DRAINAGE SYSTEMS
9.1 General
Most water is drained by gravity to overboard
thru-hull fittings located in the hull sides above
the waterline. The cockpit, engine hatch and rear
compartments drain by gravity to overboard thru-
hull fittings in the hull sides. 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.
9.2 Bilge Drainage
There are four bilge pumps located in the engine
compartment, cabin, and bow below deck stor-
age compartment. The bilge pumps are activated
both manually by switches in the helm station and
automatically by float switches located near the
pump or integrated automatic switches. The auto-
matic switches are connected to the house battery
bank. They are protected by “push to reset” circuit
breakers in the battery switch breaker panel and
remain activated when the battery switches are in
the OFF position and the batteries are connected.
The manual switches are supplied current when
the HOUSE battery switch is activated. They are
protected by a breaker in the helm accessory
breaker panel.
All bilge pumps pump water out of thru-hulls lo-
cated above the waterline in the hull sides. The
aft bilge pump and automatic switch are located
near the transom, between the engines. The
emergency bilge pump is located just forward of
the aft bilge pump and the automatic switch for
the pump and high water alarm is on a shelf below
the engine compartment step. The forward pumps
with integrated automatic switches are located in
the bilge below the aft berth in the cabin and in
the bow below deck storage compartment.
The manual bilge pump switches should be acti-
vated briefly each time the boat is used. This will
ensure that the pumps are operating properly and
increase the service life of the pumps.
The automatic switches should be manually ac-
tivated periodically to verify operation. This is
particularly important before operating the boat

switches are manually activated by pressing the
test knob on the side of the external switches. The

pump automatic switches are activated by touch-
ing and holding the test button on the side of the
pump for until it activates (about five seconds).
