Exhaust system
Inspect all exhaust system com-
ponents (hoses, clamps, mixing
elbow, manifold, etc.) Check for
cracks, leaks and corrosion. Tight
or change them if necessary.
Check for carbon or soot residue on
exhaust components as it indicates
an exhaust leak.
If any defect appears on compo-
nent of the exhaust system, change
it as there's a risk of exhaust
leakage or water penetration in the
engine and the boat.
Air intake
I WARNING
Carry out these operations when
the engine is stopped and cold.
Make sure that no dust or dirt
enter the intake manifold.
The air filter reduces the level of
noise made by the air intake and
prevent particles from penetrating
the intake manifold.

The reliability and the perform-
ances of the engine depend among
other things on the quantity and the
temperature of the intake air.
To check the air filter:
1. Remove the clamps and re-
move the filter.
2. Clean the inside of the filter with
dry compressed air.
3. If the air filter is damaged,
change it.
4. Install the filter with the clamps.
Make sure the clamps are tight
enough, while not damaging the
filter.
