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 neu-
tral, 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 inter-
nal rotating parts of the engine, resulting in se-
rious injury or death.
Keep the top cowling in place whenever pos-
sible. Do not remove or replace the cowling
with the engine running.
Only operate the engine with the cowling re-
moved according to the specific instructions in
the manual. Keep hands, feet, hair, jewelry,
clothing, PFD straps, etc. away from any ex-
posed 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 en-
gine has cooled.
EMU33650
Electric shock
Do not touch any electrical parts while starting
or operating the engine. They can cause
shock or electrocution.
EMU34790
Power 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 tilt mechanism.
The power 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 or knob is
locked. Severe injury could occur if the out-
board motor accidentally falls.
EMU33671
Engine shut-off cord (lanyard)
Attach the engine shut-off cord so that the en-
gine stops if the operator falls overboard or
leaves the helm. This prevents the boat from
running away under power and leaving peo-
ple stranded, or running over people or ob-
jects.
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 cord to clothing that could tear loose,
or route the cord where it could become en-
tangled, 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 ob-
jects forward.
EMU33810
Gasoline
Gasoline and its vapors are highly flam-
mable and explosive. Always, refuel accord-
ing to the procedure on page 48 to reduce the
risk of fire and explosion.
U6DR30E0.book Page 1 Friday, November 30, 2012 4:27 PM

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, 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.
EMU33900
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 ex-
haust outlets.
EMU33780
Modifications
Do not attempt to modify this outboard motor.
Modifications to your outboard motor may re-
duce safety and reliability, and render the out-
board unsafe or illegal to use.
EMU33740
Boating safety
This section includes a few of the many im-
portant safety precautions that you should fol-
low 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.
EMU40280
Personal flotation devices (PFDs)
Have an approved PFD on board for every oc-
cupant. 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 wa-
ter, such as swimmers, skiers, or divers,
whenever the engine is running. When some-
one 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 loca-
tions 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 loca-
tions may result in being thrown either over-
board 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 ca-
pacity plate or boat manufacturer for maxi-
mum weight and number of passengers. Be
sure that weight is properly distributed ac-
cording to the boat manufacturers instruc-
tions. Overloading or incorrect weight
distribution can compromise the boats han-
dling 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.
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 un-
derstand 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 con-
trol, 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 anoth-
er direction.
EMU33790
Weather
Stay informed about the weather. Check
weather forecasts before boating. Avoid boat-
ing in hazardous weather.
EMU44160
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 oth-
er property over a certain amount.
4. There is complete loss of a boat.
Contact local law enforcement personnel if a
report is necessary.
EMU44170
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 recognized by
the United States Coast Guard. Most, but not
all, states accept this course to meet their
minimum requirements. While it cannot re-
place an in-depth course such as one offered
by the U.S. Coast Guard, U.S. Power Squad-
ron, 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 certifi-
cate of completion immediately or, for a small
charge, request one by mail. To take this free
course, go to boatus.org.

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.
EMU33590
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 Administra-
tors, or your local Power Squadron for a com-
plete set of rules governing the waters in
which you will be using your boat.

EMU33691
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 driv-
ing your boat. These rules are used interna-
tionally. (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.
EMU33700
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 main-
tain 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 briefly and
pass behind the other vessel. You should al-
ways 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.
EMU25521
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 fol-
lowed:
Meeting: (you are approaching another ves-
sel 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 shaded
area must yield to you (they are the Give-Way
vessels). Both you and the meeting vessel
must alter course to avoid each other.
U6DR30E0.book Page 5 Friday, November 30, 2012 4:27 PM

Safety information
6
Meeting
If you are meeting another power vessel head
on, and are close enough to run the risk of col-
lision, neither of you has the right-of-way Both
of you should alter course to avoid an acci-
dent. You should keep the other vessel on
your port (left) side. This rule doesn’t apply if
both of you will clear one another if you con-
tinue 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, provid-
ed 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 another vessel is
passing you, you should maintain your speed
and direction so that the other vessel can
steer itself around you.
EMU25531
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 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 nav-
igate such waters with your boat, you will
need to carry a portable air horn, available
from local marine supply stores.
U6DR30E0.book Page 6 Friday, November 30, 2012 4:27 PM

Safety information
7
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 re-
gardless of position. Fishing vessels cannot,
however, impede the passage of other ves-
sels 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, num-
bers and lights to show which side of the buoy
a boater should pass on when navigating in a
particular direction. The markings 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 starboard (right) side when
proceeding from open water into port, and
black buoys are to port (left) side. When navi-
gating out of port, your position with respect to
the buoys should be reversed; red buoys
should be to port and black buoys to star-
board.
Many bodies of water used by boaters are en-
tirely 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 geograph-
ic location. Always consult local boating au-
thorities before driving your boat in unfamiliar
waters.
