Jet Pump Water Intake And Impeller Cleaning - SeaDoo 2002 GTX 4-TEC Operator's Manual

Jet Pump Water Intake and
Impeller Cleaning
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.
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
watercraft 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 water
to cool the exhaust system, a
clogged intake will cause the en-
gine to overheat and damage en-
gine internal components.
A weed clogged area can be cleaned
as follows:
In-Water Cleaning
Rock the watercraft several times while
repeatedly pressing engine start/stop
button for short period without starting
engine. Most of the time, this will re-
move the blockage. Start engine and
make sure watercraft operates properly.
If system is still blocked, move the wa-
tercraft out of the water and remove
blockage manually.
If the aforementioned method does not
work, the following can be performed:
– With engine running and before ap-
plying throttle, put shift lever in re-
verse position and vary throttle quick-
ly several times.
– Repeat procedure if necessary.
