Checking the outboard motor
mounting height
1. Check that the anti-cavitation plate is
aligned with the bottom of the boat. If the
mounting height is too high, cavitation
will occur and propulsion will be reduced.
Also, the engine speed will increase
abnormally and cause the engine to
overheat. If the mounting height is too
low, water resistance will increase and
reduce engine efficiency.
NOTE:
The optimum mounting height is affected by
the combination of the boat and the outboard
motor. To determine the optimum mounting
height, test run the outboard motor at differ-
ent heights.
2. Check that the clamp brackets are
secured with the clamp bolts.
Checking the remote control cables
1. Set the remote control lever or shift lever
to the neutral position and fully close the
throttle lever or throttle grip.
