If the engine oil pressure is out of specifications,
check the points described in TROUBLESHOOT-
ING section.
Reinstall plug.
NOTE: Depending the oil pressure switch, the
threshold value to send a signal of low oil pressure
may vary from a minimum of 180 kPa (26 PSI) to
a maximum of 220 kPa (32 PSI).
Oil Change
Oil Draining
NOTE: If water is found in oil (oil will be milky), re-
fer to submerged engine in MAINTENANCE sec-
tion and follow the procedure to flush it.
Bringenginetoitsnormaloperatingtemperature.
CAUTION: Never run engine without supplying
water to the exhaust cooling system when wa-
tercraft is out of water.
CAUTION: Failure to flush exhaust cooling sys-
tem, when engine is out of water, may severely
damage engine and/or exhaust system.
WARNING
Engine oil may be hot. Certain components
in the engine compartment may be very hot.
Direct contact may result in skin burn.
CAUTION: Never run engine longer than 5 min-
utes. Drive line seal has no cooling when wa-
tercraft is out of water.
Runenginefor10secondsat4000RPMandshut
it off at this RPM. This will move oil from PTO
housing to oil tank to allow maximum oil draining.
Remove oil filler cap and dipstick.
Using the Oil VAC (P/N 529 035 880), siphon oil
through dipstick hole.
CAUTION: Never crank or start engine when
siphon tube is in dipstick hole. Never start en-
gine when there is no oil in engine.
NOTE: So that siphon tube is located at the proper
height to siphon oil, it is suggested to put some
electrical tape on siphon tube at 475 mm (18.7 in)
from its end. Then, insert siphon tube until you
reach the tape.

1. Oil VAC
2. Siphon tube in dipstick hole
Pull siphon tube out of dipstick hole then crank
engine (do not start) while in engine drown mode
(fully depress throttle lever and HOLD, then crank
engine).
Crank engine for 10 seconds. Siphon oil again.
Repeat the crank-siphon cycle 2 - 3 times.
Inspection
Oil condition gives information about the engine
condition. See TROUBLESHOOTING section.
