CARBON MONOXIDE "CO"I LOW-CO· GENERATORS
IMPORTANT INFORMATION
DESCRIPTION
In a closed space, such as the engine compartment, the boat,
or underneath a stem swim platform, concentrations will
potentially rise to the undiluted level emanating from the
exhaust system due to a lack of fresh air to dilute the exhaust
gas. Therefore, one should never rely on dilution of the
exhaust to provide a margin of safety.
Carbon monoxide "CO" is a component of engine exhaust. It
is a colorless, tasteless, odorless, lighter than air poisonous
gas that can kill you without any warning. CO poisoning is
one of the major safety risks associated with boating. It is a
threat that must not be underestimated.
Westerbeke Low-CO generators are designed to dramatically_
reduce normal levels of CO in the engine exhaust.
Several standards for CO have been published, expressed in
parts per miliion "ppm" and hours of exposure:

. Westerbeke Low-CO generators achieve reduction of typical
CO by precise control of the engine's air/fuel ratio coupled
with-after treatment of the exhaust in a special catalyst. CO
emissions are not the sa~e for every model because each
engine is different. Also, certain fuel system components
are .c.ommonized across several engine models being
ad~quate for some and extra adequate for others, thus
producing different CO levels for different models.
The fuel system which accomplishes the required precise
air/fuel ratio control is comprised of many different
components: purc~ased sub-assemblies, machined castings,
sensors, electronics 'and others. Because of the extreme level
of CO reduction, any variability in the functioning of any
these components can and will cause variability of the CO
output.
CO concentration also varies with load. Usually, but not
always, the worst case CO concentration occurs at maximum
load.

IMMEDIATELY' DANGEROUS TO LIFE AND HEALTH.
INSPECTION
.A city in California characterizes the effect of CO ,
concentration this way:
The catalyst is critical to optimizing CO levels. Any water
intrusion into the engine's exhaust system will likely quickly
compromise the proper operation of the catalyst.
Westerbeke'snd exhaust system installation instructions dated
May 2004 2 Edition must be adhered to.
NOTE: Water intrusion is not a product defect and is not
covered under warranty, neither Westerbeke s normal
product warranty nor the emissions .specific warranty
mandated by various regulating authorities such as EPA
andCARB.
Maintenance of any components affecting the flow of air into
the engine or the flow of fuel to the engine is critically
important. Fuel filters, air filters, flame arrester screens
MUST be properly maintained.
Inspection of the catalyst at the prescribed intervals is
critically important. The exhaust elbow is removed by
loosening the metal clamp to provide a view of the output
surface of the catalyst. Any visual irregularity of the nonnal
flush, honeycomb appear~ce is most likely a result of water
intrusion. The cause of the irregularity must be identified and
addressed. If there is irregularity, the catalyst and sealing
gasket must be replaced. The water injected exhaust elbow
casting must be inspected also for corrosion and replaced as
needed. Upon careful reassembly of the catalyst, new sealing
gasket, and exhau~t elbow, check for the presence of CO
while the engine is running. This must be performed with a
CO analyzer.

Responses
Permissible exposure level, no
apparent toxic symptoms.
No poisoning for long period.
Allowable for several hours.
Should not be exposed above
this level for any period of
time. A possible mild frontal
headache in two to three hours.
Even though Westerbeke Low-CO generators are designed
to reduce normal levels of CO in the engine exhaust
dramatically, an exhaust leak of untreated exhaust would be
extremely dangerous. For this reason it is extremely important
to install a CO detector near the generatoP--afld to be sure it is
always turned ON and FUNCTIONING properly. If this
d~tector sounds, do not turn it off, assuming it is a false signal.
You can not taste, smell, or otherwise detect CO. Leave the
::(lefector on, turn off all engines and generators, evacuate the
boat leaving ports and hatches open, and seek professional
h~lp.
As soon as CO leaves the exhaust outlet, the level is subject
to dilution in the open air. The closer a person is to the
exhaust outlet, the higher the concentration of CO.

