    Spark Plug Service 
    RECOMMENDED SPARK PLUGS: 
    CRSEH-9 (NGK) 
    U I6FER9 (DENSO) 
    t 1 Incorrect spark plugs can cause engine 
    damage. 
    Unlatch and remove the engine cover 
    (P.55). 
    Disconnect the spark plug caps from 
    the spark plugs. 
    Remove the spark plugs with a spark 
    plug wrench and screwdriver 
    supplied in the tool kit. 4. Inspect the spark plugs. Replace 
    them if the electrodes are worn, or if 
    the insulators arc cracked or chipped. 
    Clean the spark plugs with a wire 
    brush if you are going to reuse them. 5. 0.8 - 0.90 mm 
    (0.031 - 0.035 in) 
    Measure the spark plug electrode gap 
    with a suitable gauge. The gap 
    should be 0.03 1 - 0.035 inches (0.80 - 
    0.90 mm).

    6. Install the spark plugs carefully, by 
    hand, to avoid cross-threading. 7. 
    8. 
    9. After each spark plug seats, tighten 
    with a spark plug wrench supplied in 
    the tool kit to compress the sealing 
    washer. 
    If reinstalling the used spark plugs, 
    tighten l/8 - l/4 turn after the spark 
    plugs seat. 
    If reinstalling new spark plugs, 
    tighten l/2 turn after the spark plugs 
    seat. 
    Loose spark plugs can over heat and 
    damage the engine. Overtightening 
    the spark plugs can damage the 
    threads in the cylinder head. 
    Attach the spark plug caps. 
    Install and lock the engine cover.

    REFUELING 
    Portable Fuel Tank 
    (optional equipment) 
    FUEL TANK CAPACITY: 
    3.2 US gal ( 12.0 t ) 
    Check the fuel gauge and refill the tank 
    when necessary. 
    Remove the fuel tank from the boat for 
    refueling.

    To refuel, turn the vent knob 
    counterclockwise to the OPEN position, 
    and unscrew the fuel tank cap 
    FUELGAUGE 
    Refuel in a well-ventilated area. Fill the 
    tank to the SAFE FILL LEVEL lint. 
    After refueling, install the cap and tighten 
    it securely. Turn the vent knob clockwise 
    to the CLOSED position, and rctum the 
    fuel tank to the boat. Gasoline is highly flammable and 
    explosive. 
    You can be burned or seriously 
    injured when handling fuel. 
    l Stop the engine and keep heat, 
    sparks, and flame away. 
    l Handle fuel only outdoors. 
    l Wipe up spills immediately. 
    Never refill the fuel tank inside a building 
    where gasoline fumes may reach flames 
    or sparks. Keep gasoline away from 
    appliance pilot lights, barbecues, electric 
    appliances. power tools, etc. 
    Spilled fuel is not only a fire hazard, it 
    causes environmental damage. Wipe up 
    spills immediately.  
    						
    							SERVICING YOUR HONDA OUTBOARD MOTOR 
    FUEL RECOMMENDATIONS 
    Use unleaded gasoline with a pump 
    octane rating of 86 or higher. 
    These outboard motors are certified to 
    operate on unleaded gasoline. Unleaded 
    gasoline produces fewer engine and spark 
    plug deposits and extends exhaust system 
    life. 
    Never use stale or contaminated gasoline 
    or an oil/gasoline mixture. Avoid getting 
    dirt or water in the fuel tank. 
    Occasionally you may hear a light “spark 
    knock” or “pinging” (metallic rapping 
    noise) while operating under heavy loads. 
    This is no cause for concern. 
    If spark knock or pinging occurs at a 
    steady engine speed, under normal load, 
    change brands of gasoline. If spark knock 
    or pinging persists, see an authorized 
    Honda marine dealer. piq 
    Running the engine with persistent spark 
    knock or pinging can cause engine 
    damage. 
    Running the engine with persistent spark 
    knock or pinging is misuse, and the 
    Distributor ? Limited Warranty does not 
    cover parts damaged by misuse. 
    Fuel Pump Filter Inspection 
    and Replacement 
    The fuel pump filter is located under the 
    engine cover, on the right side of the 
    engine. 
    Water or sediment accumulated in the 
    filter can cause loss of power or hard 
    starting. To prevent engine malfunction, 
    inspect the filter and replace when 
    necessary. Gasoline is highly flammable and 
    explosive. 
    You can be burned or seriously 
    injured when handling fuel. 
    l Stop the engine and keep heat, 
    sparks, and flame away. 
    l Handle fuel only outdoors. 
    l Wipe up spills immediately.

    sediment accumulation. 
    If the filter is OK, reinstall it. If 
    water and/or sediment are prcscnt, 
    replace the filter as dcscribcd in the 
    following steps. Always replace the 
    filter at the scheduled replacement 
    interval (p.54). 3. Disconnect the fuel hose from the 
    outboard motor, and place clamps on 
    the fuel hoses on each side of the 
    filter to prevent fuel leakage when 
    the fuel hoses are disconnected.

    4. Remove the fuel tubes from the used 
    filter, and discard the filter. 
    To ease tube removal, rcleasc the 
    tube clips by squeezing the clip ends 
    together with pliers while pulling off 
    the tubes.

    . . ARROW 
    (Fuel Flow Direction) 
    Install the new filter on the fuel 
    hoses, with the fuel flow arrow 
    pointing toward the fuel pump as 
    shown. Fuel flow will be impeded if 
    the filter is installed backward. 
    Remove the fuel tube clamps, and 
    connect the fuel hose to the outboard 
    motor. Check for leaks. 
    Install and lock the engine cover. 
    Portable Fuel Tank and Filter 
    Cleaning 
    Fuel Tank 
    Empty the portable fuel tank into an 
    approved gasoline container. Use a 
    funnel to avoid spilling fuel. Rinse the 
    fuel tank with nonflammable solvent to 
    remove any accumulated sediment.

    turning it counterclockwise, then 
    remove the fuel hose connector and 
    fuel filter from the tank. 
    Clean the filter in nonflammable 
    solvent. Inspect the fuel tank filter 
    and the connector O-ring. Replace 
    them if damaged. 
    Reinstall the filter and hose 
    connector in the fuel tank. Tighten

    Recoil Starter Rope Inspection 
     
    RECOIL STARTER ROPE 
    Inspect the recoil starter rope, and replace 
    it if it becomes frayed. 
    Always keep the emergency starter rope 
    on the boat in cast the recoil starter rope 
    fails. Anoed Replacement 
    The anodes are located on each side of the 
    gearcase. They are made of a sacrificial 
    material that helps to protect the outboard 
    motor from corrosion. 
    Replace the anodes when they have been 
    reduced to about half their original size, 
    or if they are crumbling. 
    lNoTlCEl I I 
    Painting or coating the anodes will defeat 
    their purpose and will lead to rust and 
    corrosion damuge to the outboard motor. 
    The anodes must be exposed to the water 
    in order to protect the outboard motor:
