starboard. This pulling condition can be corrected by using a pliers
and bending the ends of the exhaust fins 1.5 mm (1/16 in.) toward
the starboard side of the outboard.

Worn/Dull Impeller

The intake of gravel through the pump can round off and wear the
leading edges of the impeller. Some conditions that could be
experienced from a worn/dull impeller are as follows:
• Noticeable performance loss, especially on acceleration
• Difficulty getting the boat on plane
• An increase in engine RPM at wide open throttle
IMPORTANT: Do not sharpen or alter the top side lifting angle.