CARBON MONOXIDE "CO"I LOW-CO GENERATORS
IMPORTANT INFORMATION
Whenever taking the time to verify proper co levels from the
exhaust with a co analyzer, always take theopportunity to
use the analyzer to "sniff' around the engine looking for CO
from exhaust leaks. Pay close attention to the connection of
the cylinder block to the sump plate, the sump plated to the
water injected exhaust elbow casting and all subsequent
downstream exhaust components and hoses and connection
points. Remember, exhaust gas that has not yet passed
through the catalyst is raw exhaust, untreated exhaust gas and
is very high in co content.
Catalyst performance will degrade over time. As the
generator accumulates operating hours, CO concentrations
will increase. The catalyst must be replaced every 2,000
hours of engine operation.
Verification of satisfactory CO levels must be done
seasonally or each 500 hours (which ever occurs first).
Verification involves actual sampling of exhaust gas with an
appropriate CO analyzer.
There are two locations where exhaust gas can be sampled.
Dry, but hot, exhaust gas can be sampled at the 1I8NPT
plugged opening on the top of the water injected exhaust
elbow's casting. Measurements at this location may not be
practical in all instances due to the high exhaust temperature,
temperature limits of the analyzer, safety concerns over
temperatures involved or the possibility of high levels of CO.
The other location is the boat's exhaust outlet, which .
contains entrained cooling water (except dry stack exhaust
systems). Only analyzers with probes should be used at this
location and it is critical that the probe not ingest water.
Probe-type analyzers have an air pump drawing a gas sample
through the probe. As a result, they tend to ingest water when
it is present. Be sure to aim the probe downwards with the
opening pointed in the direction of the water flow and just
out of the flow. Position the analyzer as high as possible with
the tubing leading to the probe running continuously downhill. Observe the usually translucent tubing between the
probe and the analyzer and be sure no water is being
ingested. If any water is ingested into the analyzer, it must be
repaired or replaced and recalibrated.
Analyzers usually require periodic calibration. Follow the
instructions that come with the analyzer very carefully
regarding calibration.
The following are manufacturers that offer CO analyzers:
Extech, TIP, Testo, TSI, Bacharach, Fluke, Monoxor, Fyrite,
Zellwgwer Analytics, Industrial Scientific Corp, GFG, TPI,
Teledyne and others. Westerbeke recommends analyzers with
a probe connected to the' analyzer by a length of transparent
tubing. They are slightly more expensive than those with the
sensor built into one end of the analyzer, but they allow you
to sample the exhaust coming out of the boat's exhaust outlet.
When measuring CO at the exhaust outlet be aware of the
ambient CO level by also measuring CO away from and
upwind of the exhaust outlet, especially in marinas. the CO
level at the exhaust will be influenced upwards by the
ambient level.
For changing the exhaust catalyst and measuring the
exhaust back pressure, refer to the Table of Contents.

vi
INSTALLATION
When installing WESTERBEKE engines and generators it is important that strict
attention be paid to the following information:
CODES AND REGULATIONS
Strict federal regulations, ABYC guidelines, and safety codes must be complied with
when installing engines and generators in a marine environment.
SIPHON-BREAK
For installations where the exhaust manifold/water injected exhaust elbow is close to
or will be below the vessel's waterline, provisions must be made to install a siphonbreak: in the raw water supply hose to the exhaust elbow. This hose must be looped a
minimum of 20" above the vessel's waterline. Failure to use a siphon-break when
the exhaust manifold injection port is at or below the load waterline will result in
raw water damage to the engine and possible flooding of the boat.
If you have any doubt about the position of the water-injected exhaust elbow relative
to the vessel's waterline under the vessel's various operating conditions, install a
siphon-break.
NOTE: A siphon-break requires periodic inspection and cleaning to ensure proper
operation. Failure to properly maintain a siphon-break can result in catastrophic
engine damage. Consult the siphon-break manufacturer for proper maintenance.
EXHAUST SYSTEM
The exhaust system's hose MUST be certified for marine use. Corrugated Marine
Exhaust Hose is recommended. The use of this type of hose allows for extreme bends
and turns without the need of additiinal fitting and clamps to accomplish these bends
and turns .In this regard, a single length of corrugated exhaust hose can be used. The
system MUST be designed to prevent the entry of water into the exhaust system
under any sea conditions and at any angle of vessels heal.
A detailed Marine Installation Manual covering gasoline and diesel,
engines and generators, is supplied with each unit. Apdf is available
to download from our website at www.westerbeke.com.

INTRODUCTION
ORDERING PARTS
PROTECTING YOUR INVESTMENT
Whenever replacement parts are needed, always provide the
generator and engine model and serial numbers. In addition,
include a complete part description and part number for each
part needed (see the separately furnished Parts Catalog).
Also insist upon WESTERBEKE packaged parts because
will fit or generic parts are frequently not made to the same
specifications as original equipment.
Care at the factory during assembly and thorough testing
have resulted in a WESTERBEKE generator capable of
many thousands of hours of dependable service. However the
manufacturer cannot control how or where the generator is
installed in the vessel or the manner in which the unit is
operated and serviced in the field. This is up to the
buyer/owner-operator.
NOTES, CAUTIONS AND WARNINGS
NOTE: Seven important steps to ensure long generator life:
As this manual takes you through the operating procedures,
maintenance schedules, and troubleshooting of your
generator, critical information will be highlighted by
NOTES, CAUTIONS, and WARNINGS. An explanation
follows:
• Proper engine and generator installation.
• An efficient well-designed exhaust system that includes
an anti-siphon break to prevent water from entering t.'ie
engine.
• Changing the engine oil and oil filters every 100 operating hours.
NOTE: An operating procedure essential to note.
A
• Proper maintenance of all engine and generator components according to the maintenance schedule in this
manual.
CAUTION: Procedures. which if not strictly
observed. can result in the damage or destruction of
the engine or generator.
A
• Use clean" unleadedfuel #89 octane. No higher than E10 ethanol blend.
• Winterize your engine according to the "Lay-up and
Recommissioning" section in this manual.
WARNING: Procedures. which if not properly
UNDERSTANDING THE GASOLINE GENERATOR
followed. can result in personal injury or loss of life.
The gasoline engine driving an AC generator is in many
ways similar to a gasoline automobile engine. The cylinders
are in-line, and the engine's cylinder head has an overhead
camshaft which is belt-driven. The engine incorporates a
pressure type lubrication system, and a water-cooled engine

