Flushing the exhaust system and in-
tercooler (supercharged models) with
fresh water is essential to neutralize
corroding effects of salt or other chem-

help to remove sand, salt, shells or
other particles in water jackets and/or
hoses.
Flushing should be performed when
the watercraft is not expected to be
used further the same day or when the
watercraft is stored for any extended
time.
WARNING
Perform this operation in a well
ventilated area.
Proceed as follows:
Clean propulsion system by spraying
water in its inlet and outlet and then
apply a coating of XPS Lube or equiva-
lent.
CAUTION When operating the
engine while the watercraft is out
of the water, the heat exchanger in

tor located at the rear of watercraft (on
the port side of the stern). Do not open
water tap at this time.
NOTICE

before opening the water tap. If not,
