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,
return to shore 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
area, 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.
@
CAUTION:@ If weeds or debris get caught in the
intake, do not operate the watercraft
above trolling speed until they have been
removed.
@
1. Turn the watercraft on its side as shown.
