SAFETY
Q
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 “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 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
102045
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.
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.
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
102046
Overtaking
If you are passing another vessel, you are the “Give-Way” vessel. This means that the other vessel is expected to maintain
1-8
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 “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-

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.

E
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.
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.

Engine Stop Lanyard Switch
The lock-plate 1 must be attached to the engine stop lanyard switch for the engine to 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.

8 Attach the 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.
NOTE:
The engine cannot be started with the lock-plate removed.
