BLEEDING THE OIL INJECTION
PUMP
If the oil tank becomes completely
empty or any hose connected to oil
pump has been disconnected, the oil
pump must be bled to ensure proper oil
flow.
If bleeding of the oil pump is necessary,
take the Jet Boat to your nearest
Yamaha dealer.

CARBURETOR ADJUSTMENT

The carburetors are vital parts of the
engine and require very sophisticated
adjustment. Most adjusting should be
left to a Yamaha Jet Boat dealer who
has the professional knowledge and
experience to do so. However, the fol-
lowing point may be serviced by the
owner as part of his usual maintenance
routine.
___________
CAUTION:
The carburetor was set at the
Yamaha factory after many tests. If
the settings are disturbed without
having technical knowledge, poor
engine performance and damage
may result.
