Safety information

EMU33622

Outboard motor safety

Observe these precautions at all times.

EMU36500

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.

●

Shut off 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.

EMU33630

Rotating parts

Hands, feet, hair, jewelry, clothing, 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 cowling
with the engine running.
Only operate the engine with the 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.

EMU33660

Power trim and tilt

Body parts can be crushed between the mo-

tor and the clamp bracket when the motor is
trimmed or tilted. Keep body parts out of this
area at all times. Be sure 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 off. Keep peo­ple be away from the switches whenever
working around the motor.
Never get under the lower unit while it is tilt­ed, even when the tilt support lever is locked.
Severe injury could occur if the outboard mo­tor accidentally falls.

EMU33671

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 cord to clothing that could tear
loose, or route the cord where it could be­come entangled, preventing it from function­ing.
Do not route the cord where it is likely to be
accidentally pulled out. If the 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.

cording to the procedure on page 37 to
reduce the risk of fire and explosion.

Always, refuel ac-

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.

EMU33720

Personal flotation devices

Have an approved personal flotation device
(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 wear
PFDs, and everyone should wear PFDs
when there are potentially hazardous boat­ing conditions.

EMU33730

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 shut off the motor.
Stay away from swimming areas. Swimmers
can be hard to see.
The propeller can keep moving even when
the motor is in neutral. Shut off the engine
when a person is in the water near you.

EMU33750

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 han-

dling and lead to an accident, capsizing or
swamping.

EMU33771

Avoid collisions

Scan constantly

other boats. Be alert for conditions that limit
your visibility or block your vision of others.

Operate defensively

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

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.

at safe speeds and

to avoid collisions. Re-

boats do not have brakes

, and

Weather

Stay informed about the weather. Check
weather forecasts before boating. Avoid

boating in hazardous weather.

EMU33880

Passenger training

Make sure at least one other passenger is
trained to operate the boat in the event of an
emergency.

EMU33890

Boating safety publications

Be informed about boating safety. Additional
publications and information can be obtained
from many boating organizations.

EMU33600

Laws and regulations

Know the marine laws and regulations where
you will be boating- and obey them. Several
sets of rules prevail according to geographic
location, but all are basically the same as the
International Rules of the Road.

Propeller selection

Next to selecting an outboard, choosing 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 outboard motor came with a Yamaha
propeller chosen to perform well over a
range of applications, but there may be uses
where a different propeller would be more
appropriate.
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, chose a larger pitch propel-

ler for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that vary widely, chose 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.
For instructions on propeller removal and in­stallation, see page 65.

Anti-fouling paint

A clean hull improves boat performance. The
boat bottom should be kept as clean of ma­rine growth as possible. If necessary, the
boat bottom can be coated with an anti-foul­ing paint approved for your area to inhibit
marine growth.
Do not use anti-fouling paint which includes
copper or graphite. These paints can cause
more rapid engine corrosion.

The clip must be attached to the engine shut­off switch for the engine to run. The cord
should be attached to a secure place on the
operator’s clothing, or arm or leg. Should the
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.

tach 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 en-

WARNING! At-

tangled, preventing it from functioning.
Avoid accidentally pulling the cord dur­ing normal operation. Loss of engine
power means the loss of most steering
control. Also, without engine power, the
boat could slow rapidly. This could cause
people and objects in the boat to be
thrown forward.
