through this opening. The grate mini-
mizes entry of foreign objects into the
propulsion system.

TYPICAL
1. Intake grate
WARNING
Keep away from intake grates
while engines are on. 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 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:
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.
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 Boats dealer for servic-
ing.
NOTICE
Avoid operation in weed-
ed
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.
Towing the Boat in Water
Special precautions should be taken
when towing a Sea-Doo Sport Boats in
water.
Maximum
recommended
towing
speed is 24 km/h (15 MPH).
