SPECIAL PROCEDURES

Jet Pump Water Intake and
Impeller Cleaning
WARNING
Keep away from intake grate while
engine is running. Items such as
long hair, loose clothing or per-
sonal flotation device straps can
become entangled in moving
parts.
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:
– Cavitation: Engine speed is high
but watercraft moves slowly due to
reduced jet thrust, jet pump compo-
nents may be damaged.
– Overheating: Since the jet pump
operation controls the flow of wa-
ter to cool the exhaust system, a
clogged intake will cause the ex-
haust to overheat and damage ex-
haust components.
A weed clogged area can be cleaned as
follows:
