SPECIAL PROCEDURES
Jet Pump Water Intake and
Impeller Cleaning
Water is drawn up by the impeller
through these openings. The grate
minimizes entry of foreign objects into
the propulsion system.

TYPICAL — BOTH SIDES
1. Intake grate
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 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 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 inter-
nal engine components.
NOTICE
Avoid operation in
weeded areas. If unavoidable, vary
speed.
Weeds tend to entangle
more at steady and slow speeds.
Inspect water intake grates for dam-
age. Refer to an authorized Sea-Doo
Boats dealer for repair as necessary.
The clogged area can be cleaned as fol-
lows:
Boat Without a Weedless System
In-water Cleaning
Pull the tether cord from engine cut-off
switch 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:
1. With engine(s) running, put shifter
lever in reverse position and vary
throttle
setting quickly several
times.
2. Try accelerating again.
Most of the time, debris will escape
from the propulsion system. If not, re-
fer to
OUT OF WATER CLEANING
.
Out of Water Cleaning
WARNING
Always remove the tether cord
from the engine cut-off switch to
prevent accidental engines start-

Sea-Doo Boats dealer for servicing.
Boat with a Weedless System
Press and hold the weedless system
