SYSTEM OPERATIONS-5
BILGE PUMP SYSTEM
The purpose of the Bilge Pump System
is to remove any water that may accumu-
late within the bilge area of your yacht.
Although a small amount of water in the
bilge area is expected, the water should
never be above the bilge switch. If it does,
it means the switch is not working cor-
rectly. Make sure they are not turned OFF.
If the problem continues, please contact a
service technician to solve the problem.
The bilge area is defi ned as the interior
area of the hull, below the designed water-
line. Your 43SB is equipped with three (3)
bilge pumps that are capable of pumping
1950 gallons of water per hour. The bilge
water is pumped directly overboard.
Normal operation of the bilge pumps is au-
tomatic. Each bilge pump is equipped with
a fl oat-type switch that will automatically
activate the pump when the bilge water
reaches a certain level. The automatic
switches are connected directly to the bat-
teries and will operate even if the battery
switch is turned OFF. Each of the bilge
pumps can also be activated manually
by individual switches located on the DC
Electrical Panel (See the Electrical Pages
in this section of your Owner’s Manual for
the location of the Bilge Pump Switches).
The bilge pump will operate continuously
until the manual switch is turned OFF. The
battery switch must be turned ON to oper-
ate the bilge pumps manually.
Periodic maintenance of the bilge pumps
should consist of the following:
Visually inspect each bilge pump for
any debris that may have accumulated.
Remove any debris noted.
Manually test each bilge pump by acti-
vating the manual switches located on
the DC Electrical Panel. Listen to each
bilge pump as it is manually activated.
They should emit a quiet “whirring”
sound. If any abnormal sounds are
noted, contact your Silverton Dealer for
further inspection and replacement, if
necessary.
IMPORTANT: After testing each bilge
pump by turning ON the manual switches,
be certain they are turned OFF. The
constant operation of the bilge pumps will
eventually discharge the batteries.
While underway the aft bilge pump should
be used. While docked, the midships bilge
pump should be used.
Location of the bilge pumps is as follows:
•FORWARD PUMP - Access to the for-
ward pump is through the hatch opening
located on the Forward Stateroom Floor.
•MIDSHIP PUMP - Access to the mid-
ship pump is through the engine room.
The pump is located in the forward section
of the engine room.
•AFT PUMP - Access to the aft pump is
through the hatch located at the cockpit.
