Safety information

Before mounting or operating the outboard
motor, read this entire manual. Reading it
should give you an understanding of the
motor and its operation.
Before operating the boat, read any own-
er’s or operator’s manuals supplied with it
and all labels. Be sure you understand
each item before operating.
Do not overpower the boat with this out-
board motor. Overpowering the boat could
result in loss of control. The rated power of
the outboard should be equal to or less
than the rated horsepower capacity of the
boat. If the rated horsepower capacity of
the boat is unknown, consult the dealer or
boat manufacturer.
Do not modify the outboard. Modifications
could make the motor unfit or unsafe to
use.
Never operate after drinking alcohol or tak-
ing drugs. About 50% of all boating fatali-
ties involve intoxication.
Have an approved personal flotation de-
vice (PFD) on board for every occupant. It
is a good idea to 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 condi-
tions.
Gasoline is highly flammable, and its va-
pors are flammable and explosive. Handle
and store gasoline carefully. Make sure
there are no gas fumes or leaking fuel be-
fore starting the engine.
This product emits exhaust gases which
contain carbon monoxide, a colorless,
odorless gas which may cause brain dam-
age or death when inhaled. Symptoms in-
clude nausea, dizziness, and drowsiness.
Keep cockpit and cabin areas well ventilat-
ed. Avoid blocking exhaust outlets.
Check throttle, shift, and steering for prop-
er operation before starting the engine.
Attach the engine stop switch lanyard cord
to a secure place on your clothing, or your
arm or leg while operating. If you acciden-
tally leave the helm, the cord will pull from
the switch, stopping the engine.
Know the marine laws and regulations
where you will be boating—and obey
them. For basic boating rules, see “Rules

of the road” on page 5.
Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
Tell someone where you are going: leave
a Float Plan with a responsible person. Be
sure to cancel the Float Plan when you re-
turn.
Use common sense and good judgment
when boating. Know your abilities, and be
sure you understand how your boat han-
dles under the different boating conditions
you may encounter. Operate within your
limits, and the limits of your boat. Always
operate at safe speeds, and keep a careful
watch for obstacles and other traffic.
Always watch carefully for swimmers dur-
ing the engine operation.
Stay away from swimming areas.
When a swimmer is in the water near you
shift into neutral and shut off the engine.

Basic boating rules (Rules of
the road)
Just as there are rules which apply when you
are driving on streets and high ways, there
are waterway rules which apply when you
are driving your boat. These rules are used
internationally, and are also enforced by the
United States Coast Guard and local agen-
cies. You should be aware of these rules,
and follow them whenever you encounter
another vessel on the water.
Several sets of rules prevail according to
geographic location, but are all basically the
same as the International Rules of the Road.
The rules presented here in your Owner’s
Manual are condensed, and have been pro-
vided for your convenience only. Consult
your local U.S. Coast Guard Auxiliary or De-
partment of Motor Vehicles for a complete
set of rules governing the waters in which
you will be using your boat.
EMU25510
Steering and sailing rules and sound
signals
Whenever two vessels on the water meet
one another, one vessel has the right-of-
ZMU04435
General information
6
way; it is called the “stand-on” vessel. The
vessel which 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 which 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.
EMU25520
Rules when encountering vessels
There are three main situations which 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)
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.
General information
7
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.
EMU25530
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
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 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 which are fishing with nets, lines
or trawls are considered to be “fishing ves-
sels” 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-driv-
en 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 which can navi-
gate only in such a channel.
General information

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 regulato-
ry or advisory information. These markers
are white with black letters and orange
boarders. They signify speed zones, restrict-
ed areas, danger areas, and general infor-
mation.
Remember, markings may vary by geo-
graphic location. Always consult local boat-
ing authorities before driving your boat in
unfamiliar waters.

Fueling instructions
WARNING
EWM00010
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!
Do not smoke when refueling, and keep
away from sparks, flames, or other
sources of ignition.
Stop engine before refueling.
Refuel in a well-ventilated area. Refuel
portable fuel tanks off the boat.
Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
ZMU01708
General information

