    Engine fails to operate 
    EMU29704 
    Cold engine fails to start 
    If the engine fails to start when it is cold, use
    the following procedure.
    WARNING
     
    EWM00410  
    When starting or operating the engine, do
    not touch the ignition coil, spark plug
    wire, spark plug cap, or other electrical
    parts carrying high voltage. Keep loose
    clothing and other objects away from the
    engine when starting it. Do not touch the
    flywheel or other moving parts when the 
    engine is running. 
    1. Adjust the trim angle so that the drive
    shaft is at right angles to the water sur-
    face or is trimmed in.
    2. On models equipped with an emergency
    starter valve, open it. The valve is locat-
    ed behind the silencer cover on the front
    of the engine.
    3. Squeeze the primer pump two or three
    times to feed fuel.4. Open the throttle slightly without shifting
    using the throttle grip, neutral throttle le-
    ver or free accelerator. It is necessary to
    change the throttle opening slightly de-
    pending on the engine temperature. Af-
    ter the engine starts, return the throttle to
    its original position.
    5. Turn the main switch to “” (on).

    6. Turn the main switch to “” (start).
    CAUTION:
     
    ECM00191  
     
    Never turn the main switch to “”
    (start) while the engine is running. 
     
    Do not keep the starter motor turning
    for more than 5 seconds. If the starter
    motor is turned continuously for more
    than 5 seconds, the battery will be
    quickly discharged, thus making it im-
    possible to start the engine. The starter
    can also be damaged. If the engine will
    not start after 5 seconds of cranking,
    return the main switch to “” (on), wait
    10 seconds, then crank the engine 
    again. 
    7. After the engine starts, close the emer-
    gency starter valve (if used), then return
    the throttle to its original position.
    NOTE:
     
    When the starter mechanism malfunctions, 
    see page 64. 
    EMU29760 
    Treatment of submerged motor 
    If the outboard motor is submerged, immedi-
    ately take it to a Yamaha dealer. Otherwise
    some corrosion may begin almost immedi-
    ately.

    motor to a Yamaha dealer, follow the proce-
    dure below in order to minimize engine dam-
    age. 
    EMU29771

    weed, and so on, with fresh water.
    2. Remove the spark plugs and face the
    spark plug holes downward to allow any
    water, mud, or contaminants to drain.
