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.
