Inspecting the jet thrust nozzle
angle
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.

Inspecting the shift cable
Place the shift lever in the reverse posi-
tion.
Make sure that the reverse gate makes
contact with the stopper 1 on the bracket,
and that 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.

nut 1 and turning the adjuster 2. Distance A and B: A = B
