SPECIAL PROCEDURES

Jet Pump Water Intake and
Impeller Cleaning
Water is drawn up by the impeller
through these openings. The grate
minimizes entry of foreign objects into
the propulsion system.

1. Intake grate
WARNING
Keep away from intake grates
while engines are running. Items
such as long hair, loose clothing
or personal flotation device straps
can become entangled in moving
parts resulting in severe injury or
drowning.
Weeds, shells or debris can get caught
on the intake grates, drive shafts
and/or impellers. A clogged water in-
take 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
operation controls the flow of wa-
ter to cool the exhaust system, a
clogged intake will cause the en-
gine to overheat and damage inter-
nal engine components.
NOTICE
Avoid
weeded areas. If unavoidable, vary
speed. Weeds tend to entangle
more at steady and slow speeds.
Inspect water intake grates for dam-
age. Refer to an authorized Sea-Doo
Boats dealer for repair as necessary.
