SPECIAL PROCEDURE
Engine Overheating
CAUTION:
If the monitoring beeper
continuously sounds,
stop engine im-
mediately
.
Perform the JET PUMP WATER IN-
TAKE AND IMPELLER CLEANING
PROCEDURE in this section.

OPERATION CARE.

thorized Sea-Doo sport boat dealer for

Jet Pump Water Intake and
Impeller Cleaning
Weeds, shells or debris can get caught
on the intake grate, drive shaft and/or
impeller. A clogged water intake may
cause troubles such as:
1.
Cavitation:
Engine speed is high
but boat moves slowly due to re-
duced jet thrust;
jet pump compo-
nents may be damaged.
2.
Overheating:
Since the jet pump op-
eration controls the flow of water to
cool the engine exhaust, a clogged
intake will cause the engine to over-
heat and damage internal engine
components.
The clogged area can be cleaned as
follows:
In-water cleaning:
Pull safety lanyard
from DESS post to stop engine. Let the
boat stop by itself. Wait a while to allow
weeds or other debris to escape from
grate. It may be necessary to repeat
the procedure.
In severe conditions if the above meth-
od does not work, the following can be
performed:
– With engine running, put shift lever
in reverse position and vary throttle
setting quickly several times.
– Try accelerating again.
Most of the time, debris will escape
from the propulsion system.
Out of water cleaning:
If the system
is still clogged, shut off the engine by
removing the safety lanyard.
From underneath boat, manually clean
water intake area. If the system is still
clogged, refer to an authorized Sea-Doo
sport boat dealer for servicing.
CAUTION:
Avoid operation in weed-
ed areas. If unavoidable, vary speed.
Weeds tend to entangle more at
steady and slow speeds. Inspect wa-
ter intake grate for damage. Refer to
an authorized Sea-Doo sport boat
dealer for repair as necessary.
WARNING
Keep away from intake grate while
engine is on. Items such as long
hair, loose clothing or personal flo-
tation device straps can become
entangled in moving parts result-
ing in severe injury or drowning.
WARNING
Always remove safety lanyard from
switch to prevent accidental engine
starting before cleaning the jet
pump area.
