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.
EMU40272
Rotating parts
Hands, feet, hair, jewelry, clothing, personal flotation device
(PFD) straps, etc., can become entangled with internal rotat-
ing parts of the engine, resulting in serious injury or death.
Keep the top cowling in place whenever possible. Do not re-
move or replace the top cowling with the engine running.
Only operate the engine with the top cowling removed ac-
cording 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 motor 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 mecha-
nism.
The power trim and tilt switches operate even when the main
switch is off. Keep people be away from the switches when-
ever 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 pre-
vents 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 re-
move 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 explo-
sive. Always, refuel according to the procedure on page 36
to reduce the risk of fire and explosion.
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. Nev-
er 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 pre-
cautions that you should follow when boating.
EMU33711
Alcohol and drugs
Never operate after drinking alcohol or taking drugs. Intoxi-
cation 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 neu-
tral 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 acceler-
ating 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.
EMU33763
Overloading
Do not overload the boat. Consult the boat capacity plate or
boat manufacturer for maximum weight and number of pas-
sengers. Be sure that weight is properly distributed accord-
ing to the boat manufacturer’s instructions. Overloading or
incorrect weight distribution can compromise the boat’s
handling and lead to an accident, capsizing or swamping.
EMU33773
Avoid collisions
Scan constantly for people, objects, and other boats. Be
alert for conditions that limit your visibility or block your vi-
sion 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 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.
EMU33791
Weather
Stay informed about the weather. Check weather forecasts
before boating. Avoid boating in hazardous weather.
EMU44161
Accident reporting
Boat operators are required by law to file a Boating Accident
Report with their 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 nec-
essary.
EMU44172
Boat education and training
For U.S.A.
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 Internet-based 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 Adminis-
trators (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.
For Canada
All operators of pleasure craft must illustrate competency by
means of a Pleasure Craft Operators Card with the excep-
tion of Personal Water Craft used for rental purposes which
require a rental checklist be completed. Pleasure Craft Op-
erators Cards can be obtained following the completion of a
competency course, with an online option. Details can be
found on Transport Canada’s website. www.tc.gc.ca
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 organi-
zations.
EMU33592
Laws and regulations
Know the marine laws and regulations where you will be
boating—and obey them. Several sets of rules prevail ac-
cording to geographic location, but all are basically the same
as the International Rules of the Road. The rules presented
in the following section are condensed—and have been pro-
vided for your convenience only.
Contact the U.S. Coast Guard, the National Association of
State Boating Law Administrators, or your local Power
Squadron for a complete set of rules governing the waters in
which you will be using your boat.

EMU33692
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 inter-
nationally. (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 encoun-
ter another vessel on the water.
EMU33702
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” ves-
sel. The vessel that does not have the right-of-way is called
the “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 ves-
sel will be able to determine how best to avoid you.
Give-way vessel
The vessel that does not have the right-of-way 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 dan-
ger.”
In other words, follow the standard rules except when a col-
lision will occur unless both vessels try to avoid each other.
If that is the case, both vessels become “Give-Way” vessels.
EMU25524
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:
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 shad-
ed area must yield to you (they are the Give-Way vessels).
Both you and the meeting vessel must alter course to avoid
each other.

Safety information

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 an-
other if you continue on your set course and speed.
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 oth-
er 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 main-
tain 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.
EMU47290
Other special situations
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 power-driven 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 sec-
onds). 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 con-
sidered 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 nav-
igate only in such a channel.
Reading buoys and other markers
The waters of the United States are marked for safe naviga-
tion 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 mark-
ings on these buoys are oriented from the perspective of be-
ing entered from seaward (the boater is going towards the
port). This means that red buoys are passed on the star-
board (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 Water-
way 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. Al-
ways consult local boating authorities before driving your
boat in unfamiliar waters.
