Drainage System
9.4 Bilge Drainage & Alarm
There are three bilge pumps, aft, forward and
emergency. The aft and forward bilge pumps
are activated both manually, by switches in the
hardtop switch panel or CZone display, and au-
tomatically by switches built into each pump that
sense the water level at the pump. The auto-
matic switches remain activated when the battery
switches are in the OFF position and the batteries
are connected. They are protected by “push to re
-
set” circuit breakers in the cabin DC breaker panel.
The manual switches are supplied current when
the HOUSE battery switch is activated. They are
protected by fuses in the CZone output modules.
All bilge pumps pump water out of thru-hull fittings
located above the waterline in the hull.
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, by pressing the test button
on the side of pump or flooding the bilge with a
garden hose to verify operation. This is particu-
larly important before operating the boat offshore.
The emergency bilge pump is located above and
to the rear of the aft bilge pump. The pump is fully
automatic and will activate at about the same time
as the high water alarm if the bilge water level
rises above the normal operating range of the bilge
pump automatic switches. The automatic switch
remains activated when the battery switches are in
the OFF position and the batteries are connected.
It is protected by a “push to reset” circuit breaker
in the cabin DC breaker panel.
The emergency pump should be manually acti-
vated periodically, by pressing the test button on
the side of pump to verify operation and increase
the service life of the pump. This is particularly
important before operating the boat offshore.
Notice:
See Electrical Systems for additional infor-
mation on bilge pump operation.
When the boat is out of the water the bilge can be
drained by a garboard drain located in the transom
near the bottom of the hull. The plug should be

removed whenever the boat is hauled out of the
water and installed just prior to launching. It is
important to check the drain plug regularly to
make sure it is tight.
CAUTION
A LOOSE DRAIN PLUG WILL ALLOW SEAWATER TO ENTER THE
BILGE AND COULD CAUSE THE BOAT TO TAKE ON ENOUGH
WATER TO DAMAGE EQUIPMENT OR SINK THE BOAT. IT IS
VERY IMPORTANT TO CHECK THE DRAIN PLUG FREQUENTLY
TO ENSURE IT IS PROPERLY TIGHTENED.
