VENTILATION SYSTEM

10.1 Engine Compartment Ventilation

All Monterey inboard boats are equipped with an
engine compartment ventilation system consist-
ing of intake ducts, exhaust ducts and an exhaust
blower. The ventilation system is designed to meet
or exceed the requirements of the United States
Coast Guard in effect at the time of manufacture
and remove fuel vapors and excess heat from the
engine room.
Free Air System
A flow of air into the engine compartment is pro-
vided by two vents located on either side of the
deck. Exhaust ventilation designed into the vents
provides a flow of air out of the engine compart-
ment. The exhaust area of the vents have ducts
that reach to the lower part of the engine com-
partment. This provides adequate air movement
while operating at or near cruise speeds.
The vents are designed with special baffles that
prevent seawater or spray from entering the
engine or storage compartments while providing
adequate air movement for the engine. The air
flow from the port vent flows from the deck vent,
through the port transom storage compartment
and then to the engine compartment through
vents in the side of the inside wall of the com-
partment. Therefore, it is important not to fill
Port Side Engine Compartment Vent
this compartment with dunnage to the point the
stowed items severely restrict the air flow.
Forced Ventilation
An electric blower provides ventilation to the en-
gine compartment prior to start up of the engine
and while operating below cruise speed.
blower is activated by a switch at the helm and
is located in the vent hose on the starboard side
of the engine compartment. When activated, the
blower will remove bilge fumes through the bilge
exhaust vents. Refer to the Electrical Systems
chapter for more information on blower opera-
tion.