NOTE: A carbon monoxide warning decal has been provided
by WESTERBEKE. Affix this decal in a visible location in the
engine room.
SPARES AND ACCESSORIES
Certain spare parts will be needed to support and maintain
your WESTERBEKE generator or engine when cruising (see
SUGGESTED SPARE PARTS). Often even simple items such
as proper fuel and oil filters can be difficult to obtain along
the way. WESTERBEKE will provide you with a suggested
spares and accessories brochure to assist you in preparing an
on-board inventory of the proper WESTERBEKE parts.
To a large degree, the generator's engine requires the same
preventive maintenance that is required of a gasoline
automobile engine. The most impOltant factors to the
generator's longevity are proper ventilation, maintenance of
the fuel system, ignition system, and cooling system.
CARBON MONOXIDE DETECTOR
WESTERBEKE recommends mounting a carbon monoxide
detector in the vessels living quarters. Carbon monoxide,
even in small amounts, is deadly.
The presence of carbon monoxide indicated an exhaust leak
from the engine or generator or from the exhaust
elbow/exhaust hose, or the fumes from a nearby vessel are
entering your boat.
If carbon monoxide is present, ventilate the area with clean
air and COlTect the problem immediately!

INSTALLATION
SIDE VIEW
RIGGING AND LIFTING
The engine/generator is fitted with lifting eyes. Attach
wire rope or chain slings capable of supporting the
engine/generators weight to the eyes and lift the engine/generator by means of tackle attached to these slings. The lifting
eyes have been designed to carry the full weight: auxiliary
slings are not necessary.
NOTE: Rigging work is best done by someone experienced
and competent in handling machinery.
LOCATION AND MOUNTING
A solid, level mounting platform is very important for the
proper operation of your generator. Select a location that will
allow adequate space on all sides for ventilation and servicing. Locate the generator away from living quarters, and
away from bilge splash and vapors.

INSTALLATION/EXHAUST SYSTEM
RAW WATER DISCHARGE
When the generators location is above the loaded water line
of the vessel during all attitudes of vessel operation, it is still
advisable to loop the raw water discharge hose at least 6 •
inches or more above the generator and then down to the
inlet connection on the water injected exhaust elbow.
The fresh water that flows thru the engine is cooled by a
continuous flow of raw water (via the heat exchanger). As
the raw water is discharged overboard, it is used to cool
the exhaust system.
RAW WATER SUPPLY HOSE (INSTALLING)
The raw water supply hose from the discharge conne.::tion on
the engines cooling system to the inlet connection of the
water injected exhaust elbow must be looped a minimum of
12 inches (30cm) above the vessels loaded water line. ,
On installations where the water injected exhaust is close to
or below the vessels loaded water line, provisions must be
made to install a syphon break in the raw water supply hose.
NOTE: Always use a quality hose with good wall integrity or
wire reinforced hose so it will maintain its shape when
looped and also provide proper mechanical support for the
hose.
EXHAUST ELBOW
The function of the syphon break is to stop the raw water
flow after the engine is shutdown. This flow, if not stopped,
will fill the exhaust system and possibly the engine as well.
The raw water supply hose must be looped well above the
loaded water line to allow the syphon break to function
during all attitudes of vessel operation to prevent syphoning
when the generator is not operating.

FUEL, ENGINE OIL AND ENGINE COOLANT
GASOLINE
ENGINE COOLANT
Use only unleaded gasoline with an octane rating of 89 or
higher. Higher octane is recommended. The use of lower
octane gasoline will adversly affect engine performance.
Ethanol blends must not exceed E-lO.
When fueling, follow U.S. Coats Guard Regulations. Close all
hatches and companionways to prevent fumes from entering
the vessel. Ventilate properly after fueling and before starting
the generator or main engines.
Use only clean fresh fuel! It is important to buy clean fuel, and
keep it clean. The best fuel can be rendered unsatisfactory by
careless handling or improper storage facilities. To assure that
the fuel going into the tank for your engine's daily use is clean
and pure, the following practice is advisable:
Purchase a well-known brand of fuel.
Install and regularly service a good, Coast Guard approved
metal bowl type filter/water separator between the fuel tank
and the engine. This filter rating must be 10 microns or
smaller.
Engine coolant a 50/50 mixture of antifreeze and distilled
water. This coolant allows the engine to run at its proper
temperature by transferring heat from the engine to the
coolant. It also lubricates and protects the cooling system
from rust and corrosion. A 50/50 mixture of antifreeze and
distilled water will protect the engine to _34°P (1.12°C).
PURCHASING ANTIFREEZE
Rather than preparing the mixture, WESTERBEKE
recommends buying the premixed antifreeze so that when
adding coolant, the mixture will always be correct.
ENGINE OIL
Use a heavy duty engine oil with an API classification of SJ,
SL, or SM. Change the engine oil and filter after an" initial
50 hours of break-in operation. Thenfolrow the oil change
interval as specified in the MAINTENANCE SCHEDULE
section of this manual and not be extended if synthetic oils
are used.
An oil viscosity of SAE 15W-40 is recommended for this
engine in all conditions and all seasons.
Westerbeke Corporation does not approve or disapprove the
use of synthetic oils. If synthetic oils are use, engine break-in
must be performed using conventional oil. Oil change
intervals must be as listed in the MAINTENANCE
SCHEDULE section of this manual and not be extended if
synthetic oils are used.
NOTE: The infonnation above supersedes all previous
statements regarding synthetic oil.
COOLANT RECOVERY TANK
A coolant recovery tank kit is supplied with each generator.
The purpose of this recovery tank is to allow for engine
coolant expansion and contraction during engine operation,
without the loss of coolant and without introducing air into
the cooling system.
NOTE: This coolant recovery tank, with its short length of
OVER-FILLING
hose, is best located at or above the cooling systems
pressurelfill cap.
CAUTION: The oil sump on this generator's engine can
unintentionally be over-filled!
After shutdown, the oil in the engines internal pasages can
linger and take a number of hours to drain back into the
sump. Allow at least a few hours for the oil to settle back
into the sump before checking the dipstick reading.
(Re-starting the engine is not a problem as the engine's
internal passages are well lubricated).
Over-filling the engine's sump will result in erratic operation,
andlor a smokey oil laden exhaust, hard starting and possible
no start.

