Safety information
EMU33622
Outboard motor safety
Observe these precautions at all times.
EMU36501
Propeller
People can be injured or killed if they come in
contact with the propeller. The propeller can
keep moving even when the motor is in neutral, and sharp edges of the propeller can cut
even when stationary.
● Stop the engine when a person is in the water near you.
● Keep people out of reach of the propeller,
even when the engine is off.
EMU40271
Rotating parts
Hands, feet, hair, jewelry, clothing, personal
flotation device (PFD) straps, etc., can become entangled with internal rotating parts of
the engine, resulting in serious injury or death.
Keep the top cowling in place whenever possible. Do not remove or replace the top cowling with the engine running.
Only operate the engine with the top cowling
removed according to the specific instructions
in the manual. Keep hands, feet, hair, jewelry,
clothing, PFD straps, etc., away from any exposed moving parts.
EMU33640
Hot parts
During and after operation, engine parts are
hot enough to cause burns. Avoid touching
any parts under the top cowling until the engine has cooled.
EMU33650
Electric shock
Do not touch any electrical parts while starting
or operating the engine. They can cause
shock or electrocution.
EMU40861
Power trim and tilt
Body parts can be crushed between the outboard motor and the clamp bracket when the
outboard motor is trimmed or tilted. Keep
body parts out of this area at all times. Make
sure that no one is in this area before operating the power trim and tilt mechanism.
The power trim and tilt switches operate even
when the main switch is turned to the “
”
(off) position. Keep people away from the
power trim and tilt switches whenever working
around the outboard motor.
Never get under the outboard motor while it is
tilted, even when the tilt support shaft is installed. Severe injury could occur if the outboard motor accidentally falls.
EMU41251
Engine shut-off cord (lanyard)
Attach the engine shut-off cord so that the engine stops if the operator falls overboard or
leaves the helm. This prevents the boat from
running away under power and leaving people stranded, or running over people or objects.
Always attach the engine shut-off cord to a
secure place on your clothing or your arm or
leg while operating. Do not remove it to leave
the helm while the boat is moving. Do not attach the engine shut-off cord to clothing that
could tear loose, or route the engine shut-off
cord where it could become entangled, preventing it from functioning.
Do not route the engine shut-off cord where it
is likely to be accidentally pulled out. If the engine shut-off cord is pulled during operation,
the engine will shut off and you will lose most
steering control. The boat could slow rapidly,
throwing people and objects forward.
EMU33810
Gasoline
Gasoline and its vapors are highly flammable and explosive. Always, refuel according to the procedure on page 54 to reduce the
risk of fire and explosion.
1
U6CB10E0.book Page 2 Wednesday, September 30, 2009 9:49 AM
Safety information
EMU33820
Gasoline exposure and spills
Take care not to spill gasoline. If gasoline
spills, wipe it up immediately with dry rags.
Dispose of rags properly.
If any gasoline spills onto your skin, immediately wash with soap and water. Change
clothing if gasoline spills on it.
If you swallow gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get
immediate medical attention. Never siphon
fuel by mouth.
EMU33900
Carbon monoxide
This product emits exhaust gases which contain carbon monoxide, a colorless, odorless
gas which may cause brain damage or death
when inhaled. Symptoms include nausea,
dizziness, and drowsiness. Keep cockpit and
cabin areas well ventilated. Avoid blocking exhaust outlets.
EMU33780
Modifications
Do not attempt to modify this outboard motor.
Modifications to your outboard motor may reduce safety and reliability, and render the outboard unsafe or illegal to use.
EMU33740
Boating safety
This section includes a few of the many important safety precautions that you should follow when boating.
EMU33710
Alcohol and drugs
Never operate after drinking alcohol or taking
drugs. Intoxication is one of the most common
factors contributing to boating fatalities.
