SAFETY

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.

INFORMATION

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 “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 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.

1-6

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 travelling 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.

side. This rule doesn’t apply if both of you will clear one another if you continue on your set course and speed.

102044

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.

102045

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)

102046

Overtaking

If you are passing another vessel, you are the “Give-Way” vessel. This means that

1-7

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.

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 “fishing 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 informa-

FUELING INSTRUCTIONS

GASOLINE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE! 8 Do not smoke when refueling, and

keep away from sparks, flames, or other sources of ignition.

8 Stop engine before refueling. 8 Refuel in a well-ventilated area. Refuel

portable fuel tanks off the boat.

8 Take care not to spill gasoline. If gaso-

line spills, wipe it up immediately with dry rags.

8 Do not overfill the fuel tank. 8 Tighten the filler cap securely after

refueling.

8 If you should swallow some gasoline

inhale a lot of gasoline vapor, or get gasoline in your eyes, get immediate medical attention.

8 If any gasoline spills onto your skin,

immediately wash with soap and water. Change clothing if gasoline spills on it.

8 Touch the fuel nozzle to the filler open-

ing or funnel to help prevent electrostatic sparks.

Use only new clean gasoline which has been stored in clean containers and is not contaminated with water or foreign matter.

1-10

EMU00018

GASOLINE (PETROL)

Recommended gasoline:

Regular unleaded gasoline with a minimum octane rating of 86 (Pump Octane Number) = (R+M)/2

If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel. If unleaded gasoline is not available, then leaded regular gasoline can be used.

EMU00027

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. Gasohol containing methanol is not recommended by Yamaha because it can cause fuel system damage or engine performance problems.

EMU00858

ENGINE OIL

Recommended engine oil: YAMALUBE 2 STROKE OUTBOARD OIL

If the recommended engine oil is not available, another 2-stroke engine oil with a NMMA-certified TC-W3 rating may be used.

1-11

EMU01430

BATTERY REQUIREMENT

Do not use a battery that does not meet the specified capacity. If a battery which differs from the specification is used, the electrical system may perform poorly or be overloaded, causing electrical system damage.

8 A battery cannot be connected to mod-

els which do not have a rectifier or rectifier regulator.

Models without a rectifier or rectifier

regulator: 25NMH, 30DMHO, 25JMH

8 If you wish to use a battery with the

above models, install an optional rectifier regulator.

Models with only a rectifier

installed: 30DEHO

8 Using a maintenance-free battery with

the above models can shorten the life of the battery significantly.

8 Use caution when connecting acces-

sories such as fish finders, as they may be damaged by high voltage. Install an optional rectifier regulator or use accessories rated to withstand 18 volts or higher with the above models. Consult your Yamaha dealer for details on installing an optional rectifier regulator.

Choose a battery for electric start models which meets the following specifications.

Minimum cold crank performance 210 Amps at -17.8°C (0°F) Minimum reserve capacity 40 minutes at 26.7°C (80°F)

1-12

EMU01395

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.

1-13

602016

10-3/4x17-F

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 recommended range (such as light boat loads), reduce the throttle setting to maintain the rpm in the proper operating range.

1 Propeller diameter (in inches) 2 Propeller pitch (in inches) 3 Type of propeller (propeller mark)

Refer to the section “CHECKING PROPELLER” for instructions on propeller removal and installation.

ENGINE STOP LANYARD SWITCH (for Tiller control model)

The lock-plate on the end of the lanyard 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.

1 Lock-plate 2 Lanyard

8 Attach the engine stop switch lanyard

to a secure place on your clothing, your

arm or leg while operating.

8 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.

8 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.
