  • 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. 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

    Improper mounting of the outboard motor could result in hazardous conditions. For permanently  mounted models, your dealer or other person experienced in proper rigging should mount the motor. If you are mounting the motor yourself, you should be trained by an experienced person. For portable models, your dealer or other person experienced in proper outboard motor mounting should show you how to mount your motor.

  • Page 16: Clamping The Outboard Motor

    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. 2.1.2 Clamping the outboard motor Tighten the transom clamp screw evenly and securely.

  • Page 17: Breaking In Engine

    Attach to a secure mounting point on the boat to avoid the engine being completely lost if it accidentally falls off the transom. 3. Secure the clamp bracket to the transom using the appropriate bolts. For details, consult your PARSUN dealer.
