SPECIAL PROCEDURES

Engine Overheating

If the monitoring beeper sounds con-
tinuously, stop engine immediately.
Perform Jet Pump Water Intake and
Impeller Cleaning procedure shown
in this section.
Flush cooling system, refer to POST-
OPERATION CARE.
If engine still overheats, refer to an au-
thorized dealer for servicing.
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 properly.

GTS, GTI and GTX Limited
If the aforementioned method does
not work, the following can be per-
formed:
– With engine running, put shift 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.
Always remove safety lanyard
cap from switch to prevent acci-
dental engine starting before
cleaning the jet pump area.
SPX, GS, GTS and GTI Models
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.
