CLEANING THE JET INTAKE AND
IMPELLER
If weeds or debris get caught in the intake
or impeller, cavitation can occur, and
though the engine speed rises, forward
thrust will decrease. If this condition is
allowed to continue, the engine will over-
heat and may seize. If there is any sign
that the jet intake or impeller is clogged
with weeds or debris, beach the vehicle
and check the intake and impeller. Always
stop the engine before beaching the vehi-
cle.
w
Before attempting to remove weeds or
debris from the jet intake or impeller
areas, shut off the engine and remove the
lock plate from the engine stop lanyard
switch. Severe injury or death could
result from coming in contact with the
rotating parts of the jet pump.
1) Turn the vehicle on its side as shown.
cC
Place a suitable clean cloth or carpeting
underneath the vehicle to protect it from
abrasions and scratches, and always turn
the vehicle over on its port (left) sides.
When turning the vehicle on its side, sup-
port the front portion so the handlebars
cannot be bent or damaged.
