GENERAL
Refer to the following special procedures accord-
ing to the specific event.
PROCEDURES
TOWING THE WATERCRAFT IN
WATER
Special precautions should be taken when towing
a Sea-Doo watercraft in water.
Maximum recommended towing speed is
24 km/h (15 MPH).
This will prevent the exhaust system from filling
with water, which may lead to water being in-
jected into and filling the exhaust system and the
engine. Without the engine running there is not
any exhaust pressure to push the water out the
exhaust outlet.
NOTICE
Failure to do this may result in dam-
age to the engine. If you must tow a stranded
watercraft in water be sure to stay well be-
low the maximum towing speed of 24 km/h
(15 MPH).
SUBMERGED WATERCRAFT
Drain bilge.
If it was submerged in salt water, spray bilge and
all components with fresh water using a garden
hose to stop the salt corroding effect.
Engine Lubrication
Refer to WATER-FLOODED ENGINE in this sub-
section.
Fuel Inspection
Check fuel tank for water contamination. If nec-
essary, siphon and refill with fresh fuel.
WATER-FLOODED ENGINE
If engine is water-flooded, it must be serviced
within a few hours after the event. Otherwise
engine will have to be overhauled.
NOTICE
– Never try to crank or start the engine. Water
trapped in the intake manifold would enter
the combustion chamber through the intake
valves and may cause damage to the engine.
– A water-flooded engine must be properly
drained, lubricant replaced (oil change), op-
erated (boil out procedure), then lubricant
replaced again, otherwise parts will be seri-
ously damaged.
Whenever the engine is stopped, all the valves
close thus preventing water from being ingested
in the engine.
Exhaust System Draining
If water is suspected to be in the exhaust system,
remove the exhaust pipe and the muffler. Drain
them or siphon the water out of them. Refer to
EXHAUST SYSTEM subsection.
Intake System Draining
If water is suspected in the intake manifold, re-
move the intake manifold and drain it. Then suck
out the water from the intake valve ports. Refer
to
INTAKE MANIFOLD
subsection.
If water is present in the air intake silencer, empty
it.
Remove air intake silencer and check for water
in the supercharger inlet hose. Remove hose to
empty it.
Remove the water from blow-by valve hose.
Throttle Body Lubrication
Throttle body should be lubricated to prevent cor-
rosion.