EMU40280
Personal flotation devices (PFDs)
Have an approved PFD on board for every occupant. Yamaha recommends that you must
wear a PFD whenever boating. At a minimum,
children and non-swimmers should always
2
wear PFDs, and everyone should wear PFDs
when there are potentially hazardous boating
conditions.
EMU33731
People in the water
Always watch carefully for people in the water, such as swimmers, skiers, or divers,
whenever the engine is running. When someone is in the water near the boat, shift into
neutral and stop the engine.
Stay away from swimming areas. Swimmers
can be hard to see.
The propeller can keep moving even when
the motor is in neutral. Stop the engine when
a person is in the water near you.
EMU33751
Passengers
Consult your boat manufacturer’s instructions
for details about appropriate passenger locations in your boat and be sure all passengers
are positioned properly before accelerating
and when operating above an idle speed.
Standing or sitting in non-designated locations may result in being thrown either overboard or within the boat due to waves, wakes,
or sudden changes in speed or direction.
Even when people are positioned properly,
alert your passengers if you must make any
unusual maneuver. Always avoid jumping
waves or wakes.
EMU33760
Overloading
Do not overload the boat. Consult the boat capacity plate or boat manufacturer for maximum weight and number of passengers. Be
sure that weight is properly distributed according to the boat manufacturers instructions. Overloading or incorrect weight
distribution can compromise the boats handling and lead to an accident, capsizing or
swamping.
U6CB10E0.book Page 3 Wednesday, September 30, 2009 9:49 AM
Safety information
EMU33772
EMU33800
Avoid collisions
Accident reporting
Scan constantly for people, objects, and other
boats. Be alert for conditions that limit your
visibility or block your vision of others.
Boat operators are required by law to file a
Boating Accident Report with their state boating law enforcement agency if their boat is involved in any of the following accidents:
1. There is loss of life or probable loss of life.
2. There is personal injury that requires
medical attention beyond first aid.
3. There is property damage to boats or other property over a certain amount.
4. There is complete loss of a boat.
Contact local law enforcement personnel if a
report is necessary.
ZMU06025
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other boats.
● Do not follow directly behind other boats or
waterskiers.
● Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or understand where you are going.
● Avoid areas with submerged objects or
shallow water.
● Ride within your limits and avoid aggressive
maneuvers to reduce the risk of loss of control, ejection, and collision.
● Take early action to avoid collisions. Remember, boats do not have brakes, and
stopping the engine or reducing throttle can
reduce the ability to steer. If you are not
sure that you can stop in time before hitting
an obstacle, apply throttle and turn in another direction.
EMU33790
Weather
Stay informed about the weather. Check
weather forecasts before boating. Avoid boating in hazardous weather.
EMU33870
Boat education and training
Operators should take a boating safety
course. This may be required in your state.
Many of the organizations listed in the next
section can provide information about courses in your area.
You may also want to consider an Internetbased program for basic boater education.
The Online Boating Safety Course provided
by the BoatU.S. Foundation, is approved by
the National Association of State Boating Law
Administrators (NASBLA) and recognized by
the United States Coast Guard. Most, but not
all, states accept this course to meet their
minimum requirements. While it cannot replace an in-depth course such as one offered
by the U.S. Coast Guard, U.S. Power Squadron, or other organization, this online course
does provide a general overview of the basics
in boating safety, requirements, navigation,
and operation. Upon successful completion of
the course, the user can download a certificate of completion immediately or, for a small
charge, request one by mail. To take this free
course, go to boatus.org.

