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 in-
take may cause troubles such as:
1.
Cavitation:
Engine speed is high
but watercraft moves slowly due to
reduced jet thrust, jet pump com-
ponents may be damaged.
2.
Overheating:
Since the jet pump
operation controls the flow of water
to cool the engine, a clogged intake
will cause the engine to overheat
and damage engine internal com-
ponents.
A weed clogged area can be cleaned
as follows:
In-Water Cleaning
Rock the watercraft several times
while repeatedly pressing start/stop
button for short period without start-
ing engine. Most of the time, this will
result in letting the weeds fall from the
intake area. Start engine and make
sure water flows out from bleed out-
let(s) and watercraft operates proper-
ly.
GTS/GTI/GTX Models Only
If the afore mentioned method does
not work, the following can be per-
formed:
– With engine running, put selector
lever in reverse position and vary
throttle quickly several times.
– Retry.
On-Beach Cleaning
Place a cardboard or a carpet beside
the watercraft to prevent scratching
when turning the watercraft for clean-
ing.
Rotate the watercraft
counterclock-
wise
(seen from rear) to its left side
for cleaning. Rotating watercraft coun-
terclockwise eliminates the possibility
of residual water in the tuned pipe en-
tering the engine and causing engine
damage.
Clean the water intake area. If the sys-
tem is still clogged, refer to an autho-
rized dealer for servicing.
◆
WARNING
Always remove safety lanyard
cap from switch to prevent acci-
dental engine starting before
cleaning the jet pump area.
