DIGITAL CONTROL SYSTEM
Your 270 SD comes equipped with the digital control system discussed in Chapter 3 of this
manual. The switch pod is located on the console forward of the helm. The control unit and
accessory fuse block are mounted behind the console insert and can be accessed using the
opening beneath the helm. The boat’s wiring harnesses are connected to the control unit. A fuse
block is provided for accessories not controlled by the control device through a terminal strip.
The terminal strip is labeled to make it easier to identify the circuits. Wiring diagrams are pro-
vided on pages 11-12 to help you to trace circuits when needed.
BILGE PUMPS / FLOAT SWITCHES
Your 270 SD 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. The freshwater
pump is connected to the 20 gallon freshwater tank also located beneath the console forward of
the fuel tank. The tank is filled through a fitting located on the starboard vertical wall near the
helm. 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 270 SD, the freshwater pump
feeds the cockpit shower located beneath the helm seat, and the marine head. To view the lay-
out of the freshwater system see the drawing on page 13.
