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
owner’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 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.
●
Do not modify the outboard. Modifications
could make the motor unfit or unsafe to
use.
●
Never operate after drinking alcohol or
taking drugs. About 50% of all boating
fatalities involve intoxication.
●
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.
●
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.
●
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.
●
Check throttle, shift, and steering for
proper operation before starting the
engine.
●
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.
●
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.
●
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 return.
●
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.
●
Always watch carefully for swimmers during the engine operation.
●
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 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.
E
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-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.
1-7
E
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-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.
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.
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 rightof-way! Both of you should alter course to
Overtaking
If you are passing another vessel, you are
the “Give-Way” vessel. This means that the
1-8
E
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.
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
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 “fishing vessels” under the International Rules. Vessels
with trolling lines are not considered fishing
vessels. Fishing vessels have the right-ofway 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 letters and orange
boarders. They signify speed zones,
restricted areas, danger areas, and general
information.
1-9
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.
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 maximum rec-
ommended range (such as light boat loads),
reduce the throttle setting to maintain the
rpm in the proper operating range.

run. The lanyard 2 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 under power.
WARNING
@
Attach the lanyard to a secure place on
●
your clothing, your arm or leg while
operating.
Do not attach the lanyard to clothing
●
that could tear loose. Do not route the
lanyard in such a way that it could
become entangled, preventing it from
functioning.
Avoid accidentally pulling the lanyard
●
during normal operation. Loss of
engine 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.
