Reconnect hose when done.
Cooling System Flushing and
Engine Lubrication
Flushing the cooling system with fresh water is
essential to neutralize corroding effects of salt or
other chemical products present in water. It will
help to clean up sand, salt, shells or other particles
in water jackets (engine, exhaust manifold, tuned
pipe) and/or hoses.
Cooling system flushing and engine internal lubri-
cation should be performed when the boat is not
expected to be used further the same day or when
the boat is stored for any extended time.
CAUTION: Failure to flush cooling system,
when necessary, will severely damage engine
and/or exhaust system. Never flush a hot en-
gine. Make sure engine operates during entire
procedure.
WARNING
Perform this operation in a well ventilated
area. Do not touch any electrical parts or jet
pump area when engine is running. Com-
ponents inside engine compartment may be
hot.
CAUTION: Always start the engine before
opening the water tap. Open water tap im-
mediately after engine is started to prevent
overheating.
Proceed as follows:
Clean jet pump by spraying water in its inlet and
outlet and then apply a coating of Bombardier
Lube (P/N 293 600 016) or an equivalent.
WARNING
Always remove safety lanyard cap from post
to prevent unexpected engine starting before
cleaning the jet pump area. Engine must not
be running for this operation.
Connect a garden hose to flushing connector lo-
cated at the rear of watercraft on jet pump sup-
port. Do not open water tap yet.
NOTE: The optional flushing connector adapter
(P/N 295 500 473) can be used with a quick con-
nect adapter to ease garden hose installation.
