Maintenance

1. Inspect the engine and engine mounts for damage or
wear. Replace, clean or repair as needed.
2. Inspect the condition of the spark plug and wire.
Replace as needed.

Clutch

The centrifugal clutch automatically engages when the
engine rpm is increased. Be sure that the idle speed
adjustment is set low enough so that the propeller does
not rotate at idle. Periodically disassemble the clutch and
clean debris from the clutch shoes and the inner clutch
bell.

Water Cooling System

If water does not stream out of the water outlets while
the boat is moving forward, immediately stop the engine
and clean obstruction from the water cooling system. The
engine and muffler have separate circulation connections.
1. Disassemble and clean the water cooling system to
remove blockage and prevent overheating.
2. Replace damaged parts.
