2.1.1 Mounting height
The mounting height of the outboard motor greatly affects your boat running efficiency. If the mounting
height is too high, cavitation tends to occur, thus reducing the propulsion. If the mounting height is too low,
the water resistance will increase and thereby reduce engine efficiency. Mount the outboard motor so that
the anti-cavitation plate is between the bottom of the boat and a level 25mm below it.
NOTE:
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
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. Proper installation of the outboard includes
bolting the engine to the boat through the transom.
WARNING:
Loose clamp screws could allow the outboard motor to fall off or move on the transom. This
could cause loss of control.