dry rags.
Do not overfill the fuel tank.
Tighten the filler cap securely after re-
fueling.
If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
If any gasoline spills onto your skin, im-
mediately wash with soap and water.
Change clothing if gasoline spills on it.
Touch the fuel nozzle to the filler open-
ing or funnel to help prevent electro-
static sparks.
CAUTION:
ECM00010
Use only new clean gasoline which has
been stored in clean containers and is not
contaminated with water or foreign mat-
ter.
EMU25570
Gasoline
If knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing metha-
nol. Gasohol containing ethanol can be used
if ethanol content does not exceed 10% and
the fuel meets minimum octane ratings.
Yamaha does not recommended gasohol
containing methanol because it can cause
fuel system damage or engine performance
problems.
EMU25660
Engine oil
Use Yamalube 2-M outboard oil. If Ya-
malube 2-M is not available, use only anoth-
er outboard motor manufacturer’s factory-
brand oil with TC-W3 rating.
CAUTION:
ECM01290
Serious engine damage can result from
the use of lower quality oil, including
some commonly available oil brands with
“TC-W3” on their label. To avoid the risk,
use only Yamalube 2-M or, if necessary,
another outboard motor manufacturer’s
factory-brand TC-W3 oil.
EMU25700

Battery requirement

CAUTION:
ECM01060
Do not use a battery that does not meet
the specified capacity. If a battery which
does not meet specifications is used, the
electric system could perform poorly or
be overloaded, causing electric system
damage.
For electric start models, choose a battery
which meets the following specifications.
Recommended gasoline:
Regular unleaded gasoline with a min-
imum octane rating of 86 (Pump Oc-
tane Number) = (R+M)/2
Recommended engine oil:

EMU25741

Propeller selection

The performance of your outboard motor will
be critically affected by your choice of propel-
ler, as an incorrect choice could adversely
affect performance and could also seriously
damage the motor. Engine speed depends
on the propeller size and boat load. If engine
speed is too high or too low for good engine
performance, this will have an adverse effect
on the engine.
Yamaha outboard motors are fitted with pro-
pellers chosen to perform well over a range
of applications, but there may be uses where
a propeller with a different pitch would be
more appropriate. For a greater operating
load, a smaller-pitch propeller is more suit-
able as it enables the correct engine speed
to be maintained. Conversely, a larger-pitch
propeller is more suitable for a smaller oper-
ating load.
Yamaha dealers stock a range of propellers,
and can advise you and install a propeller on
your outboard that is best suited to your ap-
plication.
NOTE:
Select a propeller which will allow the engine
to reach the middle or upper half of the oper-
ating range at full throttle with the maximum
boat load. If operating conditions such as
light boat loads then allow the engine r/min to
rise above the maximum recommended
range, reduce the throttle setting to maintain
the engine in the proper operating range.
For instructions on propeller removal and in-
stallation, see page 61.
EMU25770

Start-in-gear protection

Yamaha outboard motors or Yamaha-ap-
proved remote control units are equipped
with start-in-gear protection device(s). This
feature permits the engine to be started only
when it is in neutral. Always select neutral
before starting the engine.

Remote control lever
Moving the lever forward from the neutral po-
sition engages forward gear. Pulling the le-
ver back from neutral engages reverse. The
engine will continue to run at idle until the le-
ver is moved about 35° (a detent can be felt).
Moving the lever farther opens the throttle,
and the engine will begin to accelerate.

ting.
EMU25990

Engine stop lanyard switch

The lock plate must be attached to the en-
gine stop switch for the engine to run. The
lanyard 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 lanyard will pull out the lock
plate, stopping ignition to the engine. This
will prevent the boat from running away un-
der power.
WARNING
EWM00120
Attach the engine stop switch lanyard
to a secure place on your clothing, or
your arm or leg while operating.
Do not attach the lanyard to clothing
that could tear loose. Do not route the
lanyard where it could become entan-
gled, preventing it from functioning.
Avoid accidentally pulling the lanyard
during normal operation. Loss of en-
gine 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.
NOTE:
The engine cannot be started with the lock
plate removed.

Trim tab with anode
The trim tab should be adjusted so that the
steering control can be turned to either the
right or left by applying the same amount of
force.
WARNING
EWM00840
An improperly adjusted trim tab could
cause difficult steering. Always test run
after the trim tab has been installed or re-
placed to be sure steering is correct. Be
sure you have tightened the bolt after ad-
justing the trim tab.
If the boat tends to veer the left (port side),
turn the trim tab rear end to the port side A
in the figure. If the boat tends to veer the right
(starboard side), turn the trim tab end to the
starboard side B in the figure.
CAUTION:
ECM00840
The trim tab also serves as an anode to
protect the engine from electrochemical
corrosion. Never paint the trim tab as it
will become ineffective as an anode.