PREPARATIONS FOR INITIAL START-UP
PRESTART INSPECTION
Before starting your generator set for the first time or after a
prolonged layoff, check the following items:
•
Make certain the cooling water thru-hull petcock is open.
•
Check the engine oil level. Add oil to maintain the level at
the full mark on the dipstick.
•
Check the fuel supply and examine the fuel filter/separator
bowls for contaminants.
•
Check the DC electrical system. Inspect wire connections
and battery cable connections.
•
Check load leads for correct connection as specified in the
wiring diagrams.
•
•
Examine air inlet and outlet for air flow obstructions.
Be sure no other generator or utility power is connected to
load lines.
•
Be sure that in power systems with a neutral line that the
neutral is properly grounded (or ungrounded) as the
system requires, and that the generator neutral is properly
connected to the load neutral. In single phase systems an
incomplete or open neutral can supply the wrong line-toneutral voltage on unbalanced loads.
•
Coolant
•
Check the coolant level in both the plastic coolant
recovery tank and at the filler neck opening on the unit.
NOTE: After the initial running of the generator, the air in
the engine's cooling system should be purged to the plastic
coolant recovery tank. After shutdown and as the engine
cools, coolant should be drawn back into the engine's
cooling system to replace the displaced air. Once cooled,
open the air bleed petcock on the engine's heat exchanger
to allow any air left in that area to be expelled. Thtm close
it. Open the pressure cap on the system filler neck and
ensure the system is completely full. Replace the cap· and
fill the plastic coolant recovery tank half way between MAX
and LOW.
Visually examine the unit. Look for loose or missing parts,
disconnect wires, unattached hoses, and check threaded
connections. Make sure there·is no leakage.
A CAUTION:. When starting the generator, it is
OIL FILL CAP
recommended that alMC loads, especially large motors,
be switched OFF until the engine has come up to speed
and starts to warm up. This precaution will prevent damage
caused by unanticipated operation of the AC machinery and
will prevent a cold engine from stalling.

SAFETY SHUTDOWN SENSORS AND SWITCHES
SAFETY SHUTDOWN SWITCH/SENSORS
Fuses
The engine is protected by four automatic shutdown circuits.
Should a shutdown occur, do not attempt to restart without
finding and correcting the cause. Refer to the heading
Engine starts, runs and then shuts down in the ENGINE
TROUBLESHOOTING section of this manual.
The following is a description of these automatic shutdown
circuits:
A FL-8A fuse located on the control panel protects the electrical wiring. If an amperage overload occurs, the fuse will
blow and shut the engine down.
A 20A ATM fuse protects the battery charging circuit. If this
fuse fails, the engine will continue to run but the battery will
not be charging.
~
~
High Exhaust Temperature Switch
ATM 20AFUSE
An exhaust temperature switch is located on the water
injected exhaust elbow. Normally closed contacts, this switch
will open and the ECU will interpret this as a high exhaust
temperature issue and de-energize the K2 and K3 relays,
stopping the generator.
Oil Pressure Sensor
An oil pressure sensor is located off the engines oil gallery.
Oil pressure on the sensor affects the DC voltage through the
sensor to the ECU. Should the voltage reach a preset value,
the ECU will interpret this as a low oil pressure issue and
open the K2 run relay, stopping the generator. The oil
pressure LED on the panel will illuminate.
. EXHAUST ElBOW
Main AC Circuit Breaker
The main circuit breaker at the control panel will
automatically disconnect the AC power if there is an
overload. This circuit breaker must be manually switched off
when servicing the engine/generator.
Oil Pressure Switch
The oil pressure switch sensors the engine's oil pressure. If
the oil pressure falls below 5 PSI, the switch will shut off the
fuel pump and the engine will shut down. Thw switch will
reset itself when the oil pressure is restored.

FUSE
Water Temperature Sensor
A water temperature sensor is located at the thermostat
housing. This resistance of the sensor changes as a function
of temperature. The ECU measures this resistance and
converts it to the corresponding engine coolant temperature.
When the coolant temperature reaches the warning threshold,
the CHECK ENGINE LED on the panel illuminates. If the
coolant temperature exceeds the shut-down threshold, the
ECU will open the K2 and K3 relays shutting down the
generator and the coolant temperature LED on the panel will
illuminate.
. MAIN AC CIRCUIT
BREAKER
Engine DC Circuit Breaker
The generator's engine DC circuit is protected by a rocker
type DC 20 amp breaker mounted on the control box. This
also serves as an Emergency Stop Switch. Excessive DC
current draw or DC electrical overload anywhere in the
instrument panel wiring or engine wiring will cause the
breaker to trip to the OFF position. In this event, the DC
power to the ECU will be interrupted, stopping the generator.
No panel LED will illuminate. Check and repair the source
of the problem. After repairing the fault, reset the breaker and
restart the generator. The DC breaker must be cycled OFF
then ON to clear any ECU shutdown from the ECU after the
fault situation has been repaired.
High/Low RPM Shutdown
The ECU monitors engine rpm via the MPU )Magnetic PickUp) that is mounted under the flywheel. When the engine
speed falls or rises to a pre-set rpm level, the ECU will shut
down the engine and the fault LED for speed will illuminate.

