Operation
motor greatly affects the water resistance. If
the mounting height is too high, cavitation
tends to occur, thus reducing the propulsion
and causing the engine to overheat. If the
mounting height is too low, the water resis-
tance will increase and thereby reduce en-
gine efficiency. Mount the outboard motor so
that the anti-cavitation plate is about 130 mm
could result in reduced engine life or
even severe engine damage.
Do not use premixed fuel in this engine
because it could cause carbon depos-
its on the fuel injector and engine trou-
ble.

q
The optimum mounting height of the out-
board motor is affected by the boat and
motor combination and the desired use.
Test runs at different heights can help de-
termine the optimum mounting height.
Consult your Yamaha dealer or boat man-
ufacturer for further information on deter-
mining the proper mounting height.

Breaking in engine
Your new engine requires a period of break-
in to allow mating surfaces of moving parts to
wear in evenly. Correct break-in will help en-
sure proper performance and longer engine
