JET PUMP CLEAN-OUT
PROCEDURE
WARNING
SEVERE INJURY OR DEATH MAY
RESULT IF YOU IGNORE ANY OF
THE FOLLOWING:
● Turn off and remove both ignition
keys, remove lanyard, and wait
for all movement to stop before
removing access port caps.
● Never override interlocks to run
engine with hatch open.
● The impeller has sharp edges. Be
careful when reaching into jet
pump area.
If weeds or debris get caught in the
intake or impeller, cavitation can occur,
and though the engine speed rises, for-
ward thrust will decrease. If this condi-
tion is allowed to continue, pump dam-
age can occur and the engines may
overheat and seize. If there is any sign
that the jet intake or impeller is clogged
with weeds or debris, follow this
cleanout procedure.
1. Turn off and remove ignition keys,
remove lanyard, and wait for all
movement to stop.
2. Lift the hatch on the rear platform.
