Cleaning the jet intake and impeller

If weeds or debris get caught in the jet 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. Al-
ways stop the engine before beaching the wa-
tercraft.

WARNING
Before attempting to remove weeds or de-
bris from the jet intake or impeller area,
shut the engine off and remove the clip
from the engine shut-off switch. Severe in-
jury or death could result from coming in
91
contact with the rotating parts of the jet
pump.

CAUTION:
If weeds or debris get caught in the jet in-
take, do not operate the watercraft above
trolling speed until they have been re-
moved.
(1) Turn the watercraft on its side as shown.
