Water Flow in Exhaust
Manifold
(only when temperature is
below or close to freezing
point)
In Northern areas, if watercraft is to be
used when temperature is below or
close to freezing point (0°C (32°F)) or if
watercraft was left unused while tem-
perature was below or close to freez-
ing point, water may be frozen in the
supply hose going to the exhaust man-
ifold. This could cause exhaust cooling
system overheating. To ensure it is
properly working, do the following pri-
or to using thoe watercraft:
– The procedure is to be performed
with watercraft out of water.
– Connect a garden hose to the flush-
ing connector at jet pump.
– Perform the flushing operation as ex-
plained in POST-OPERATION CARE.
– Ensure water flows out of jet pump.
Otherwise, water is frozen in supply
hose and restricts water flow. Do
not operate the watercraft in this
condition.
NOTE: Pay attention that some water
will also flow out of exhaust outlet.
Make sure water is effectively flowing
out of jet pump.
CAUTION: Operating watercraft with
frozen water in supply hose might
lead to engine components damage.
NOTE: When water freezes, no dam-
age to engine components will occur
as water expands but it may cause
damage by preventing full flow of cool-
ing water.
– Either wait until ice melt or pour some
hot water on supply hose going to ex-
haust manifold. Then, perform the
flushing operation again to make sure
water properly flows out of jet pump.
If you need asssitance, refer to an au-
thorized Sea-Doo dealer.
– Ensure to drain bilge if water is present.

WARNING
Do not use any electrical heating
device to heat the hose. Electrical
devices may generate sparks that
would ignite fuel vapors that might
be present in the bilge causing a
fire or an explosion.
