Failure to properly ventilate the boat while the
engines or generator are operating may permit
carbon monox ide to accumu late inside of the
cabin. Refer to Sec tion E-2 - Engine Exhaust
and Section B-2 - Carbon Monoxide for

HULL DRAINAGE SYSTEMS
A. Transom Drain
A transom drain with plug is provided in the engine
compartment to allow water drainage. When boat is
out of the water, the boat and cradle should be
positioned so any bilge water accumula tion during dry
stor age will flow towards the tran som.
Be sure the drain plug is securely in place prior
to launching the boat. Upon ship ment of the
boat, the drain plug is usually taped to the
steering wheel.
B. Bilge Pumps
Forward and aft bilge pumps are provided in the
bottom of the hull to remove miscellaneous water
accumulations that might occur during normal boating
or weather conditions. See the V458 locator drawing
at the back of this manual. The aft bilge pumps is
controlled by the BILGE PUMP switch located on the
helm switch panel. Refer to Section H for further
information regarding bilge pumps.
The bilge pumps are equipped with an automatic
switch to control pump operation. As the water level
rises, the automatic float switch will activate the pump.
Separate circuit breakers are located at the helm
circuit breaker panel and the aft circuit breaker panel
for the aft bilge pumps. A circuit breaker for the
forward bilge pump is located on the 12VDC panel.
NOTICE
While at rest, any bilge water accumula tion
may flow forward. DO NOT allow bilge water
to accumulate. Damage to the engine or other
compo nents may result. Periodically operate
the bilge pump to remove bilge water
accumulation.
Ventilation and Drainage Systems - Section K
When leaving the boat unattended for long periods of
time or during excessive rain storms, it is a good idea
to check on the boat for excessive water accumula-
tion. Be sure the bilge pumps and automatic float
switches are operating properly. The operating time of
the bilge pumps will be limited to the battery capacity.
Periodically, clean the bilge pump strainers. DO NOT
allow dirt and debris to clog the bilge pump intakes.
Check operation of the bilge pump float switch often to
ensure movement of the switch is not restricted by
debris or other foreign matter.
Wipe up any oil accumu lation in the bilge prior to
activa tion of the bilge pumps. Pumping oil over board
will pol lute the water, and is subject to fine.
After winterization of the fresh water systems, be sure
the bilge area, bilge pumps and associated hoses are
thoroughly dry. Damage to the hull, bilge pumps and
other equipment could occur if water is allowed to
freeze in the bilge. Refer to the manufacturers litera-
ture included in the owner's packet for additional
information.
C. Sump
A forward and aft sump are installed in the floor, just
forward and aft of the fresh water tank respectively.
See the V458 locator drawing at the back of this
manual. These sumps collects gray water from the
various sinks & showers on the boat. Each sump
includes a sump pump which is equipped with an
automatic float switch. The gray water is then pumped
overboard through thru-hull fittings or into the gray
water holding tank (if installed). A pumpout fitting
labeled WASTE but designated for gray water is
provided on the deck for removal at a pumpout
station. Refer to Section J- additional information on
the gray water system.
D. Bilge Compartment Drainage
Certain bulkhead areas of Four Winns
sealed in accordance with US Coast Guard regula-
tions effective at the date of manufacture. Drainage
is provided and water can be removed with the bilge
pump.
