Mounting Height
Z150Q/Z175H
To run your boat at optimum efficiency,
the water-resistance (drag) of the boat
and outboard motor must be made as lit-
tle 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 causing the
engine to overheat. If the mounting-
height is too low, the water-resistance will
increase and thereby reduce engine effi-
ciency.
NOTE:
8 The optimum mounting height of the
outboard motor is affected by the
boat/motor combination. Test runs at
different heights can help determine the
optimum mounting height.
For further details, consult your Yama-
ha dealer or boat manufacture to deter-
mine the proper mounting height.
8 Refer to the section "TRIMMING OUT-
BOARD MOTOR" for instructions on
setting the trim angle of the outboard.
