    Refuel in a well-ventilated area; refuel portable fuel tanks off the boat. Do not overfill the fuel tank. Take care not to spill gasoline, if gasoline spills, wipe it up immediately. Tighten the filler cap securely after refueling. If you should swallow some gasoline, inhale gasoline vapor, or get gasoline in your eye, get immediate medical attention.
  • Page 13 PARSUN dealers stock a range of propellers and can advise you and install a propeller on your outboard that is best suited to your application.

  • Page 14: Operation

    2 Operation 2.1 Installation Mount the outboard motor on the center line (keel line) of the boat. For boats without a keel or which are asymmetrical, consult your dealer. 1. center line (keel line) NOTE: During water testing check the buoyancy of the boat, at rest, with its maximum load. Check that the static water level on the exhaust housing is low enough to prevent water entry into the power head, when water rises due to waves when the outboard is not running.

  • Page 15: Mounting Height

    The optimum mounting height of the outboard motor is affected by the boat and motor combination and the desired use. Test runs at a different height can help determine the optimum mounting height. For further information, consult your PARSUN dealer or boat manufacturer.

  • Page 16: Clamping The Outboard Motor

    2.1.2 Clamping the outboard motor 1. Tighten the transom clamp screw evenly and securely. Occasionally check the clamp screws for tightness during operation of the outboard motor because they could become loose due to engine vibration. CAUTION: Outboards that use clamp bracket screws alone are INSUFFICIENT to properly and safely secure the outboard to the Transom.

  • Page 17: Breaking In Engine

    3. Secure the clamp bracket to the transom using the appropriate bolts. For details, consult your PARSUN dealer. WARNING Avoid using bolts, nuts or washers inappropriate. After tightening, test run the engine and check their tightness. 2.2 Breaking in engine Your new engine requires a period of breaking to allow mating surfaces of moving parts to wear in evenly.

  • Page 18: Pre-Operation Checks

    2.3 Pre-operation checks Fuel Check to be sure you have plenty of fuel for your trip. Make sure there are no fuel leaks or gasoline fumes. Check fuel line connections to be sure they are tight Be sure the fuel tank is positioned on a secure, flat surface, and that the fuel line is not twisted or flattened, or likely to contact sharp objects.
