    Lif ting the outboard motor by the
    engine cover, or using the
    installed outboard motor as a
    handle or lever to move the boat,
    can damage the outboard motor. If there is insuf f icient road clearance
    in the normal running position, then
    tilt the outboard motor and use a
    motor support bar, or remove the
    outboard motor from the boat. Refer

    							65 OIL PRESSURE INDICATOR
    LIGHT GOES OFF AND
    ENGINE SPEED IS LIMITED
    TAKING CARE OF UNEXPECTED PROBLEMS
    OIL PRESSURE INDICATOR LIGHT
    If the throttle is closed suddenly af ter
    f ull throttle operation, engine speed
    may drop below the specif ied idle
    rpm, and that could activate the
    engine protection system
    momentarily.
    If low oil pressure activates the
    engine protection system, stop the
    engine, check the engine oil level
    (p. ), and add oil if needed.
    If the engine protection system
    remains activated after 30 seconds,
    return to the nearest boat landing,
    and have the outboard motor
    inspected by an authorized Honda
    marine dealer. With the engine oil at the
    recommended level, restart the
    engine. If the lubrication system is
    OK, the green indicator light should
    come on within 30 seconds, and the
    engine will respond normally to
    throttle grip operation. If oil pressure becomes low, the
    green indicator light will go off. If
    you are at cruising speed, engine
    speed will decrease gradually.
    Low oil pressure may be the result of
    a low engine oil level, or there may
    be a problem with the engine
    lubrication system.

    							66 SUBMERGED MOTOR
    TAKING CARE OF UNEXPECTED PROBLEMS
    A submerged outboard motor must
    be serviced immediately af ter it is
    recovered f rom the water in order to
    minimize corrosion.
    Remove the engine cover, and
    rinse the outboard motor with
    f resh water to remove salt water,
    sand, mud, etc.
    Drain the carburetor as described
    on p. .Change the engine oil as described
    on p. . If there was water in the
    engine crankcase, or if the used
    engine oil showed signs of water
    contamination, then a second
    engine oil change should be
    performed after running the engine
    for half an hour.
    If the engine was running when it
    submerged, there may be
    mechanical damage, such as a bent
    connecting rod. If the engine binds
    when cranked, do not attempt to
    run the engine until it has been
    repaired. If there is a Honda marine dealer
    nearby, take the motor to the dealer
    immediately. If you are f ar f rom a
    dealer, proceed as f ollows:
    Remove the spark plug (p. ),
    and remove the clip f rom the
    engine stop switch. Pull the recoil
    starter grip, rotate the f lywheel a
    f ew revolutions to completely
    expel any water from the cylinder. 1.

    TAKING CARE OF UNEXPECTED PROBLEMS
    When cranking the engine with
    an open ignition circuit (spark
    plug removed f rom the ignition
    circuit), remove the clip f rom
    the engine stop switch to
    prevent possible damage to the
    ignition system.Attempt to start the engine.
    If the engine starts, and no
    mechanical damage is evident,
    continue to run the engine for a
    half hour or longer. Be sure the
    water level is at least two inches
    above the antiventilation plate to
    avoid overheating and water pump
    damage. Pour a teaspoon of engine oil into
    the spark plug hole, then pull the
    recoil starter grip several times to
    lubricate the inside of the cylinder.
    Reinstall the spark plug, and put
    the emergency stop switch clip
    into the switch.If the engine f ails to start, remove
    the spark plug, clean and dry it,
    then reinstall the spark plug and
    attempt to start the engine again.
    As soon as possible, take the
    outboard motor to an authorized
    Honda marine dealer for
    inspection and service. 5.
