SPECIAL PROCEDURES
Jet Pump Water Intake
and Impeller Cleaning

WARNING
Keep away from intake grates
while engines are running. Items
such as long hair, loose clothing
or personal flotation device straps
can become entangled in moving
parts resulting in severe injury or
drowning.
Weeds, shells or debris can get caught
on the intake grates, drive shafts
and/or impellers.
A clogged water
intake 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 the jet pump
operation controls the flow of wa-
ter to cool the exhaust system, a
clogged intake will cause the en-
gine to overheat and damage in-
ternal engine components.
The clogged area can be cleaned as
follows:
In-water cleaning: Pull the DESS key
from DESS post to stop engine(s). Let
the boat stop by itself. Wait a while to
allow weeds or other debris to escape
from grate(s). It may be necessary to
repeat the procedure.
In severe conditions if the above
method does not work, the following
can be performed:
– With engine(s) running, put shifter
lever in reverse position and vary
throttle
setting 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 engine(s)
by removing the DESS key.

WARNING
Always remove the DESS key from
the DESS post to prevent acciden-
tal engines starting before clean-
ing the jet pumps area.
From underneath boat, manually clean
water intakes area. If the system is
still clogged, refer to an authorized
Sea-Doo Sport Boat dealer for servic-
ing.
CAUTION: Avoid operation in
weeded areas. If unavoidable,
vary speed. Weeds tend to en-
tangle more at steady and slow
speeds. Inspect water intake grates
for damage. Refer to an authorized
Sea-Doo Sport Boat dealer for re-
pair as necessary.
Capsized Boat
This boat is designed so that it should
not turn over easily due to its long and
wide dimensions. If the boat ever cap-
sizes, remember that it will continue to
float. It is usually best to remain with
it so you will be more easily located by
others.

WARNING
When boat is capsized, do not
attempt to restart the engines.
Operator and passengers should
always wear approved personal
flotation devices.
Submerged Boat/
Water-Flooded Engine
To limit damages to the engines, per-
form the following procedure as soon
as possible.
Drain bilge.