EMU33691
Basic boating rules (Rules of
the road)
Just as there are rules that apply when you
are driving on streets and highways, there are
waterway rules that apply when you are driving your boat. These rules are used internationally. (For U.S.A.: and are also enforced by
the United States Coast Guard and local
agencies.) You should be aware of these
rules, and follow them whenever you encounter another vessel on the water.
EMU33700
Steering and sailing rules and sound
signals
Whenever two vessels on the water meet one
another, one vessel has the right-of-way; it is
called the “stand-on” vessel. The vessel that
does not have the right-of-way is called the
U6CB10E0.book Page 5 Wednesday, September 30, 2009 9:49 AM
Safety information
“give-way” or “burdened”vessel. These rules
determine which vessel has the right-of-way,
and what each vessel should do.
Stand-on vessel
The vessel with the right-of-way has the duty
to continue its course and speed, except to
avoid an immediate collision. When you maintain your direction and speed, the other vessel
will be able to determine how best to avoid
you.
Give-way vessel
The vessel that does not have the right-ofway has the duty to take positive and timely
action to stay out of the way of the Stand-On
vessel. Normally, you should not cross in front
of the vessel with the right-of-way. You should
slow down or change directions briefly and
pass behind the other vessel. You should always move in such a way that the operator of
the other vessel can see what you are doing.
“ The general prudential rule ”
This rule is called Rule 2 in the International
Rules and says,
“ In obeying and construing these rules due
regard shall be had to all dangers of navigation and collision, and to any special circumstances, which may render a departure from
the above rules necessary in order to avoid
immediate danger.”
In other words, follow the standard rules except when a collision will occur unless both
vessels try to avoid each other. If that is the
case, both vessels become “ Give-Way ” vessels.
Meeting: (you are approaching another vessel head-on)
Crossing: (you are traveling across the other
vessel’s path)
Overtaking: (you are passing or being
passed by another vessel)
In the following illustration, your boat is in the
center. You should give the right-of-way to
any vessels shown in white area (you are the
Give-Way vessel). Any vessels in the shaded
area must yield to you (they are the Give-Way
vessels). Both you and the meeting vessel
must alter course to avoid each other.
Meeting
If you are meeting another power vessel head
on, and are close enough to run the risk of collision, neither of you has the right-of-way Both
of you should alter course to avoid an accident. You should keep the other vessel on
your port (left) side. This rule doesn’t apply if
both of you will clear one another if you continue on your set course and speed.
EMU25521
Rules when encountering vessels
There are three main situations that you may
encounter with other vessels which could lead
to a collision unless the Steering Rules are followed:
5
U6CB10E0.book Page 6 Wednesday, September 30, 2009 9:49 AM
Safety information
EMU25531
Other special situations
Crossing
When two power driven vessels are crossing
each other’s path close enough to run the risk
of collision, the vessel which has the other on
the starboard (right) side must keep out of the
way of the other. If the other vessel is on your
right, you must keep out of its way; you are the
Give-Way vessel. If the other vessel is on
your port (left) side, remember that you
should maintain course and direction, provided the other vessel gives you the right-of-way
as it should.
Overtaking
If you are passing another vessel, you are the
“Give-Way” vessel. This means that the other
vessel is expected to maintain its course and
speed. You must stay out of its way until you
are clear of it. Likewise, if another vessel is
passing you, you should maintain your speed
and direction so that the other vessel can
steer itself around you.
6
There are three other rules you should be
aware of when driving your boat around other
vessels.
Narrow channels and bends
When navigating in narrow channels, you
should keep to the right when it is safe and
practical to do so. If the operator of a powerdriven vessel is preparing to go around a
bend that may obstruct the view of other water
vessels, the operator should sound a prolonged blast on the whistle (4 to 6 seconds). If
another vessel is around the bend, it too
should sound the whistle. Even if no reply is
heard, however, the vessel should still proceed around the bend with caution. If you navigate such waters with your boat, you will
need to carry a portable air horn, available
from local marine supply stores.
Fishing vessel right-of-way
All vessels that are fishing with nets, lines or
trawls are considered to be “fishing vessels”
under the International Rules. Vessels with
trolling lines are not considered fishing vessels. Fishing vessels have the right-of-way regardless of position. Fishing vessels cannot,
however, impede the passage of other vessels in narrow channels.
Sailing vessel right-of-way
Sailing vessels should normally be given the
right-of-way. The exceptions to this are:
1. When the sailing vessel is overtaking the
power-driven vessel, the power-driven
vessel has the right-of-way.
2. Sailing vessels should keep clear of any
fishing vessel.
3. In a narrow channel, a sailing vessel
should not hamper the safe passage of a
power-driven vessel that can navigate
only in such a channel.
U6CB10E0.book Page 7 Wednesday, September 30, 2009 9:49 AM
Safety information
Reading buoys and other markers
The waters of the United States are marked
for safe navigation by the lateral system of
buoyage. Simply put, buoys and markers
have an arrangement of shapes, colors, numbers and lights to show which side of the buoy
a boater should pass on when navigating in a
particular direction. The markings on these
buoys are oriented from the perspective of being entered from seaward (the boater is going
towards the port). This means that red buoys
are passed on the starboard (right) side when
proceeding from open water into port, and
black buoys are to port (left) side. When navigating out of port, your position with respect to
the buoys should be reversed; red buoys
should be to port and black buoys to starboard.
Many bodies of water used by boaters are entirely within the boundaries of a particular
state. The Uniform State Waterway Marking
System has been devised for these waters.
This system uses buoys and signs with distinctive shapes and colors to show regulatory
or advisory information. These markers are
white with black letters and orange boarders.
They signify speed zones, restricted areas,
danger areas, and general information.
Remember, markings may vary by geographic location. Always consult local boating authorities before driving your boat in unfamiliar
waters.

