check for oil, water and exhaust system leaks.
Instruments: Be certain that all instruments
operate properly and provide normal readings.
Steering: Check that the steering system is
responsive.
Be certain to follow all safety precautions as
mentioned in the “Boating Safety” Section
of this Owner’s Manual while operating your
yacht.
Shift and Throttle Controls: Be certain the
shift and throttle controls operate properly and
are in the proper adjustment.
138
Daily Engine Shutdown
After you have completed your cruise and
secured your yacht to the dock, shut down the
engines in the following manner:
Reduce engine speed to idle.
Place transmission controls in neutral.
Allow engines to operate at idle speed
for several minutes.
Turn ignition switches to the OFF position to shut down the engines.
Operate the bilge blower motors for
several minutes to circulate fresh air through
the engine compartment.
Turn OFF battery switches.

FIFTEEN WAYS
TO REDUCE
FUEL CONSUMPTION
9.
Load your yacht correctly. DO NOT put
all of the heavy gear, such as anchors, chain,
canned goods, and spare parts exclusively in
either the bow or stern. Heavy items should be
placed amidships where they will not affect the
trim and plane of the yacht.
________________
1.
Keep the bottom of your yacht clean. A
fouled bottom can increase drag up to 10% or
more. A 10% increase in drag is equivalent to a
10% increase in fuel consumption.
10.
Check the drive train. An inboard engine
that is improperly aligned can cost you money.
Check to see if the transmission has sufficient
fluid (too little increases friction), or if a bent
rudder or propeller are robbing you of economy.
Be certain the rudders are properly aligned.
2.
DO NOT idle your engines needlessly.
Depart your dock/mooring after warm-up.
3.
Watch your trim. A well balanced yacht
gets on plane faster, handles better, and runs with
less surface contact.
11.
Check the engine cylinder compression.
Low compression indicates worn piston rings or
valves which will consume oil and reduce engine
power.
4.
Navigate better. By plotting courses to
your destination instead of just waiting for them
to appear somewhere in front of you, you can
eliminate miles off of your distance and gallons
off of your fuel consumption.
12.
Check the engine idle speed. For the
times it is necessary to operate at idle speed, be
certain the engine is not running too fast and
using unnecessary fuel.
5.
Know your fuel consumption. By plotting a fuel consumption/RPM curve for your
yacht, you will probably find that reducing your
engines’ RPM’s 10% can often reduce your fuel
consumption 30% with only a slight reduction
in speed.
13.
Check the engine operating temperature.
Compare your normal operating temperature
with the range specified in the Engine Manual
and in this Owner’s Manual. An overheating
engine will cause excessive wear and will be
less efficient.
6.
Remove extra weight. If you are not going to use it, do not carry it aboard. Any extra
weight requires more fuel to move your yacht.
Do not just stop at the lockers. Remember that
water weighs 64 pounds per cubic foot, so keep
the bilge areas dry.
14.
Keep the engine and transmission oil
clean. Dirty oil causes varnish to form on the
moving surfaces of the engine/transmission.
Varnish can cut into the piston ring seal and
contribute to fuel waste. Varnish will cause the
transmission to “slip”.
7.
Improve your yacht handling ability. DO
NOT let the yacht labor along below a planing attitude. This is the absolute peak of fuel
waste.
15.
Keep hot water use to a minimum. The
less hot water you use, the less time your generator will have to run, resulting in lower fuel
consumption.
8.
Purchase good quality fuel. Be certain
you are using the correct fuel for your engine.
