Instructions on servicing outboard engines ” Suzuki , Mercury , Yamaha , Johnson , Evinrude, and Honda  “


    • 1

      Remove the engine cowling from the top of the outboard motor. Under the cowling you will have easy access to the spark plugs and carburetor.

    • 2

      Disconnect the wires from the spark plugs. The number of spark plugs will depend on the size of your outboard motor. Remove the spark plug from the motor using a spark plug wrench. Inspect the bottom of the spark plug and clean off the black carbon residue with a wire brush. If the carbon is excessive, replace the old spark plug with a new one. Replace the spark plug and reconnect the spark plug wire.

    • 3

      Locate the carburetor, which is typically near the top of the outboard engine. Use a small screwdriver to remove the fuel reservoir from the carburetor. Spray carburetor cleaner through the passages inside the carburetor. Replace the fuel reservoir.

    • 4

      Use a screwdriver or Allen key to remove the lower end of your outboard motor. Inspect and remove the water pump impeller from its casing. Look for scoring or damage to the blades. If the impeller has extensive damage it may need to be replaced or serviced by a mechanic. Inspect the oil and look for signs of water leakage. If the oil has milky appearance, you may need to replace the seals. The number and location of these seals will vary from engine to engine. Refer to your owner’s manual for your engine if the seals need to be replaced.
