Section 02 ENGINE
Subsection 09 (COOLING SYSTEM)
NOTICE
Pure antifreeze will freeze at a higher
temperature than the optimal water/antifreeze
mix. A blend of 40% antifreeze with 60% dem-
ineralized water will improve the cooling effi-
ciency. Using water tap instead of demineral-
ized water, would contribute to make deposits
in cooling system and to reduce antifreeze effi-
ciency. This could lead to engine overheating.
To prevent antifreeze deterioration, always use
the same brand. Never mix different brands un-
less cooling system is completely flushed and
refilled.
NOTICE
To prevent rust formation or freez-
ing condition in cold areas, always replenish
the system with 50% antifreeze and 50% dem-
ineralized water. Pure antifreeze will freeze
at a higher temperature than the optimal wa-
ter/antifreeze mix. Always use ethylene glycol
antifreeze containing corrosion inhibitors
specifically recommended for aluminum en-
gines. Using water tap instead of demineral-
ized water, would contribute to make deposits
in cooling system and to reduce antifreeze effi-
ciency. This could lead to engine overheating.
Draining the System
WARNING
Never drain or refill cooling system when en-
gine is hot.
Open seat and remove the rear ventilation box.
Remove t
he coolant expansion tank cap.
Install a drain pan underneath the ride plate.
Unscrewthedrainplugonrideplate.
NOTE: Ra
ising the front of the watercraft will con-
tribute
to drain the cooling system.

1. Cooling drain plug
Dispose coolant as per local regulations.
Do not reinstall drain plug at this time.
Cleaning the System
NOTICE
Cleaning the cooling system as per
the following procedure is required when en-
gine overheats (assuming everything else is
operating normally) or each time coolant is
replaced.
Drain the cooling system. Clean thoroughly using
the Valvoline Zerex Super Cleaner (or equivalent).
Add the cleaning product in coolant expansion
tank then fill cooling system with demineralized
water.
Reinstall cap on coolant expansion tank.
Install watercraft in a test basin or ride on a water
plane. Start engine and run for approximately 15
minutes.
IMPORTANT: Ensure thermostat opens so that
the cleaning product flows in ride plate properly.
Stop engine and let the cleaning product work for
12 to 16 hours.
Thereafter, engine can be run one last time to soak
off deposits.
Drain and thoroughly rinse the cooling system
with clean fresh water.
Refill cooling system as described below.
Refilling the System
Watercraft should be level, engine cold and drain
plug removed for refilling.
Place a container under drain plug to collect an-
tifreeze.
Ask someone to pour recommended antifreeze in
expansion tank.
When antifreeze flows out from the ride plate
drain hole, reinstall drain plug. Torque drain plug
to 8 N•m (71 lbf•in).
Continue to pour and fill expansion tank between
marks.
