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 hull
are equal on right and left sides.
If steering is stiff or misadjusted, have a
Yamaha dealer service it.Distance A and B: A = B

●Steering cable ball joint (handlebar end)
●Steering cable inner wire (handlebar end)
1. To access the steering cable and joint,
remove the handle cover by removing
the two bolts.
2. Grease the steering cable ball joints both
on the handlebar end of the cable and on
the jet thrust nozzle end.
3. Extend the steering cable inner wire, and
then apply a thin coat of grease to both
the handlebar end and the jet thrust noz-
zle end.
●Steering cable ball joint (nozzle end)
●Steering cable inner wire (nozzle end)
●Steering handle pivot shaft
Lubrication of the steering handle pivot
shaft requires disassembly of steering com-
ponents. Have a Yamaha dealer lubricate it.

Emergency procedures
Cleaning the jet intake and
impeller
If weeds or debris get caught in the intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine
speed rises. If this condition is allowed to
continue, the engine will overheat and may
seize. If there is any sign that the jet intake
or impeller is clogged with weeds or debris,
beach the watercraft and check the intake
and impeller. Always stop the engine before
beaching the watercraft.
WARNING@Before attempting to remove weeds or
debris from the jet intake or impeller
areas, shut the engine off and remove
the clip from the engine shut-off switch.
Severe injury or death could result from
coming in contact with the rotating parts
of the jet pump.
@
1. Turn the watercraft on its side as shown.
CAUTION:@●Place a suitable clean cloth or carpet-
ing underneath the watercraft to pro-
tect it from abrasions and scratches.
●Always turn the watercraft over onto
its port (left) side.
●When turning the watercraft on its
side, support the bow and secure the
steering pole, otherwise the steering
pole and handlebars could be bent or
damaged.
@
2. Remove any weeds or debris from
around the drive shaft, impeller, and jet
thrust nozzle.
If debris is difficult to remove, consult
your Yamaha dealer.

Submerged watercraft
If the watercraft is submerged or flooded
with water, follow the procedure below and
consult a Yamaha dealer as soon as possi-
ble. Failure to do so may result in serious
engine damage!
1. Beach the watercraft and remove the
hood. Turn the watercraft over far
enough to drain the water from the
engine compartment. Make sure all
water is thoroughly drained.
CAUTION:@Turning the watercraft on its side with the
hood removed could cause damage to
the steering pole. Use two people to pro-
vide enough support to make sure that
the steering pole is not damaged.
@
2. Turn the watercraft upright again.
3. Turn the fuel cock knob to “OFF.”
4. Remove the spark plugs and dry them
with a cloth.
5. Without reinstalling the spark plugs,
crank the engine until all water in the cyl-
inders has been drained.
6. Install the spark plugs.
7. Turn the fuel cock knob to “ON.”
8. Launch the watercraft into the water, and
then run the engine for at least
10 minutes. If engine will not start,
repeat steps above.
9. Turn the engine off. Turn the fuel cock
knob to “OFF.”
10. Remove the silencer cap and spray a
rust inhibitor into the carburetor while
cranking the engine.
11. Have the watercraft inspected by a
Yamaha Dealer as soon as possible.
