SAFETY
INFORMATION
8Before mounting or operating the out-
board motor, read this entire manual.
Reading it should give you an under-
standing of the motor and its operation.
8Before operating the boat, read any
owner’s or operator’s manuals supplied
with it and all labels. Be sure you under-
stand each item before operating.
8Do 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 capaci-
ty of the boat. If the rated horsepower
capacity of the boat is unknown, consult
the dealer or boat manufacturer.
8Do not modify the outboard. Modifications
could make the motor unfit or unsafe to
use.
8Never operate after drinking alcohol or
taking drugs. About 50% of all boating
fatalities involve intoxication.
8Have an approved personal flotation
device (PFD) on board for every occu-
pant. It is a good idea to wear a PFD
whenever boating. At a minimum, chil-
dren and non-swimmers should always
wear PFDs, and everyone should wear
PFDs when there are potentially haz-
ardous boating conditions.
8Gasoline 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.
8This 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.
8Check throttle, shift, and steering for
proper operation before starting the
engine.
8Attach the engine stop switch lanyard to a
secure place on your clothing, or your
arm or leg while operating. If you acciden-
tally leave the helm, the lanyard will pull
from the switch, stopping the engine.
8Know 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.
8Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
8Tell someone where you are going: leave
a Float Plan with a responsible person.
Be sure to cancel the Float Plan when
you return.
8Use common sense and good udgment
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 care-
ful watch for obstacles and other traffic.
8Always watch carefully for swimmers dur-
ing the engine operation.
8Stay away from swimming areas.
8When 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
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-of-
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” ves-
sel. 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 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 eneral 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 ren-
der 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.
69L-9-12-1 3/5/02 5:00 PM Page 11

1-7
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:
Meetin (you are approaching another ves-
sel head-on)
Crossin (you are traveling across the
other vessel’s path)
Overtakin (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 meet-
ing vessel must alter course to avoid each
other.
Meetin
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.
Crossin
When two power driven vessels are cross-
ing 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.
Overtakin
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

E
1-8
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.
Fishin vessel ri ht-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.
Sailin vessel ri ht-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-dri-
ven 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.
Readin 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 sea-
ward (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 star-
board.
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,
restricted areas, danger areas, and general
information.
69L-9-12-1 3/5/02 5:00 PM Page 13

Remember, markings may vary by geo-
graphic location. Always consult local boat-
ing 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.

NOTE:
The engine cannot be started if battery volt-
age is too low.

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 pro-
pellers, and can advise you and install a
propeller on your outboard that is best suit-
ed to your application.
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 “SPECIFICATIONS” 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 maxi-
mum recommended range (such as light
boat loads), reduce the throttle setting to
maintain the rpm in the proper operating
range.
