Always match the engine to the recommendations as established by the boat manufacturer. Every new boat will have a manufacturers power recommendation, the maximum rated power is usually stamped on the manufacturers plate on the hull. Do not exceed this stated maximum horsepower.

Matching the correct shaft length for your outboard is crucial. Click here for further details.

Install the outboard at the stern on the centre line of the transom. See the diagram below. Ensure that the boat is well balanced.

As a general rule the outboard should be installed so the anti-cavitation plate is parallel to the bottom of the boat. The water level must be at least 100mm (3.9 inches) above the anti-cavitation plate with the motor not running, otherwise the water pump may not receive sufficient cooling water, and the engine will overheat. If the height is too low, the idle port could go underwater, causing engine damage or hard starting.

Motor Attachment

1. Attach the stern bracket to the transom and tighten the clamp screws.
    
2. If the outboard requires bolts follow the diagram below. Apply a silicon sealant (three bond 1216 or equivalent) to the outboard motor mounting holes.
    
3. Set the outboard on the boat and secure with the bolts, washers and lock nuts.