THE OIL FILTER
When removing the used oil filter, you may find it helpful to
ipunch a hole in the upper and lower portion of the old filter
to drain the oil into a container before removing it. This helps
to lessen spillage. An automotive filter wrench ~hould be
helpful in removing the old oil filter. Place some paper towels
and a plastic bag around the filter when unscrewing it to catch
any oil that's in the filter. Inspect the old oil filter as it is
removed to make sure that the rubber sealing gasket comes
. off with the old oil filter. If this rubber sealing gasket remains
sealed against the oil filter adapter, gently remove it. When
installing the new oil filter element, wipe the filter gasket's
sealing surface on the oil filter adapter free of oil and apply a
thin coat of clean engine oil to the rubber sealing gasket on
the oil filter. Screw the filter onto the threaded oil filter stub,
and tighten the filter firmly by hand.
NOTE: Use genuine WESTERBEKE oil filters. Genericfilters
are not recommended. '
A WARNING: Used engine oil contains harmful
REFILLING THE OIL SUMP
contaminants. Avoid prolonged skin contact. Clean skin
and nails thllroughly using soap and water. Launder or
discard clothing or rags containing used oil. Discard
used oil properly.
Add fresh oil through the valve cover. After refilling the oil,
run the engine for a few moments while checking the engine's
oil pressure. Make sure there is no leakage around the new
oil filter or from the oil drain system.
Always observe the old oil as it is removed. A yellow/gray
emulsion indicates the presence of water in the oil. Although
this condition is rare, it does require prompt attention to
prevent serious damage. Call a competent mechanic if water
is present in the oil. Water present in the oil can be the result
of a fault in the exhaust system attached to the engine and/or
a siphoning through the water cooling circuit into the .
exhaust, filling it up into the engine.
OVER-FILLING
CAUTION: The oil sump on this generator's engine can
unintentionally be over-filled!
After shutdown, the oil in the engines internal passages can
linger and take a number of hours to drain back into the oil
sump. Allow at least a few hours for the oil to settle back into
the sump before checking the dipstick. An overnight period
will provide an even more accurate dipstick reading.
(Re-starting the engine is not a problem as the engine's
internal passages are well lubricated).
Over-filling the engine's sump will result in erratic operation,
and/or a smokey white oil laden exhaust, hard starting and
possible no start.

COOLING SYSTEM
FRESH WATER COOLING CIRCUIT
Fresh water (antifreeze) is moved through the engine by a
belt driven circulating pump, absorbing heat from the engine.
Some of the coolant by-passes the thermostat to maintain
circulation in the engine and is drawn through the heat
exchanger. The engine operating temperature rises and the
thermostat reacts to this and starts to open allowing more
coolant to flow through the heat exchanger. The thermostat
opening will change as it gains control of the engine
operating tymperature by allowing more or less coolant
flow through it.
NOTE: Periodically check the conditiQn of the pressure cap.
Ensure that rhe upper and lower rubber seals are in good
condition and check that the vacuum valve opens and closes
tightly. Carry a spare cap.
ENGINE COOLANT
CHANGING COOLANT
WESTERBEKE recommends a mixture of 50% antifreeze
and 50% distilled water. Distilled water is free from the
chemicals that can corrode internal engine surfaces.
The antifreeze performs a double duty. It allows the engine to
run at proper temperatures by transferring heat away from
the engine to the coolant and lubricates and protects the cook
ing circuit from rust and corrosiol1. Look for a good quality
. antifreeze that contains Supplemental Cooling Additives
(SCAs) that keep the antifreeze chemically balanced, crucial
to long term protection.
The engine's coolant must be changed according to the
MAINTENANCE SCHEDULE. If the coolant is allowed to
become contaminated, it can lead to overheating problems.
NOTE: Look for the new environmentally friendly long lasting
antifreeze that is now available.
A CAUTION: PrDper cooling system maintenance is
critical; a substantial number of engine failures can be
traced back to cooling system corrosion.
Drain the engine coolant by loosening the drain plug on the
heat exchanger and opel1ing pressure cap. Also loosen the air
bleed petcock on the top of the heat exchanger
A CAUTION: The engine must be allowed to cool
The recommended 50/50 mixture will protect the engine
against the most extreme temperature. The antifreeze miXture
will also retard rust within the engine and add to the life of
the circulating pump impeller and seals.
A proper 50/50 mixture as recommended will protect the
engine coolant to temperatures of - 4O"F.
down before attempting these procedures. Not only is
the surface of the engine hot but coolant temperatures
can be at 190 0 F.
Refilling the Coolant
The coolant recovery tank allows for the expansion and contraction of the engines coolant during engine operation without introducing air into the system. This recovery tank is
provided anomust be installed oefore operating the engine.
NOTE: 171is tank, with its sltort run oJ plastIC hose, is best
located at or above the level of the engine:r manifold.
After closing the engine block drain, pour clean, premixed
coolant into the manifold and when the coolant is visible in
the manifold, start the engine and run it at slow idle. Open
the air bleed petcocks on the manifold and the thermostat
housing.
Monitor the coolant in the manifold and add as needed. Fill
the manifold to the filler neck and when the coolant flowing
from the petcock is free of air bubbles, clo.se the petcock and
install the pressure cap.
Remove the cap on the coolant recovery tank and fill with
coolant mix to halfway between LOW and MAX and replace
the cap. Run the engine and observe the coolant expansion
flow into the recovery tank. When the petcock on the thermostat housing is free of air bubbles, close that petcock.
After checking for leaks, stop the' generator and allow it to
cool. Coolant should draw back into the cooling system as
the engine cools down. Add coolant to the recovery tank if
needed. Clean up any spilled coolant.