Propeller selection
Next to selecting an outboard motor, selecting
the right propeller is one of the most important
purchasing decisions a boater can make. The
type, size, and design of your propeller have
a direct impact on acceleration, top speed,
fuel economy, and even engine life. Yamaha
designs and manufactures propellers for every Yamaha outboard motor and every application.
Your Yamaha dealer can help you select the
right propeller for your boating needs. Select
a propeller that will allow the engine to reach
the middle or upper half of the operating
range at full throttle with the maximum boatload. Generally, select a larger pitch propeller
for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that vary widely, select the propeller that
lets the engine run in the proper range for your
maximum load but remember that you may
need to reduce your throttle setting to stay
within the recommended engine speed range
when carrying lighter loads.

Fuel requirements
EMU41330
Gasoline
Use a good quality gasoline that meets the
minimum octane requirement. If knocking or
pinging occurs, use a different brand of gasoline or premium unleaded fuel. Yamaha recommends that you use alcohol-free gasoline
(see Gasoline with Ethanol) whenever possible.
The use of a poor quality gasoline may result
in starting and running problems. If you encounter drivability problems, which you suspect could be related to the fuel you are using,
we recommend that you switch to a recognized high quality brand of gasoline, such as
a gasoline that is advertised as Top Tier Detergent Gasoline. Failure to comply with these
recommendations may also result in unscheduled maintenance, fuel system damage, and internal engine damage.
Recommended fuel:
VF200A Regular unleaded gasoline

