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 wa-
ter 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.
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. Always, refuel accord-
ing to the procedure on page 28 to reduce the
risk of fire and explosion.
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.

Safety information
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.
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.
EMU33772
Avoid collisions
Scan constantly for people, objects, and other
boats. Be alert for conditions that limit your
visibility or block your vision of others.
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.
2
Safety information
● 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. 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.
EMU33790
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.

dealer.
EMU34194
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
9
Specifications and requirements
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 56.

Throttle friction adjuster
The throttle friction adjuster provides adjustable resistance when the throttle grip is
turned, and can be set according to operator
preference.
To increase resistance, turn the throttle friction adjuster clockwise.
To decrease resistance, turn the throttle friction adjuster counterclockwise. When constant speed is desired, tighten the throttle
friction adjuster to maintain the desired throttle setting. WARNING! Do not overtighten
the throttle friction adjuster. If there is too
much resistance, it could be difficult to
turn the throttle grip, which could result in
an accident.

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.
