Bilge System
(continued)
Never store anything in the bilges. Storing loose items in the bilges could damage
pumps, pipes or other components that are essential for the proper operation of
your boat.
If you keep your boat in a climate where temperatures can drop below freezing, make
sure that all water within the bilges is drained before you store the boat for the winter.
Water that freezes in the bilges could cause severe damage to your boat and its
components. Refer to Section 8 - Bilges for more information on winterizing the
bilges.

For safety and convenience, each automatic bilge pump can be operated
either automatically or manually.
The bilge pumps remove almost, but not quite, all of the water that collects
within the bilges. If you want your bilges to be completely dry, use a
sponge and bucket to remove the small amount of water that remains.
Your boat is equipped with two high water sensors. If these sensors detect
high bilge water, an alarm sounds. The most likely causes of high bilge
water are: a hull breach, faulty bilge pump or faulty seacock/hose.
Immediately identify and correct the cause of the high water, and remove
the water. Silence the alarm by turning its circuit switch OFF. The switch
is located on the DC Control Panel - Helm.
NOTE: The High Water Alarm circuit breaker on the DC Panel
(Engine Room) must be ON at all times so that the alarm
will sound if there is high water in the bilge.
Incorporated into each automatic bilge pump is an electronic water sensor
switch. The sensor switch automatically turns on the pump when bilge
water rises to a predetermined level. To operate the bilge pumps in
automatic mode:
1. Provide power to the circuit breakers on the DC Panel - Engine Room.
2. On that same panel, switch the Bilge Pump circuit breakers ON.
3. Periodically test each sensor switch by pressing the two indents on the
side of the switch for 4 seconds which should turn the bilge pump on.
