Inlet and Exhaust System

Intake and exhaust system maintenance is limited to
checking and inspecting the bellows and clamps on the
exhaust system.
Other work on these systems should be done by your
Volvo Penta dealer.

Exhaust Bellows and Clamps

Check the exhaust system according to the frequency
defined in the Maintenance Schedule.
DANGER!
Risk of carbon monoxide poisoning from a leaking
exhaust system. Do not operate the engine with
defective exhaust system components.
Check the clamps C, make sure all are tight.
Inspect the rubber bellows B for signs of over-heating
or deterioration of the rubber. Defective bellows must
be replaced before the boat is used again.
Inspect the exhaust manifolds M, risers R, elbows E,
and pipe P for signs of corrosion.
For replacement of exhaust parts see your Volvo Penta
dealer.

Exhaust Anodes

There is an anode in each exhaust riser, see
illustration.
Riser anodes must be checked yearly or once every
100 hours to determine the amount of erosion that has
occurred. If the anode is more than 1/3 eroded,
replace.
