Propeller Trim Angle
You may adjust the propeller strut to add up
or down trim to the propeller by loosening
the propeller strut bolt and sliding the
propeller strut up to increase top-end speed
(but steering response will decrease and
cavitation may occur if excessively adjusted).
Lowering the trim angle will increase handling
performance (but may cause the boat to over-
steer and decrease speed).
Water-Cooled Cylinder Head and
Muffler Cooling
The exhaust system is cooled after the
cylinder head. See photo for proper cooling
line routing. Do not alter the cooling line
routing method.
