Installation
5.
Mount the outboard motor on the center line
(keel line) of the boat, and ensure that the boat
itself is well balanced. Otherwise the boat will be
hard to steer. For boats without a keel or which are
asymmetrical, consult your dealer.
Steering friction adjuster
Mounting height
To run your boat at optimum efficiency, the
water resistance (drag) of the boat and out-
board motor must be made as little as possible.
The mounting height of the outboard motor greatly
affects the water resistance. If the mounting
height is too high, cavitation tends to occur,
thus reducing the propulsion; and if the propeller
tips cut the air, the engine speed will rise
abnormally and cause the engine to overheat. 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 25 mm (1 in) below it.

Turn the steering friction adjuster coun-
terclockwise to set the steering friction according
to operator preference.
WARNING! If there is too
much resistance it could be difficult to steer,
which could result in an accident.
