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
General information
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.
Incorrect propeller selection and incorrect
●
use may not only cause engine damage,
but also adversely affect fuel consumption.
Consult your dealer for correct 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 nonswimmers should always wear PFDs, and
everyone should wear PFDs when there
are potentially hazardous boating conditions.
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 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 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 accidentally leave the helm, the cord will pull from
3
General information
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 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 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.
●
Do not illegally discard empty containers
used to replace or replenish oil. For the
correct processing of empty containers,
consult the dealer where you purchased
the oil.
●
When replacing oils used to lubricate the
product (engine or gear oil), be sure to
wipe away any spilt oil. Never pour oil without using a funnel or similar device. If necessary, verify the necessary replacement
procedure with the dealer.
●
Never illegally discard (dump) the product.
Yamaha recommends consulting the deal-
er on discarding the product.

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.
5
General information
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.
EMU25510
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.
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 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 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.
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:
sel head-on)
Crossing:
er vessel’s path)
Overtaking:
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 GiveWay 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-
(you are approaching another ves-
(you are traveling across the oth-
(you are passing or being
6
General information
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 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.
EMU25530
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 power-driven vessel has the right-of-way.
2. Sailing vessels should keep clear of any
fishing vessel.
7
General information
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.
Remember, markings may vary by geographic location. Always consult local boating authorities before driving your boat in
unfamiliar waters.

●
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 electrostatic sparks.
ECM00010
CAUTION:
Use only new clean gasoline which has
been stored in clean containers and is not
contaminated with water or foreign matter.
EMU25570
Gasoline
If knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
Recommended gasoline:
Regular unleaded gasoline with a minimum octane rating of 86 (Pump Octane Number) = (R+M)/2
EMU25660
Engine oil
Use Yamalube 2-M outboard oil. If Yamalube 2-M is not available, use only another outboard motor manufacturer’s factorybrand oil with TC-W3 rating.
Recommended engine oil:
YAMALUBE 2 STROKE OUTBOARD
OIL
ECM01290
CAUTION:
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
ECM01060
CAUTION:
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.
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing methanol. 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.
10
For electric start models, choose a battery
which meets the following specifications.
EMU25711
Battery specifications
Minimum cold cranking amps (CCA/
SAE):
512.0 A
Minimum marine cranking amps (MCA/
ABYC):
675.0 A
Minimum reserve capacity (RC/SAE):
182 minutes
NOTE:
The engine cannot be started if battery voltage is too low.
EMU25742
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:
Select a propeller which will allow the engine
to reach the middle or upper half of the operating 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 installation, see page 60.

To increase resistance, turn the adjuster
clockwise. To decrease resistance, turn the
adjuster counterclockwise.
EWM00031
WARNING
Do not overtighten the friction adjuster. If
there is too much resistance, it could be
difficult to move the remote control lever
or throttle grip, which could result in an
accident.
When constant speed is desired, tighten the
adjuster to maintain the desired throttle setting.

Engine stop lanyard switch
The lock plate must be attached to the engine 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 under power.
EWM00120
WARNING
●
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 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.
NOTE:
The engine cannot be started with the lock
plate removed.
