Ventilation and Drainage Systems
K - 1 ENGINE COMPARTMENT
VENTILATION
Blower operation can be tested by placing a hand
over the vents. DO NOT rely on the sound of the
blower. Be sure a substantial amount of air is being
exhausted by the bilge blower. Check the bilge blower
system often, preferably before each cruise.
All Four Winns V Series models are equipped with
engine compartment ventilation. This system is
designed to meet or exceed the requirements (in
effect at the time of manufacture) of the US Coast
Guard, the National Marine Manufacturers Associa-
tion, and the American Boat and Yacht Council.
K - 2 CABIN & COCKPIT VENTILATION
The V475 forward stateroom is equipped with a deck
hatch for ventilation. See Figure K1.
A. Natural Ventilation System
This system includes air intake and exhaust com-
ponents. The exhaust ducting reaches to the lower
bilge area. This provides adequate air movement
while underway and during bilge blower operation.
B. Forced Air Ventilation
All Four Winns V Series models are equipped with
an electric bilge blower. The bilge blower provides the
ventilation required prior to starting the engines and
while at idle. See Section H - Electrical Systems for
blower operation instructions.
Figure K1: Deck Hatch
A screen and blind for the forward deck hatch is also
standard. This “layered” deck hatch system allows the
screen and blind to be slid to the desired position with
ease. Also, storage for the screens and blinds are built
into the screen/shade system. See Figure K2.
Before starting the engine(s) or generator,
operate the engine compartment bilge blower
for four (4) minutes. Then check the engine
compartment for fuel vapors. ALWAYS operate
the bilge blower while the engines are at idle or
the generator is in use. Failure to comply could
cause explosion and thereby inflict serious
injury or death.
Fumes can come from batteries while charging.
A concentration of hydrogen fumes can be
explosive under the right conditions. Ensure to
follow the above warning.
C. Engine Ventilation System Maintenance
Figure K2: Screen/Shade System
Periodic inspection and cleaning of the ventilation
ducts is necessary to ensure adequate air circulation.
A buildup of leaves, twigs, or other debris can severe-
ly reduce ventilation. Be sure bilge water does
not accumulate to a level that would obstruct the
ventilation ducts.
NOTICE
Be sure deck hatch is secured while underway.
Damage to the hatch may result.
