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 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 top cowling with the engine running.
Only operate the engine with the top 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 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
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.

Safety information
EMU33811
Gasoline
Gasoline and its vapors are highly flammable and explosive. Always, refuel according
to the procedure on page 59 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. 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 instruc-
2
Safety information
ZMU06025
tions. Overloading or incorrect weight
distribution can compromise the boats 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 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.
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 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 courses in
your area.
You may also want to consider an Internetbased 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 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
3
Safety information
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 exception of Personal Water Craft used for rental purposes which
require a rental checklist be completed. Pleasure Craft Operators Cards can be obtained
following the completion of a competency
course, with an on-line 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 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 condensed- and have been provided 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 internationally. (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 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-ofway 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 danger.”
In other words, follow the standard rules except when a collision will occur unless both
vessels try to avoid each other. If that is the
case, both vessels become “Give-Way” vessels.
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 vessel head-on)
5
Safety information
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.
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 r ule d oes n’t a pply
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 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 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.
EMU25532
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 powerdriven vessel is preparing to go around a
bend that may obstruct the view of other wa-
6
Safety information
ter vessels, the operator should sound a prolonged 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 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 considered 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 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 navigating in a particular direction. The markings on
these buoys are oriented from the perspective of being 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 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 Waterway 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. Always consult local boating authorities before driving your boat in unfamiliar
waters.

life. Yamaha designs and manufactures propellers for every Yamaha outboard motor and
every application.
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.
Yamaha recommends to use a propeller suitable for the “Shift Dampener System (SDS)”.
For further information, consult your Yamaha
dealer.

Counter rotation models
Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclockwise and are typically used in multiple motor
setups.
On counter rotation models, be sure to use a
propeller intended for counterclockwise rotation. These propellers are identified with the
letter “L” after the size indication on the propeller. WARNING! Never use a standard
propeller with a counter rotation motor, or
a counter rotation propeller with a standard motor. Otherwise the boat could go
in the direction opposite of that expected
(for example, reverse instead of forward),
which could lead to an accident.
For instructions on propeller removal and installation, see page 85.

Fuel requirements
EMU44791
Gasoline
Use a good quality gasoline that meets the
minimum octane requirement. If knocking or
pinging occurs, use a different brand of gasoline or premium unleaded fuel. Yamaha recommends that you use alcohol-free gasoline
(see Gasoline with Ethanol) whenever possible.
The use of a poor quality gasoline may result
in starting and running problems. If you encounter drivability problems, which you suspect could be related to the fuel you are
using, Yamaha recommends that you switch
to a recognized high quality brand of gasoline, such as a gasoline that is advertised as
Top Tier Detergent Gasoline. (North America
only) NOTICE: Failure to comply with these
recommendations may also result in unscheduled maintenance, fuel system damage, and internal engine damage.

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.
Gasoline with Ethanol
Two types of gasoline are commonly available in the U.S.A., Canada, Australia and
New Zealand for use in automobiles and
boats: conventional gasoline without Ethanol
and gasoline with Ethanol, which is typically
referred to as E10 gasoline. According to federal regulations, E10 gasoline may contain up
to 10% Ethanol.
A high quality gasoline without Ethanol is the
preferred fuel for your Yamaha outboard motor. However, if gasoline with Ethanol is the
only fuel available in your area, your Yamaha
outboard motor is calibrated to run properly
on fresh E10 gasoline that meets the minimum octane requirement specified for this
model.
ECM02402
Never use a gasoline for your outboard
motor that contains more than 10% Ethanol, such as E15 which contains 15% Ethanol or E85 which contains 85% Ethanol,
or gasoline containing any amount of
Methanol. These fuels can cause starting
and running problems, as well as serious
fuel system and internal engine damage.
Gasoline containing ethanol has several
properties that may cause boat fuel system
problems.
Ethanol is a strong solvent (cleaning agent)
that can clean gum and varnish deposits
from a boat’s fuel system, particularly in
older boats, as well as tanks and pipes
used in gasoline distribution. These released deposits contaminate the fuel and
can cause problems, such as clogged fuel
filters, carburetors, or fuel injectors, which
could result in engine damage.
Ethanol may dissolve resins used in the
construction of fiberglass fuel tanks. The
dissolved resins contaminate the fuel and
can cause problems, such as clogged fuel
filters, carburetors, or fuel injectors, which
could result in engine damage.
Ethanol is hygroscopic (has a strong at-
traction to water). Therefore, any water that
inadvertently enters the fuel system, including moisture that is absorbed from the
air, will mix with the ethanol in the gasoline.
If the amount of water is excessive, the ethanol and water mixture will separate from
the gasoline in a layer at the bottom of the
fuel tank. This ethanol and water mixture is
very corrosive to aluminum fuel tanks and
fuel system components.
The usable life span of E10 gasoline may
be shorter than the normal length of offseason boat storage, causing starting and
running problems related to stale fuel.
For more information on using fuel containing
ethanol, visit: http://www.yamaha-motor.com

Specifications and requirements
NOTICE
Gasoline Filtration
Yamaha outboard motors are equipped with
internal fuel filters. However, excessive water
or debris entering your engine’s fuel system
could prematurely clog the internal filters,
causing starting and running problems, fuel
system damage, and internal engine damage. Therefore, it is recommended that an external 10-micron water-separating fuel filter
be installed on your boat and serviced frequently. Consult your authorized Yamaha
dealer for a 10-micron filter that meets your
engine’s requirements.
EMU41342
Gasoline Additives
Gasoline blends change to meet automobile
emission regulations and economic conditions. Additives, added by gasoline distributors, necessary for proper automobile engine
operation and durability, may not be sufficient for typical boat applications. Intake
valve and combustion chamber deposits
may accumulate in boat engines more rapidly
than encountered in automotive use. In addition, gasoline used for boating will typically
age longer between refills than gasoline used
in automobiles, resulting in stale and unusable gasoline that may cause starting and
running problems, fuel system damage, and
internal engine damage.
Yamaha recommends the use of two Yamalube gasoline additives to reduce internal deposits and extend the storage life of gasoline.
Continuous use of Yamalube Ring Free Fuel
Additive Plus reduces harmful internal deposits. Yamalube Fuel Stabilizer & Conditioner Plus added to fresh gasoline will help
protect the fuel system from varnishing while
helping to keep the gasoline’s octane level
from decreasing excessively during storage.
Other additives may also be available on the
market that may have varying degrees of ef-
fectiveness. Consult your Yamaha dealer
concerning what may work best for the locally available gasoline and environmental conditions.
EMU36881
Muddy or acidic water
Yamaha strongly recommends that you have
your dealer install the optional chromiumplated water pump kit if you use the outboard
motor in muddy or acidic water conditions.
However, depending on the model it might
not be required.
EMU41354
Anti-fouling paint
A clean hull is required to maintain your
boat’s performance. Boats moored in the water should be protected from marine growth
(barnacles, mussels, and marine plants). If
approved by regulations for your area, the
bottom of the hull can be coated with an antifouling paint to inhibit marine growth.
Anti-fouling paints specifically formulated for
use on aluminum may be applied to the outboard motor. The original Yamaha paint surface may be scuffed lightly before applying
anti-fouling paint, but do not remove the original paint. Removal of the original paint will increase the rate of corrosion.
ECM04821
Anti-fouling paint for fiberglass and
wood may contain materials, such as
copper, graphite, and tin, that can cause
corrosion if applied to aluminum boats
and outboard motor components. Never
apply these types of paint to your out-
board motor because rapid corrosion
damage could occur.