NOTICE
●
●
Do not use leaded gasoline. Leaded gasoline can seriously damage the engine.
Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance or engine damage. Use only fresh gasoline that has
been stored in clean containers.
Gasoline with Ethanol
Two types of gasoline are commonly available in the U.S.A. for use in automobiles and
boats: conventional gasoline without Ethanol
and gasoline with Ethanol, which is typically
referred to as E10 gasoline. According to federal regulations, E10 gasoline may contain up
to 10% Ethanol.
A high quality gasoline without Ethanol is the
preferred fuel for your Yamaha outboard motor. However, if gasoline with Ethanol is the
only fuel available in your area, your Yamaha
outboard motor is calibrated to run properly
on fresh E10 gasoline that meets the minimum octane requirement specified for this
model.
ECM02400
NOTICE
Never use a gasoline for your outboard
motor that contains more than 10% Ethanol, such as E85 which contains 85% Ethanol, or gasoline containing any amount
of Methanol. These fuels can cause start-
16
U6CB10E0.book Page 17 Wednesday, September 30, 2009 9:49 AM
Specifications and requirements
ing and running problems, as well as serious fuel system and internal engine
damage.
Gasoline containing ethanol has several
properties that may cause boat fuel system
problems.
● Ethanol is a strong solvent (cleaning agent)
that can clean gum and varnish deposits
from a boat’s fuel system, particularly in older boats, as well as tanks and pipes used in
gasoline distribution. These released deposits contaminate the fuel and can cause
problems, such as clogged fuel filters, carburetors, or fuel injectors, which could result in engine damage.
● Ethanol may dissolve resins used in the
construction of fiberglass fuel tanks. The
dissolved resins contaminate the fuel and
can cause problems, such as clogged fuel
filters, carburetors, or fuel injectors, which
could result in engine damage.
● Ethanol is hygroscopic (has a strong attraction to water). Therefore, any water that inadvertently enters the fuel system,
including moisture that is absorbed from the
air, will mix with the ethanol in the gasoline.
If the amount of water is excessive, the ethanol and water mixture will separate from
the gasoline in a layer at the bottom of the
fuel tank. This ethanol and water mixture is
very corrosive to aluminum fuel tanks and
fuel system components.
● The usable life span of E10 gasoline may
be shorter than the normal length of off-season boat storage, causing starting and running problems related to stale fuel.
For more information on using fuel containing
ethanol, visit: http://www.yamaha-motor.com
Gasoline Filtration
Yamaha outboard motors are equipped with
internal fuel filters. However, excessive water
or debris entering your engine’s fuel system
could prematurely clog the internal filters,
causing starting and running problems, fuel
system damage, and internal engine damage.
Therefore, it is recommended that an external
10-micron water-separating fuel filter be installed on your boat and serviced frequently.
Consult your authorized Yamaha dealer for a
10-micron filter that meets your engine’s requirements.
EMU41340
Gasoline Additives
Gasoline blends change to meet automobile
emission regulations and economic conditions. Additives, added by gasoline distributors, necessary for proper automobile engine
operation and durability, may not be sufficient
for typical boat applications. Intake valve and
combustion chamber deposits may accumulate in boat engines more rapidly than encountered in automotive use. In addition,
gasoline used for boating will typically age
longer between refills than gasoline used in
automobiles, resulting in stale and unusable
gasoline that may cause starting and running
problems, fuel system damage, and internal
engine damage.
Yamaha recommends the use of two Yamalube gasoline additives to reduce internal
deposits and extend the storage life of gasoline. Continuous use of Yamalube Ring Free
Fuel Additive Plus reduces harmful internal
deposits. Yamalube Fuel Stabilizer & Conditioner Plus added to fresh gasoline will help
protect the fuel system from varnishing while
helping to keep the gasoline’s octane level
from decreasing excessively during storage.
Other additives may also be available on the
market that may have varying degrees of ef-

fectiveness. Consult your Yamaha dealer
concerning what may work best for the locally
available gasoline and environmental conditions.
EMU41350
Anti-fouling paint
A clean hull is required to maintain your boat’s
performance. Boats moored in the water
should be protected from marine growth (barnacles, mussels, and marine plants). If approved by regulations for your area, the
bottom of the hull can be coated with an antifouling paint to inhibit marine growth.
Anti-fouling paints specifically formulated for
use on aluminum may be applied to the outboard motor. The original Yamaha paint surface may be scuffed lightly before applying
anti-fouling paint, but do not remove the original paint. Removal of the original paint will increase the rate of corrosion.
ECM02410
NOTICE
Anti-fouling paint for fiberglass and wood
may contain materials, such as copper,
graphite, and tin, that can cause corrosion
if applied to aluminum boats and outboard
motor components. Never apply these
types of paint to your outboard motor because rapid corrosion damage could occur.
EMU40301
Outboard motor disposal requirements
Never illegally discard (dump) the outboard
motor. Yamaha recommends consulting the
dealer about discarding the outboard motor.
EMU36352
Emergency equipment
Keep the following items onboard in case
there is trouble with the outboard motor.
● A tool kit with assorted screwdrivers, pliers,
wrenches (including metric sizes), and
electrical tape.
● Waterproof flashlight with extra batteries.
● An extra engine shut-off cord (lanyard) with
clip.
● Spare parts, such as an extra set of spark
plugs.

