SPECIAL PROCEDURES
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
flotation 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:
– 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 engine
to overheat and damage engine in-
ternal 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 with-
out starting engine. Most of the time,
this will remove the blockage. Start
engine and make sure watercraft oper-
ates 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 per-
formed:
– With engine running and before
applying throttle, put shift lever in
reverse position and vary throttle
quickly several times.
– Repeat procedure if necessary.
On-Beach Water Cleaning
WARNING
Always remove the DESS key from
its post to prevent accidental en-
gine starting before cleaning the
jet pump area.
Place a cardboard or a carpet beside
the watercraft to prevent scratching
when turning the watercraft for clean-
ing.
Rotate the watercraft to any side for
cleaning.
