DIGITAL CONTROL SYSTEM
Your 250 DC comes equipped with the digital control system discussed in Chapter 3 of this
manual. The switch pod is located on the console forward and outboard of the helm.. The con-
trol unit and accessory fuse block are mounted on the rigging wall behind the console insert and
can be accessed through the opening beneath the helm. The boat’s wiring harnesses are con-
nected to the control unit. A fuse block is provided for accessories not controlled by the control
system through a terminal strip. The terminal strip is labeled, to make it easier to identify the
circuits. Wiring diagrams are provided on pages 10-11 to help you to trace circuits when
needed.
BILGE PUMPS / FLOAT SWITCHES
Your 250 DC is equipped with two 1500 GPH bilge pumps. Each pump is connected to a
float switch which automatically triggers the pump when water comes to rest in the bilge. The
float switches are connected to the battery management panel through the hull harness and
receive power from the fuses along the top of the panel. These fuses are constantly energized
and ensure the safety of your boat even when the battery switches are in the “off” position. The
pumps can be manually engaged using the switch pod located on the console.
The bilge pumps are located behind the aft rigging compartment and can accessed through
the inspection plates in the motorwell, forward of the engines. The wiring for these pumps is
secured on the inboard side of the centerline stringer which is visible from the inspection port.
Inspect the operation of your bilge pumps and their connections at least annually. To do so,
activate the pump by momentarily lifting the arm on the float switch, then check the operation
using the switch pod. When testing, do not allow the pumps to run dry for more than two to
three seconds. Extended dry operation can result in damage to your pump. Keeping your bilge
areas clean can also help extend the life of your pump.
FRESHWATER SYSTEM
The freshwater pump and wiring are located in the aft rigging compartment on the starboard
side and can be accessed through the inspection hatch beneath the fishbox. The freshwater
pump is connected to the 8 gallon freshwater tank located under the helm. To access the fit-
tings, use the inspection port located in the starboard storage compartment forward of the
helm. The tank is filled through a fitting located on the vertical wall outboard of the helm chair.
Similar to residential well pumps, the freshwater pump pressurizes the system to 45 psi. then
shuts down until the pressure drops below that level. Most owners leave the pump “on”
throughout the day, and use the system when necessary. On the 250 DC, the freshwater pump
feeds the cockpit shower located aft and outboard of the helm seat and the optional marine head
if installed. To view the layout of the freshwater system see the drawing on page 13.
