Exhaust System Flushing

To prolong engine life it is very important to
flush the engine of salt water after use and
prior to storage. Failure to carry out flushing
will significantly reduce the life of engine
components and may invalidate the warranty.
In addition, it is advised to thoroughly wash
with fresh water around the jet pump area to
remove all salt deposits after use.
Flushing the exhaust system with fresh water
is essential to neutralize corroding effects of
salt and other chemical products present in
water. It will help to remove sand, salt, shells
and other particles in water jackets, exhaust
system, intercooler (supercharged engines)
and hoses.
Exhaust system flushing should be performed
when the boat is not expected to be used
again the same day or when it is stored for an
extended period of time.
CAUTION. Failure to flush the
system as necessary will severely
damage the exhaust system.
WARNING. Perform the flushing
procedure in a well-ventilated area.
Certain components in the engine
compartment may be very hot. Direct
contact with hot components may result
in skin burns. Do not touch any electrical
part or the jet pump area when the
engine is running.