THERMOSTAT
A thennostat, located in the coolant filler cap housing (illustrated below), controls the coolant's temperature by
allowing more or less coolant through it to the engine's heat
exchanger. When the engine is first started, the closed
thennostat prevents coolant from flowing through it to the
heat exchanger. Some coolant is by-passed via a by-pass
hose on the sump plate to the exchanger. This provides for
coolant circulation in the engine and for coolant temperature
rise. As the coolant wanns up, the thennostat gains control
of the engine operating temperature by allowing more or less
coolant flow to the exchanger. The thennostat is accessible
and can be replaced easily. Carry a spare thennostat and
housing gasket.

ZINC ANO'DE
A zinc anode, or pencil, is located in the raw water cooling
circuit within the heat exchanger. The purpose of the zinc
anode is to sacrifice itself to electrolysis action taking place
in the raw water cooling circuit, thereby reducing the effects
of electrolysis on other components of the system. The
condition of the zinc anode should be checlq!d monthly and
the anode cleaned or replaced as required. Spare anodes
should be carried on board.

CLEAN & REUSE
If the zinc pencil needs replacement, hold the hex boss into
which the zinc pencil is threaded with a wrench while
loosening the anode with another wrench. This prevents the
hex boss from possibly tearing off the exchanger shell. After
removing the zinc, note the condition of it. If the zinc is in
poor condition, there are probably zinc flakes within the
exchanger. Remove the end of the heat exchanger and clean
the inside of all zinc debris. Always have a spare heat
exchanger end gasket in case the present one becomes
damaged when removing the end cover. Replace the gasket
(refer to your engine model's heat exchanger end gasket part
number), o-ring, cover, and install a new zinc anode.
HEAT EXCHANGER
Cool raw water flows through the inner tubes of the heat
exchanger. As the engine coolant passes around these tubes,
the heat of the internal engine is conducted to the raw water
which is then pumped into the exhaust system and
discharged. The engine coolant (now cooled) flows back
through the engine and the circuit repeats itself.
The engine coolant and raw water are independent of each
other; this keeps the engine's water passages clean from the
harmful deposits found in raw water.
NOTE: The threads of the zinc anodes are pipe threads and do
not require sealant. Sealant should not be used as it may
insulate the zinc from the metal of the heat exchanger
housing preventing electrolysis action on the zinc.
Heat Exchanger Service
After approximately 1000 hours of operation, remove, clean
and pressure test the engine's heat exchanger. (A local
automotive radiator shop should be able to clean and test the
heat exchanger.)
NOTE: Operating in silty and/or tropical waters may require
that a heat exchanger cleaning be performedmore often than
every 1000 hours.

COOLING SYSTEM I WATER PUMPS
DESCRIPTION
CHANGING THE WATER PUMP IMPELLERS
The fresh water cooling system has the raw water pump
mounted above the fresh water (coolant) pump as illustrated.
These pumps are self-priming, rotary pumps, with
non-ferrous housings and Neoprene impellers. The impellers
have flexible blades that wipe against a curved cam plate
within the impeller housing, producing the pumping action.
These pumps can not be allowed to run dry. There should
always be a spare impeller and impeller cover gasket aboard
(an impeller kit). Water pump impeller failures occur when
lubricant (water) is not present during engine operation. Such
failures are not warrantable, and operators are cautioned to
make sure water flow is present at start-up. Water pumps
should be inspected periixlically for broken or tom impeller
blades. See MAINTENANCE SCHEDULE.
Remove the cover screws and the cover will separate the
upper pump (raw water) from the fresh water (coolant) pump
as shown in the illustration. Close the raw water thru hull
seacock. This will prevent water syphoning out of the pump
while the impeller is being changed.
1. Remove the wear plate to expose the impeller. Notice the
direction the impeller blades are working in so as to
install the replacement impeller with blades working in
the same direction.
.2. Using pliers, grab the impeller hub and withdraw the
impeller from the pump. Inspect the inside of the pump,
the cam, the inner wear plate, and the inside surface of the
cover plate for wear. Replace any worn components.
3. Wipe the inside surface of the pump dry. Apply a film of
glycerin supplied in the impeller kit to the inside pump
surfaces and to the exposed area of the shaft lip seal.
4. Install the new impellers with a rotating motion so the
blades are working in the same direction as those of the
removed impeller.
NOTE: Should a failure occur with the pumps internal parts
(seals and bearings) it may be more cost efficient to purchase
a new pump and rebuild the original pump as a spare.
PUMP COVER
5. Apply glycerin to the O-ring, impeller, gasket, the wear
plate and assemble into the pump housing. Reassemble
the upper pump (raw water) making certain the fasteners
are tight. Re-install any hoses that were removed.

raw water should discharge from the exhaust and there
should not be any leaks around the pumps.
A
WARNING: When the engine is started, make
sure that the pumps are pumping within 30 seconds
after engine start. If not, "stop" the engine at once
and couect the problem.
To increase the service life of the impeller, do not install
them in the pump if the engine will be in storage for
. longer than 3 months. Store the impellers in a dark, cool, and
dry location. Replace the cover plate on the pumps securely
and ensure the thru hull seacock is closed.

