DRAINAGE SYSTEMS
7.1 General
Most water is drained by gravity to overboard thru-
hull fittings located in the hull sides above the
waterline. You should check the drain system
frequently to ensure it is free flowing and that the
hoses on the thru-hull fittings are secure and not
leaking.
7.2 Bilge Drainage
There are three bilge pumps, (forward, mid, and
aft,) that are activated automatically by float
switches located next to the pumps. A fourth
manually activated aft bilge pump is located in
the stern next to the automatic pump. It is acti-
vated manually by the aft bilge switch in the helm
station. The automatic float switches are con-
nected to the house battery. They are protected
by “push to reset” circuit breakers in the battery
switch panel and remain activated when the bat-
tery switches are in the “OFF” position and the
batteries are connected. The manual switch is
supplied current when the house battery switch
is activated. It is protected by a breaker in the
helm switch breaker panel.
All bilge pumps pump water out of thru-hulls lo-
cated above the waterline in the starboard side
of the hull. The aft bilge pumps and automatic
switch are located near the transom, between
the engines, the mid bilge pump and automatic
switch are in the aft cabin bilge below the rear
berth and the forward pump and automatic switch
are located below the access plate in the forward
cabin sole.
The aft bilge pump system near the transom con-
sists of two pumps and an automatic float switch.
One pump, that is fully automatic, is activated by
the float switch. There is no manual switch for
this pump. The other aft bilge pump is activated
manually by the aft bilge switch in the helm. It is
not activated automatically by the float switch.
The forward and mid bilge pumps are activated
automatically by a float switch next to each pump.
The manual bilge pump should be activated briefly
each time the boat is used. This will ensure that
it is operating properly and increase the service
life of the pump. The automatic switches should
be manually activated periodically, by turning the
test knob on the side of the switch, to verify
operation.