operator fall overboard or leave the helm, the
cord will pull out the clip, stopping ignition to
the engine. This will prevent the boat from
running away under power. WARNING! Attach the engine shut-off cord to a secure
place on your clothing, or your arm or leg
while operating. Do not attach the cord to
clothing that could tear loose. Do not route
the cord where it could become entangled,
preventing it from functioning. Avoid accidentally pulling the cord during normal
operation. Loss of engine power means
the loss of most steering control. Also,

speed (r/min) between the port and starboard
engines for reference purposes when synchronizing the two engines’ speeds.
ZMU01752
If twin engines are installed on your boat, the
gauge will only display the total fuel economy
of both engines.
● Fuel consumption varies greatly with boat
design, weight, propeller used, engine trim
angle, sea conditions (including wind), and
throttle position. Fuel consumption also varies slightly with the type of water (salt, fresh,
and contaminate levels), air temperature
and humidity, cleanliness of the boat bottom, engine mounting height, skill of the operator, and individual gasoline formulation
(winter or summer fuel and amount of additives).
● The Yamaha digital speedometer and fuel
management meter calculates speed,
miles traveled, and fuel economy by water
movement at the stern of the boat. This distance can vary greatly from the actual distance traveled because of water currents,
sea swells, and the condition of the water
speed sensor (if partially plugged or damaged).
● Individual engines may slightly vary in their
fuel consumption due to manufacturing
variations. These variations can be even
greater if the engines are of different year
models. In addition, variations in propellers,
even of the same basic dimensions of the
same design, can also cause a slight variation in fuel consumption.

Installation
The information presented in this section is intended as reference only. It is not possible to
provide complete instructions for every possible boat and outboard motor combination.
Proper mounting depends in part on experience and the specific boat and outboard motor combination.
EWM02572
WARNING
●
●
Overpowering a boat could cause severe instability. Do not mount an outboard motor with more horsepower than
the maximum rating on the capacity
plate of the boat. If the boat does not
have a capacity plate, consult the boat
manufacturer.
Improper mounting of the outboard motor could result in hazardous conditions,
such as poor handling, loss of control,
or fire hazards. Have your Yamaha dealer mount the outboard motor properly.
Mounting height
The mounting height of your outboard motor
affects its efficiency and reliability. If it is
mounted too high, propeller ventilation may
occur, which will reduce propulsion due to excessive propeller slip, and the cooling water
inlet for the cooling system may not get adequate water supply, which can cause engine
overheating. If the engine is mounted too low,
water resistance (drag) will increase, thereby
reducing engine efficiency and performance.
The optimum mounting height depends on
the combination of the boat and outboard motor. Consult your Yamaha dealer or boat manufacturer for further information on
determining the proper mounting height.
ECM01634
NOTICE

●
EMU41270
Mounting the outboard motor
The outboard motor should be mounted so
that the boat is well balanced. Otherwise, the
boat could be hard to steer. Mount the outboard motor on the centerline (keel line) of the
boat.

ZMU01760
Make sure that the idle hole is high
enough to prevent water from entering
the engine even if the boat is stationary
with the maximum load.
Incorrect engine height or obstructions
to the smooth flow of water (such as the
design or condition of the boat, or accessories, such as transom ladders or
depth finder transducers) can create airborne water spray while the boat is
cruising. If the outboard motor is operated continuously in the presence of airborne water spray, enough water could
enter the engine through the air intake
opening in the top cowling to cause severe engine damage. Remove the cause
of the airborne water spray.

