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.
The clogged area can be cleaned as fol-
lows:
In-water cleaning: Pull the safety lan-
yard clip from the emergency engine
stop switch to stop engines. Let the
boat stop by itself. Wait a while to al-
low weeds or other debris to escape
from grates. 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 engines running, put throt-
tle/shifter lever in reverse position
and vary throttle setting quickly sev-
eral times.
2. Try accelerating again.
Most of the time, debris will escape
from the propulsion system.
Out of water cleaning: If the system
is still clogged, remove the safety lan-
yard clip from the emergency engine
stop switch to prevent accidental en-
gines starting.
Always remove the safety lanyard
clip from the emergency engine
stop switch to prevent accidental
engines starting before cleaning
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 Boats dealer for servic-
ing.
NOTICE
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
Sport Boats dealer for repair as nec-
essary.
