Checking the outboard motor mount-
ing height
1. Check:
• Outboard motor mounting height
Improper Adju
st.
a. Check that the anti-cavitation plate “1”
is aligned with the
bottom of the boat
“2”. If the mounting height is too high,
cavitation will occur and propulsion will
decrease. Besides, the engine speed
will increase abnormally and cause
the engine to overheat. If the mounting
height is too low, water resistance will
increase, which will decrease engine
efficiency and performance.
The appropriate mounting height depends on
the combination of the boat and outboard mo
-
tor. To determine the appropriate mounting
height, test run the
outboard motor at different
heights.
2. Check:
• Mount bolt
