     Safety information 
     
    Before mounting or operating the outboard
    motor, read this entire manual. Reading itshould 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
    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 tak-
    ing drugs. About 50% of all boating fatali-
    ties involve intoxication. 
     
    Have an approved personal flotation de-
    vice (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 condi-
    tions. 
     
    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 be-
    fore starting the engine. 
     
    This product emits exhaust gases which
    contain carbon monoxide, a colorless,

    clude nausea, dizziness, and drowsiness.
    Keep cockpit and cabin areas well ventilat-
    ed. 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 acciden-
    tally leave the helm, the cord will pull from
    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 4. 
     
    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 re-
    turn. 
     
    Use common sense and good judgment
    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 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 towipe away any spilt oil. Never pour oil with-
    out using a funnel or similar device. If nec-
    essary, 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 agen-
    cies. 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 pro-
    vided for your convenience only. Consult
    your local U.S. Coast Guard Auxiliary or De-
    partment 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-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” 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-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 brief-
    ly 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 naviga-
    tion 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 ex-
    cept when a collision will occur unless both
    vessels try to avoid each other. If that is the
    case, both vessels become “Give-Way” ves-
    sels. 
    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: 
     (you are approaching another ves-✩✦✯✬✤✲✲✣ ✧

    sel head-on) 
    Crossing: 
     (you are traveling across the oth-
    er 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 shad-
    ed area must yield to you (they are the Give-
    Way 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-
    way! Both of you should alter course to avoid
    an accident. You should keep the other ves-
    sel 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 oth-
    er 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 direc-
    tion, 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 an-
    other 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 oth-
    er 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✩✦✯✬✤✲✲✣
