more often. For recommendations regarding cor-
rosion protection for the engine or outdrive, please
refer to the engine owner’s manual.
SOME OUTDRIVES REQUIRE SPECIAL ANODES FOR FRESH
WATER AND A DIFFERENT TYPE OF ANODE FOR SALTWATER TO
PROTECT THE DRIVE FROM GALVANIC CORROSION. CONTACT
THE ENGINE MANUFACTURER OR YOUR MONTEREY DEALER
CAUSE SEVERE DAMAGE TO THE OUTDRIVE. DO NOT PAINT
THE OUTDRIVE OR ALLOW IT TO COME IN CONTACT WITH
YOUR MONTEREY DEALER OR ENGINE MANUFACTURER FOR
INFORMATION ON THE PROPER PAINTING PROCEDURES.
3.3 Engine Exhaust System
Inboard/outboard engines use the exhaust system
to expel exhaust gases and cooling water. Engine
exhaust exits the rear of the boat through the ex-
haust system. The system consists of engine ex-
haust manifolds, exhaust hoses and the outdrive.
A periodic inspection of the coolant hoses, exhaust
hoses and related parts should be made to ensure
that leaks, heat deterioration or damage has not
resulted. Replace them as necessary. Refer to
the engine owner’s manual for more information
on the exhaust system in your boat.
Exhaust Diverter Valves (Optional on
some Engines)
Some models can be equipped with an optional
exhaust diverter valve system that directs exhaust
either through the outdrive and prop or to thru-
hull exhaust ports in the hull sides. Valves in
each exhaust pipe are opened or closed by electric
actuators that are controlled by an Exhaust switch
at the helm.
The thru-hull exhaust ports provide added perfor-
mance and enhanced sound. Using the switch at
the helm, the operator can select the aggressive
sounding thru-hull mode (Exhaust switch ON) or
the quieter thru-prop mode (Exhaust switch OFF).
If this option is installed in your boat, it is im-
portant to change the exhaust from thru-prop to
thru-hull at least once each time the boat is used.
Changing exhaust mode opens and closes the
diverter valves which keeps them free and oper-
ating properly.
DO NOT INHALE EXHAUST FUMES! EXHAUST CONTAINS
POTENTIALLY LETHAL.
