Adjusting the carburetor  

The carburetor is a vital part of the engine

and requires very sophisticated adjustment.
Most adjusting should be left to a Yamaha
dealer who has the professional knowledge
and experience to perform it. However, the
operator may adjust the trolling speed as
part of the usual maintenance routine. 

CAUTION:

@ 

The carburetor was set at the Yamaha
factory after many tests. If the settings
are disturbed by someone who does not
have the necessary technical knowledge,
poor engine performance and damage
may result. 

@

EJU01303 

Adjusting the trolling speed  

1. Put the watercraft in the water. 
2. Start the engine and warm it up for 1 or 2

minutes. Using a diagnostic tachometer,
adjust the engine speed to specification. 

3. Turn the throttle stop screw 

1

 clockwise

to increase engine speed if necessary.
Turn it counterclockwise to decrease
engine speed if necessary. 

Trolling speed: 1,250–1,350 r/min