Filling engine oil
The outboard motor is shipped from the factory without engine oil. If your Yamaha dealer
did not fill the engine with engine oil, you must
fill the engine before starting it. NOTICE:
Make sure that the engine is filled with engine oil before operating the outboard motor for the first time. Otherwise, the engine
could be damaged severely. [ECM02240]
The following sticker, which is affixed to the
outboard motor when it is shipped from the
factory, should be removed after the engine is
filled with engine oil for the first time. For more
information on checking the engine oil level,
see page 50.
Operate the engine in the water under load (in
gear with a propeller installed) for 10 hours as
follows. When breaking in the engine, avoid
extended idling, rough water, and crowded areas.
1. For the 1st hour of operation:
Operate the engine at varying speeds up
to 2000 r/min or approximately 1/2 throttle.
2. For the 2nd hour of operation:
Increase the engine speed until the boat
is on plane (but avoid full-throttle operation), and then back off on the throttle
while keeping the boat at a planing
speed.
3. For the remaining 8 hours of operation:
Operate the engine at any speed. However, avoid operating at full throttle for
more than 5 minutes at a time.
4. After the 1st 10 hours of operation:
Operate the engine normally.

WARNING
Excessive trim for the operating conditions (either trim up or trim down) can
cause boat instability and can make steering the boat more difficult. This increases
the possibility of an accident. If the boat
begins to feel unstable or is hard to steer,
slow down and/or readjust the trim angle.
The trim angle of the outboard motor helps
determine the position of the bow of the boat
in the water. Correct trim angle will help improve performance and fuel economy while
reducing strain on the engine. Correct trim angle depends upon the combination of boat,
engine, and propeller. Correct trim is also affected by variables such as the load in the

EMU41081
Adjusting boat trim
When the boat is on plane, a bow-up attitude
results in less drag, greater stability and efficiency. This is generally when the keel line of
the boat is up about 3 to 5 degrees. With the
bow up, the boat may have a greater tendency to steer to one side or the other. Compensate for this as you steer. When the bow of the
boat is down, it is easier to accelerate from a
standing start onto plane.
ZMU07038
Bow Up
Too much trim-out puts the bow of the boat
too high in the water. Performance and economy are decreased because the hull of the
boat is pushing the water and there is more air
drag. Excessive trim-out can also cause the
propeller to ventilate, which reduces performance further, and the boat may “porpoise”
(hop in the water), which could throw the operator and passengers overboard.
U6CB10E0.book Page 61 Wednesday, September 30, 2009 9:49 AM
Operation
ZMU07039
Bow Down
Too much trim-in causes the boat to “plow”
through the water, decreasing fuel economy
and making it hard to increase speed. Operating with excessive trim-in at higher speeds
also makes the boat unstable. Resistance at
the bow is greatly increased, heightening the
danger of “bow steering” and making operation difficult and dangerous.

