SPECIAL PROCEDURE
Engine Overheating
CAUTION: If the monitoring beeper
continuously sounds, stop engines
immediately .
Perform the JET PUMP WATER IN-
TAKE AND IMPELLER CLEANING
PROCEDURE in this section.
Flush exhaust cooling system, refer to
POST-OPERATION CARE.
If engines still overheat, refer to an au-
thorized Sea-Doo sport boat dealer for
servicing.
Inlet Clearance System
(ICS)
Weeds, shells or debris can get caught
on the intake grates, drive shafts
and/or impellers. A clogged water in-
take may cause troubles such as:
1. Cavitation: Engine speed is high
but boat moves slowly due to re-
duced jet thrust;
jet pump compo-
nents may be damaged.
2. Overheating: Since jet pump oper-
ation controls the flow of water to
c o o l e a c h e n g i n e ’s e x h a u s t ,
clogged intakes will cause the en-
gines to overheat and damage inter-
nal engine components.
The clogged area can be cleaned as
follows:
Inlet Clearance System (ICS): Place
shifter in neutral position.
Let the
boat stop by itself then push the ICS
button. This will lower the water intake
grates to allow weeds or other debris
to escape from grates. Grates will open
and retract automatically with a 10-sec-
ond delay before returning to the
closed, or up position. It may be neces-
sary to repeat the procedure.
After releasing ICS button, wait about
10 more seconds before moving
shifter into either forward or reverse to
allow grates to return to the up posi-
tion, completing the cycle.
CAUTION: Operating the boat with
the water intake grates in lower po-
sition will cause damage to the ICS.
In severe conditions if the above meth-
od does not work, the following can be
performed:
– With engines running, put shift le-
ver in reverse position and vary
throttles quickly several times.
– Try accelerating again.
Most of the time, debris will escape
from the propulsion system.
Out of water cleaning: If the system
is still clogged, shut off the engines by
removing the safety lanyard.
From underneath boat, manually clean
each water intake area. If the system
is still clogged, refer to an authorized
Sea-Doo sport boat dealer for servic-
ing.

WARNING
Keep away from intake grates
while engines are on. Items such
as long hair, loose clothing or per-
sonal flotation device straps can
become entangled in moving
parts resulting in severe injury or
drowning.

WARNING
Always remove safety lanyard from
DESS post to prevent accidental en-
gine starting before cleaning the jet
pump area.
