1. Level between marks when engine is cold
Do not install pressure cap at this time.
Properly cool exhaust system by installing a gar-
denhose. RefertoflushinginMAINTENANCE
section.
Start engine and let run for 2 minutes. Stop en-
gine and wait 15 minutes to cool down. Refill tank
as necessary.

1. This becomes hot when thermostat opens
Last, refill expansion tank and install cap.
When engine has completely cooled down,
recheck coolant level in radiator and coolant tank
and top up if necessary.
Test the density of the coolant using an antifreeze
hydrometer.
NOTE: Follow hydrometer manufacturer instruc-
tions for proper use.
The reading should be some degrees below the
coldest temperature you expect in the area where
the watercraft is to be used. Add demineralized
water or antifreeze accordingly. Refill to the prop-
er level.
CAUTION: Pure antifreeze will freeze at a
higher temperature than the optimal wa-
ter/antifreeze mix. Using water tap instead
of demineralized water, would contribute to
make deposits in cooling system and to reduce
antifreeze efficiency. This could lead to engine
overheating.
