Safety information
EMU33623
Outboard motor safety
Observe these precautions at all times.
EMU36502
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.
EMU33631
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.
EMU33641
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.
EMU33651
Electric shock
Do not touch any electrical parts while starting or operating the engine. They can cause
shock or electrocution.
EMU33661
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.
EMU33672
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.
EMU33811
Gasoline
Gasoline and its vapors are highly flammable and explosive. Always, refuel ac-
cording to the procedure on page 48 to
reduce the risk of fire and explosion.
1
Safety information
EMU33821
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.
EMU33901
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.
EMU33781
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.
EMU33741
Boating safety
This section includes a few of the many important safety precautions that you should
follow when boating.
EMU33711
Alcohol and drugs
Never operate after drinking alcohol or taking
drugs. Intoxication is one of the most common factors contributing to boating fatalities.
EMU40281
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 wear PFDs, and everyone
should wear PFDs when there are potentially
hazardous boating conditions.
EMU33732
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.
EMU33752
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.
EMU33762
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 manufacturer’s instructions. Overloading or incorrect weight
distribution can compromise the boats handling and lead to an accident, capsizing or
swamping.

Safety information
ZMU06025
EMU33773
Avoid collisions
Scan constantly for people, objects, and other boats. Be alert for conditions that limit your
visibility or block your vision of others.
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 aggres-
sive maneuvers to reduce the risk of loss
of control, ejection, and collision.
Take early action to avoid collisions. Re-
member, 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.
EMU33791
Weather
Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
EMU33881
Passenger training
Make sure at least one other passenger is
trained to operate the boat in the event of an
emergency.
EMU33891
Boating safety publications
Be informed about boating safety. Additional
publications and information can be obtained
from many boating organizations.
EMU33601
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 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 outboard motor came with a Yamaha
propeller selected 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, 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.
To check the propeller, see page 80.

Start-in-gear protection
Yamaha outboard motors or Yamaha-approved remote control units are equipped
with start-in-gear protection device(s). This
feature permits the engine to be started only
when it is in neutral. Always select neutral
before starting the engine.

Fuel requirements
EMU40202
Gasoline
Use a good quality gasoline that meets the
minimum octane rating. If knocking or pinging occurs, use a different brand of gasoline
or premium unleaded fuel.
Recommended fuel:
Regular unleaded gasoline
Min. research octane number (RON):
90
ECM01982
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.
Gasohol
There are two types of gasohol: gasohol containing ethanol (E10) and that containing
methanol. Ethanol can be used if the ethanol
content does not exceed 10% and the fuel
meets the minimum octane ratings. E85 is a
fuel containing 85% ethanol and must not be
used in your outboard motor. All ethanol
blends containing more than 10% ethanol
can cause fuel system damage or cause engine starting and running problems. Yamaha
does not recommend gasohol containing
methanol because it can cause fuel system
damage or engine performance problems.
It is recommended that you install a waterseparating marine fuel filter assembly (10 micron minimum) between your boat’s fuel tank
and outboard motor when using ethanol.
13
Specifications and requirements
Ethanol is known to allow moisture to be absorbed into boat fuel tanks and systems.
Moisture in the fuel can cause corrosion of
metallic fuel system components, starting
and running complaints and require additional fuel system maintenance.
EMU36331
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.
with clip.
Spare parts, such as an extra set of spark
plugs.
Consult your Yamaha dealer for details.

Engine shut-off cord (lanyard) and
clip
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. WARNING! At-
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 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, without engine power, the
boat could slow rapidly. This could cause
people and objects in the boat to be
thrown forward.
