BLEEDING THE OIL INJECTION
PUMP
1
1 Air bleeding screw
To bleed the oil injection pump, loosen
the air bleeding screw on the bleed
hose. Oil will flow into the oil injection
pump. Hold a rag under the screw hole
to catch oil as it spills out. Keep letting
oil run out until there are no bubbles in
the oil. Tighten the screw firmly and
wipe up any spilled oil completely.
Properly dispose of oil soaked rags.

CARBURETOR ADJUSTMENT

The carburetors are vital parts of the
engine and require very sophisticated
adjustment. Most adjusting should be
left to a Yamaha Boat dealer who has
the professional knowledge and experi-
ence to do so. However, the following
point may be serviced by the owner as
part of his usual maintenance routine.

The carburetor was set at the

the settings are disturbed without
having technical knowledge, poor
engine performance and damage
may result.
