Jet pump clean-out procedure

WARNING
Severe injury or death may result if you ig-
nore any of the following:
Turn off and remove the main switch

key, remove the clip from the engine
shut-off switch, and wait for all move-
ment to stop before removing the ac-
cess port cap.
Never override the interlock to run the

engine with the rear platform hatch
open.
The impeller has sharp edges. Be care-

ful 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, forward thrust will de-
crease. If this condition is allowed to contin-
ue, jet pump damage can occur and the
engine may overheat and seize. If there is any
sign that a jet intake or impeller is clogged
with weeds or debris, follow this clean-out
procedure.
(1) Turn off and remove the main switch key,
remove the clip from the engine shut-off
switch, and wait for all movement to
stop.
(2) Open the rear platform hatch. (See page
65.)
(3) Check that the retaining cord is securely
attached to the access port cap and
strap eye.
