Yamaha EXCITER Owner's/operator's Manual - Bleeding The Oil Injection
BLEEDING THE OIL INJECTION
PUMP
➀
Air bleeding screw
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.
___________
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.
Trolling Speed ( Idle)
➀
Throttle stop screw
NOTE:
_________________
A diagnostic tachometer is useful for
this procedure.
Place the Jet Boat afloat. Start the
engine and warm it up for one or two
minutes.
Using a diagnostic tachometer, adjust
the engine’s speed to specification.
Turn the throttle stop screw clockwise
to increase engine speed or counter-
clockwise to decrease engine speed.
Trolling speed: 1,200~1,300 r.p.m.
