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 be-
come entangled with internal rotating parts of
the engine, resulting in serious injury or
death.
Keep the top cowling in place whenever pos-
sible. Do not remove or replace the top cowl-
ing with the engine running.
Only operate the engine with the top cowling
removed according to the specific instruc-
tions 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 en-
gine has cooled.
EMU33651
Electric shock
Do not touch any electrical parts while start-
ing 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 peo-
ple be away from the switches whenever
working around the motor.
Never get under the lower unit while it is tilt-
ed, even when the tilt support lever is locked.
Severe injury could occur if the outboard mo-
tor accidentally falls.
EMU41252
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 at-
tach the engine shut-off cord to clothing that
could tear loose, or route the engine shut-off
cord where it could become entangled, pre-
venting 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 opera-
tion, 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 flam-
mable and explosive. Always, refuel ac-

cording to the procedure on page 61 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, immedi-
ately wash with soap and water. Change
clothing if gasoline spills on it.
If you swallow gasoline, inhale a lot of gaso-
line 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 con-
tain 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 mo-
tor. 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 im-
portant 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 com-
mon 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 wa-
ter, 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 instruc-
tions for details about appropriate passenger
locations in your boat and be sure all pas-
sengers are positioned properly before ac-
celerating 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 direc-
tion. Even when people are positioned prop-
erly, alert your passengers if you must make
any unusual maneuver. Always avoid jump-
ing waves or wakes.
EMU33762
Overloading
Do not overload the boat. Consult the boat
capacity plate or boat manufacturer for max-
imum weight and number of passengers. Be
sure that weight is properly distributed ac-
cording to the boat manufacturer’s instruc-
tions. Overloading or incorrect weight
distribution can compromise the boats han-

dling and lead to an accident, capsizing or
swamping.
EMU33773
Avoid collisions
Scan constantly for people, objects, and oth-
er 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, ob-
jects, 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 un-
derstand 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.
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 in-
volved 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.
EMU44171
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 cours-
es 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 Administrators (NASBLA) and recog-
nized 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 over-
view of the basics in boating safety, require-
ments, navigation, and operation. Upon
successful completion of the course, the
user can download a certificate of comple-
tion immediately or, for a small charge, re-

For Canada
All operators of pleasure craft must illustrate
competency by means of a Pleasure Craft
Operators Card with the exception of Per-
sonal Water Craft used for rental purposes
which require a rental checklist be complet-
ed. Pleasure Craft Operators Cards can be
obtained following the completion of a com-
petency course, with an on-line option. De-
tails 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 organizations.
EMU33591
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. The rules
presented in the following section are con-
densed- and have been provided for your
convenience only.
Contact the U.S. Coast Guard, the National
Association of State Boating Law Adminis-
trators, 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 en-
forced 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.
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” vessel. 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
vessel 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 brief-
ly 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 naviga-
tion and collision, and to any special circum-
stances, which may render a departure from
the above rules necessary in order to avoid
immediate danger.”
In other words, follow the standard rules ex-
cept when a collision will occur unless both
vessels try to avoid each other. If that is the
case, both vessels become “Give-Way” ves-
sels.
EMU25522
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 ves-
sel head-on)
6CE-9-37-1E0.book 5 ページ ２０１５年１１月１８日 水曜日 午前１１時４３分

Safety information
6
Crossing: (you are traveling across the oth-
er 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.
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 ves-
sel 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.
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 oth-
er 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 direc-
tion, 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 an-
other vessel is passing you, you should
maintain your speed and direction so that the
other vessel can steer itself around you.
EMU25532
Other special situations
There are three other rules you should be
aware of when driving your boat around oth-
er vessels.
Narrow channels and bends
When navigating in narrow channels, you
should keep to the right when it is safe and

bend that may obstruct the view of other wa-
ter vessels, the operator should sound a pro-
longed 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 pro-
ceed 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 ves-
sels. Fishing vessels have the right-of-way
regardless of position. Fishing vessels can-
not, 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.
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 navigat-
ing in a particular direction. The markings on
these buoys are oriented from the perspec-
tive of being entered from seaward (the boat-
er is going towards the port). This means that
red buoys are passed on the starboard
(right) side when proceeding from open wa-
ter into port, and black buoys are to port (left)
side. When navigating out of port, your posi-
tion with respect to the buoys should be re-
versed; 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 dis-
tinctive 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 geo-
graphic location. Always consult local boat-
ing authorities before driving your boat in
unfamiliar waters.