Transporting and storing outboard motor
EWM02551
WARNING
●
●
Leaking fuel is a fire hazard. When transporting and storing the outboard motor,
close the fuel cock to prevent fuel from
leaking.
Never get under the outboard motor
while it is tilted, even when the tilt support shaft is installed. Severe injury
could occur if the outboard motor accidentally falls.
The outboard motor should be trailered and
stored in the fully tilted-down position. If the
outboard motor cannot be trailered in the fully
tilted-down position, the outboard motor must
be secured in the tilted-up position using a
support device, such as the Yamaha Trailering Support.
EMU41001
Storing outboard motor
When storing your Yamaha outboard motor
for prolonged periods of time (2 months or
longer), several important procedures must
be performed to prevent excessive damage. It
is advisable to have your outboard motor serviced by an authorized Yamaha dealer prior to
storage. However, you, the owner, with a minimum of tools, can perform the following procedures.
ECM02281
NOTICE
Store the outboard motor in a dry, wellventilated place, not in direct sunlight.
fuel tank(s). If it is not possible to remove the
gasoline, add one ounce of “Yamalube Fuel
Stabilizer & Conditioner Plus” to each gallon
of gasoline in a full tank of gasoline to provide
fuel stability and corrosion protection.
TIP:
Do not fill the fuel tank(s) to the point of overflowing. Approximately 7/8 full will allow
enough space in the fuel tank to prevent gasoline purging from the fuel tank vent due to expansion with temperature changes.
Do not cap the fuel tank vent. Excessive pressure could damage the boat and motor’s fuel
systems.
A partially filled fuel tank, less than 7/8 full but
not completely empty, is not recommended.
Air space above the gasoline allows air movement which can bring in water through condensation as the air temperature changes.
Condensation inside the fuel tank can cause
corrosion problems and phase separation of
gasoline containing ethanol.
Consult your Yamaha dealer concerning preventative measures that may work best for the
gasoline and environmental conditions in your
area.

Periodic maintenance
EWM02480
WARNING
These procedures require mechanical
skills, tools, and supplies. If you do not
have the proper skills, tools, or supplies to
perform a maintenance procedure, have a
Yamaha dealer or other qualified mechanic do the work.
The procedures involve disassembling
the outboard motor and exposing dangerous parts. To reduce the risk of injury from
moving, hot, or electrical parts:
●
●
Unless otherwise specified, stop the engine and keep the key and engine shutoff cord (lanyard) with you when you
perform maintenance.
The power trim and tilt switches operate
even when the main switch is turned to
the “
” (off) position. Keep people
away from the power trim and tilt switches whenever working around the outboard motor. When the outboard motor
is tilted, keep away from the area under
it or between it and the clamp bracket.
Make sure that no one is in this area before operating the power trim and tilt
mechanism.
Allow the engine to cool before handling
hot parts or fluids.
Always assemble the outboard motor
completely before operating it.
Maintenance, replacement, or repair of the
emission control devices and system may
be performed by any marine engine repair
establishment or individual. All warranty
repairs; however, including those to the
emission control system, must be performed by an authorized Yamaha marine
dealership.
A service manual is available for purchase
through your Yamaha dealer for owners who
have the mechanical skills, tools, and other
equipment necessary to perform maintenance not covered by this owner’s manual.

EMU35521
Maintenance interval guidelines
The service intervals provided in the Maintenance Chart were developed based upon
“typical” use that includes operating at varied
speeds, with sufficient time for engine warm
up and cool-down, a medium to light load, and
an average cruising speed near the 3000 to
4000 rpm range. As with any engine, however, if your normal operating conditions are different, you should consider service more
often than shown, especially how often you
change your engine oil and gear oil. Examples might include extended wide-open-throttle use or long periods of trolling or idling,
carrying heavy loads, or frequent starting and
stopping or shifting. More frequent maintenance will often pay off many times over in increased engine life and greater owner
satisfaction. Consult your Yamaha dealer for
additional maintenance recommendations.

Inspecting spark plug
The spark plug is an important engine component. The condition of the spark plug can indicate something about the condition of the
engine. For example, if the center electrode
porcelain is very white, this could indicate an
intake air leak or carburetion problem in that
cylinder. Do not attempt to diagnose any
problems yourself. Instead, take the outboard
motor to a Yamaha dealer. You should periodically remove and check the spark plug because heat and deposits will cause the spark
plug to slowly break down and erode.
To remove the spark plug
1. Remove the flywheel magnet cover.
Remove the bolt that is securing the ignition coil, and then remove the ignition
coil. NOTICE: Do not use any tools to
remove or install the ignition coil. Otherwise, the ignition coil coupler could
be damaged. [ECM02330]
