Inspecting the steering cable
Check for smooth operation of the handle-
bars and jet thrust nozzle.
Turn the handlebars as far as possible to
the right and left and check that the distance
between the jet thrust nozzle and the
bracket of the reverse gate are equal on
right and left sides.
If steering is stiff or misadjusted, have a
Yamaha dealer service it.
EJU00549a
Inspecting the shift cable
Place the shift lever in the reverse posi-
tion.
Make sure the gate makes contact with the
stopper 1 on the bracket, and the arm 2
makes contact with the reverse gate.
If the reverse gate does not reach the cor-
rect positions, have a Yamaha dealer ser-
vice it.

Inspecting and adjusting the
throttle cable

to the set position smoothly and that free
play is within specification.
1. Squeeze and release the throttle lever. If
the lever does not return smoothly, have
a Yamaha dealer service it.
2. Adjust free play a by loosening the lock-
nut 1 and turning the adjuster 2. Distance A and B: A=B