DC CIRCUIT/BATTERY
DESCRIPTION
Testing the Circuit
The DC Circuit functions to start, operate and stop the
generator's engine. The circuit is best understood by
reviewing the DC Wiring Diagram and Wiring Schematic.
The engine's DC wiring is designed with three simple basic
circuits: start, run, and stop.
If the battery is not charging, check the fuse. To test the
circuit, remove the fuse and test with a voltmeter between the
fuse holder connection and ground. With the engine running,
it should indicate 13-14 volts. If only battery voltage is
indicated, check the terminal connections at the battery.
The engine has a 12 volt DC electrical control circuit that is
shown on the Wiring Diagrams. Refer to these diagrams
when troubleshooting or when servicing the DC electrical
system on the engine.
Battery Maintenance
Review the manufacturer's recommendations and then
establish a systematic maintenance schedule for your
engine's starting batteries and house batteries.
A CAUTION: To avoid damage to the battery charging
• Check the electrolyte level and specific gravity with a
hydrometer.
circuit, never shut off the engine battery switch while
the engine is running. Shut off the engine battery switch,
however, to avoid electrical shorts when working on the
engine's electrical circuit.
• Use only distilled water to bring electrolytes to a proper
level.
• Make certain that battery cable connections are clean and
tight to the battery posts (and to your engine).
Specifications
The minimum recommended capacity of the dedicated battery
used in the engine's 12 volt DC control circuit is 600-900 CCA.
• Keep your batteries clean and free of corrosion.
Battery Charging Circuit
The engine supplies a continuous 6 amp charge from the
voltage regulator to the engine's battery. This charge passes
thru an 8 amp fuse (and the ships battery switch).
SHORE POWER TRANSFER SWITCH
If the installer connects shore power to the vessel's AC
circuit, this must be done by means of the Shore Power
Transfer Switch. Set the transfer switch shown in the
diagrams to the OFF position. This switch prevents
simultaneous connection of shore power to generator output.
Generator
A
utility shore power and generator output are connected
at the same time. This type of generator damage is not .
covered under the warranty; it is the installer's
responsibility to make sure all AC connections are
correct.

OIL PRESSURE
TESTING OIL PRESSURE
The lubricating system is a pressure feeding system using an
oil pump. The engine oil is drawn from the oil sump by the
oil pump, which drives the oil, under pressure, through the
oil filter and various lubricating parts in the engine. The oil
then returns to the oil sump to repeat the continuous cycle.
When the oil pressure exceeds the specified pressUre, the oil
pushes open the relief valve in the oil pump and returns to
the oil sump, keeping the oil pressure within it's specified
range.
To test the, oil pressure, remove the oil switch and install a
mechanical oil pressure gauge, in it's place, it win b,e
necessary to cOl.1nect the two switch wires together for the
engine to run. After warming up the engine, with the engine
speed at 2200 rpm, read the oil pressure gauge.
OIL PRESSURE: between 30 and 40 psi at 2200 rpm
MECHANICAL OIL
PRESSURE GAUGE
NOTE: A newly starter (cold) engine may have an oil

1. Remove both spark plug caps and both spark plugs.
2. Install a compression adapter and gauge in a spark
plug hole.
3. Close the thru hull valve (seacock).
4. Crank the engine several times quickly so that the gauge
pointer reaches it's maximum.
To remove, replace or adjust the belt, loosen the pivot bolt
and release the adjusting bolt. Slide the water pump bracket
to slacken the belt for removal. When replacing and
adjusting the belt, set the belt very tight and tighten the bolt
and nut.
STANDARD COMPRESSION PRESSURE AT 5DD RPM:
71 PSI (5± 1 Kg/cm') (D.4± D.1 MPa)
5. Test the compression pressure on the other cylinder.
If either cylinder is below the standard try adding a
small amount of engine oil through the spark plug hole
and repeat the test.
(a) If additional oil causes an increase of pressure,
the piston ring and/or cylinder may be worn
or damaged.
(b) If additional oil does not increase compression
pressure suspect poor valve contact, valve seizure
or valve wear.

