.
Perform
Jet Pump Water Intake and
Impeller Cleaning
procedure de-
scribed in this section.

OPERATION CARE.
If engine still overheats, refer to an au-
thorized Sea-Doo 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 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 engine, a clogged intake
will cause the engine to overheat
and damage engine internal compo-
nents.
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 en-
gine and make sure water flows out
from bleed outlet and watercraft oper-
ates properly.
If system is still blocked, move the
craft out of the water and remove
blockage manually.
Models with Reverse System
If the aforementioned method does
not work, the following can be per-
formed:
– 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.
On-Beach Cleaning
All Models
Place a cardboard or a carpet beside
the watercraft to prevent scratching
when turning the watercraft for clean-
ing.
Rotating watercraft in the proper direc-
tion eliminates the possibility of resid-
ual water in the tuned pipe entering
the engine and causing engine dam-
age.
GS, GTS and GTI Models
Rotate the watercraft
counterclock-
wise
(seen from rear) to its
left
side for
cleaning.
WARNING
Always remove safety lanyard cap
from its switch to prevent acciden-
tal engine starting before cleaning
the jet pump area.
