PUMP PRESSURIZATION

Whenever doing any type of repair on jet pump, a
pressure test should be done to check for leakage.
Proceed as follows:
– Remove drain plug from cover.
– Apply Loctite PST 592 on threads of fitting tool
(P/N 295 000 086) then secure on cover.
– Connect pump gauge tester (P/N 295 000 085)
to fitting.
– Pressurize pump to a maximum of 70 kPa (10
PSI).

– Pump must maintain this pressure for at least
10 minutes.
CAUTION: Repair any leak, failure to correct a
leak will lead to premature wear of pump com-
ponents.
NOTE: If there is a pressure drop spray soapy wa-
ter around cover. If there are no bubbles, impeller
shaft, impeller shaft seal, or jet pump housing is
leaking through porosity and has to be replaced.
Jet pump unit has to be disassembled. If jet pump
has been overhauled, the impeller shaft seal
no. 19 may be leaking; Add a small quantity of
SEA-DOO JET PUMP SYNTHETIC OIL to wet the
oil seal. Let soak and recheck.
– Disconnect pump gauge tester and remove fit-
ting.
– Check oil level. Refill as necessary.
– Apply Loctite PST 592 to threads of filler plug
then secure it in cover.

INSTALLATION

Jet Pump Housing
Generously apply synthetic grease on drive shaft
splines.
Make sure rubber damper is on drive shaft end.
Install jet pump. If necessary, wiggle jet pump to
engage drive shaft splines in impeller.