GENERATOR INFORMATION
USE OF ELECTRIC MOTORS
Required Operating Speed
The power required to start an electric motor is considerably.
more than is required to keep it running after it is started.
Some motors require much more current to start them than
others. Split-phase (AC) motors require more current to start,
under similar circumstances, than other types. They are commonly used on easy-starting loads, such as washing
machines, or where loads are applied after the motor is
started, such as small powertools. Because they require 5 to
7 times as much current to start as to run, their use should be
avoided, whenever possible, if the electric motor is to be
driven by a small generator. Capacitor and repulsioninduction motors require from 2 to 4 times as much current
to start as to run. The current required to start any motor
varies with the load connected to it. An electric motor connected to an air compressor, for example, will require more
current than a motor to which no load is connected.
Run the generator first with no load applied, then at half the
generator's capacity, and finally loaded to its full capacity as
indicted on the generators data plate. The output voltage
should be checked periodically to ensure proper operation of
the generating plant and the appliances it supplies. To
monitor voltage and load, check it with a portable meter and
amp probe.
Generator Maintenance
Maintaining reasonable cleanliness is important. Connections
of terminal boards and rectifiers may become corroded, and
insulation surfaces may start conducting if salts, dust, engine
exhaust, carbon, etc. are allowed to build up. Clogged
ventilation openings may cause excessive heating and
reduced life of windings.
In addition to periodic cleaning, the generator should be
inspected for tightness of all connections, evidence of
overheated terminals andloose or damaged wires.
In general, the current required to start U5-Volt motors connected
to medium starting loads will be approximately as follows:

-~
*NOTE: In the above table the maximum Amps for Starting is
more for some small motors than for larger ones. TIw reason
for this is that the hardest starting types (split-phase) are not
made in larger sizes.
Because the heavy surge of current needed for starting
motors is required for only an instant, the generator will not
be damaged if it can bring the motor up to speed in a few
seconds. If difficulty is experienced in starting motors, turn
off all other electrical loads and, if possible, reduce the load
on the electric motor.

LAY-UP & RECOMMISSIONING
GENERAL
INTAKE MANIFOLD
Many owners rely on their boatyards to prepare their craft,
including engines and generators, for lay-up during the
off-season or for long periods of inactivity. Others prefer
to accomplish lay-up preparation themselves.
The procedures which follow will allow you to perform your
own lay-up and recommissioning, or you may use them as a
check list if others do the procedures.
These procedures should afford your engine protection
during a lay-up and also help familiarize you with the
maintenance needs of your engine.
If you have any questions regarding lay-up procedures, call
your local servicing dealer; he will be more than willing to
provide assistance.
Clean the filter screen in the flame arrester, and place a clean
cloth lightly soaked in lube oil around the flame arrester to
block any opening. Also place an oil-soaked cloth in the
through-hull exhaust port, Make a note to remove cloths
prior to start-up!
CYLINDER/SPARK PLUGS
Spray fogging oil into the open air intake, with the flame
arrester removed, while the engine is running. The fogging
oil will stall the engine and coat the intake components,
valves, cylinders and spark plugs for winter protection.
NOTE: At re-commissioning, remove the spark plugs and
clean and gap them. Rotate the engine by hand two complete
revolutions. Re-install the spark plugs and tighten securely
and firmly attach the high tension leds.
LUBRICATION SYSTEM
With the engine warm, drain all the lubricating oil from the
oil sump. Remove and replace the oil filter and fill the sump
with new oil. Use the correct grade of oil. Refer to the
ENGINE LUBRICATING OIL pages in this manual for the
oil changing procedure. Run the engine make sure there are
no leaks.
A CAUTION: 00 not leave the engine's old engine
oil in the sump over the lay-up period. Lubricating oil
and combustion deposits combine to produce harmful
chemicals which can reduce the life of your engine's
internal parts.
Recommissioning
FUEL SYSTEM
Top off your fuel tanks with unleaded gasoline of 89 octane
or higher. A fuel conditioner such as stabil gasoline stabilizer
should be added. Change the element in your gasoline/water
separator and clean the metal bowl. Re-install and make
certain there are no leaks. Clean up any spilled oil.
STARTER MOTOR
Lubrication and cleaning of the starter drive pinion is
advisable, the pinion is accessible when the flywheel cover is
removed. Make sure the battery connections are shut off
before attempting to remove the starter. Take care in properly
replacing any electrical connections removed from the starter.
SPARE PARTS
Lay-up time provides a good opportunity to inspect your
Westerbeke engine to see if external items such as drive belts
or coolant hoses need replacement. Check your basic spares
kit and order items not on hand, or replace those items used
during the lay-up, such as filters and zinc anodes. Refer to
the SPARE PARTS section of this manual.
BATTERIES
If batteries are to be left on board during the lay-up period,
make sure that they are fully charged, and will remain that
way, to prevent them from freezing. If there is any doubt that
the batteries will not remain fully charged, or that they will
be subjected to severe environmental conditions, remove the
batteries and store them in a warmer, more compatible
environment.
4. Check the conditlon of the heat exchanger zinc, clean or
replace as needed.
5. Make certain all electrical connections and switches are
in the correct position and there are no-loads on the
generator at start-up (see GENERATOR).
6. Inspect the fresh water pump impeller, replace if
necessary.
7. Start the engine in accordance with the procedures
described in the PREPARATIONS FOR STARTING
section of this manual.
The recommissioning of your Westerbeke engine after a
seasonal lay-up generally follows the same procedures as
those described in the PREPARATIONS FOR STARTING
section regarding preparation for starting and normal starts.
However, some of the lay-up procedures will need to be
counteracted before starting the engine.
1. Remove any rags that were placed in the exhaust, intake
manifold, or flame arrester.
2. Reinstall the batteries that were removed during the
lay-up, and reconnect the battery cables, making sure the
terminals are clean and that the connections are tight.
Check to make sure that the batteries are fully charged,
remove the sparl plugs, wipe clean, re-gap, and install to
proper tightness.
3. Make certian the cooling system intake hose is attached
and the thru-hull valve is open. .
