SAFETY
INFORMATION
8 Before mounting or operating the out-
board motor, read this entire manual.
Reading it should give you an understanding of the motor and its operation.
8 Before operating the boat, read any
owner’s or operator’s manuals supplied
with it and all labels. Be sure you understand each item before operating.
8 Do not overpower the boat with this
outboard 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.
8 Do not modify the outboard. Modifica-
tions could make the motor unfit or
unsafe to use.
8 Never operate after drinking alcohol or
taking drugs. About 50% of all boating
fatalities involve intoxication.
8 Have an approved personal flotation
device (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 conditions.
8 Gasoline is highly flammable, and its
vapors are flammable and explosive.
Handle and store gasoline carefully.
Make sure there are no gas fumes or
leaking fuel before starting the engine.
8 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.
8 Check throttle, shift, and steering for
proper operation before starting the
engine.
8 Attach the engine stop switch lanyard
to a secure place on your clothing, or
your arm or leg while operating. If you
accidentally leave the helm, the lanyard
will pull from the switch, stopping the
engine.
8 Know the marine laws and regulations
where you will be boating - and obey
them. Refer to the “RULES OF THE
ROAD” section for basic boating rules.
8 Stay informed about the weather.
Check weather forecasts before boating.
Avoid boating in hazardous weather.
8 Tell someone where you are going:
leave a Float Plan with a responsible
person. Be sure to cancel the Float Plan
when you return.
8 Use common sense and good judgment
when boating. Know your abilities, and
be sure you understand how your boat
handles 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.
8 Always watch carefully for swimmers
during the engine operation.
8 Stay away from swimming areas.

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 agencies. 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 provided for your convenience only.
Consult your local U.S. Coast Guard Auxiliary or Department of Motor Vehicles for
a complete set of rules governing the
waters in which you will be using your
boat.
STEERING AND SAILING RULES AND
SOUND SIGNALS
Whenever two vessels on the water meet
one another, one vessel has the right-ofway; it is called the “stand-on” vessel.
The vessel which does not have the rightof-way is called the “give-way” or “bur-
dened” 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 rightof-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 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.
E
1-8
EE
102045
102044
102046
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
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-ofway 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 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 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
1-9
E
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.
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 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 which are fishing with nets,
lines or trawls are considered to be “fish-
ing 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 powerdriven 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
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
E
1-10
E
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.

PROPELLER SELECTION
The performance of your outboard motor
will be critically affected by your choice of
propeller, 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
propellers 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 suitable as it enables
the correct engine speed to be maintained. Conversely, a larger-pitch propeller is more suitable for a smaller operating 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 application.
1-15
E
NOTE:
At full throttle and under a maximum
boat load, the engine’s rpm should be
within the upper half of the full throttle
operating range, as listed in “SPECIFICA-
TIONS” on page 4-1. Select a propeller
which fulfills this requirement.
If operating under conditions which allow
the engine’s rpm to rise above the maximum recommended range (such as light
boat loads), reduce the throttle setting to
maintain the rpm in the proper operating
range.

functioning.
8 Avoid accidentally pulling the lanyard
during normal operation. Loss of
engine power means the loss of most
