VENTILATION & DRAINAGE SYSTEMS
C. Engine Ventilation System Maintenance
K - 1 ENGINE COMPARTMENT VENTILATION
Periodic inspection and cleaning of the ventilation ducts
of leaves, twigs, or other debris can severely reduce
ventilation. Be sure bilge water does not accumulate to
a level that would obstruct the ventilation ducts.
All Four Winns® stern drive models are equipped with
to meet or exceed the requirements (in effect at the time
of manufacture) of the U.S. Coast Guard, the National
Marine Manufacturers Association, and the American
Boat and Yacht Council.
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.
A. Gravity Ventilation System
The exhaust ducting reaches to the lower bilge area.
This provides adequate air movement while underway
and during bilge blower operation.
Should blower noise and vibration be excessive, loos-
ening the bilge blower mounting screws and then tight-
ening evenly usually reduces noise considerably.
B. Forced Air Ventilation
K - 2 HULL DRAINAGE SYSTEMS
A. Transom Drain
All Four Winns® models except outboards are equipped
with an electric bilge blower. The bilge blower provides
the ventilation required prior to starting the engines and
whileatidle. SeeSectionH ElectricalSystemsforblower
A transom drain with plug is provided in the engine com-
partment to allow water drainage. When the boat is out
of the water, the boat and trailer should be positioned so
any bilge water accumulation during dry storage will flow
towards the transom.
Gasoline vapors can explode resulting in in-
jury or death. Before starting the engine, check
the engine compartment bilge for gasoline or
vapors, and operate blower for four (4) minutes,
and verify blower operation. Run blower when
vessel is operating below cruising speed. AL-
WAYS operate the bilge blower while the en-
gines are at idle.
Be sure the drain plug is securely in place prior
to launching the boat. Upon shipment of the
boat, the drain plug is usually taped to the steer-
B. Bilge Pumps
A Gas Vapor Detector is a monitor which will
alert the operator of an accumulation of gaso-
line fumes in the engine compartment. It is op-
tional only on larger models but can be installed
on detectors or similar equipment. ALWAYS
conduct a physical inspection of the engine
Bilge pumps are provided in the bottom of the hull to
remove miscellaneous water accumulations that might
occur during normal boating or weather conditions. The
bilge pump is controlled by the Bilge Pump Switch on
the dash panel. See Section H-3 for a detailed descrip-
tion of the bilge pump switches.
