3. On the DC Control Center, switch the System DC
Main circuit breaker "ON", then switch the Fuel
Transfer Pump circuit breaker "ON". The pump is
located in the engine room on the port, aft bulk-
head. Refer to the "Interior Hatches" portion of
Section 9 for the location of this hatch.
4. Check the fuel gauges at the helm station. Identify
the fuel tank that has the highest fuel level.
5. Turn the fuel transfer switch, located on the helm
instrument panel, to the fuel tank to which you
want the fuel to flow.
6. Monitor the fuel gauges as the fuel transfers. When
the fuel levels in the tanks are equal, stop transfer-
ring fuel.
Fuel Shut-Off Valves
Fuel shut-off valves are included with the diesel fuel
system. The valves are installed between the fuel lines,
both supply and return, and the fuel tank that they are
connected to. The valves are located on top of the fuel
tanks and must be open when operating the engines.
Do not operate the diesel engine with the return line’s
fuel shut-off valve closed. Doing so creates excessive
pressure within the fuel system that could lead to fuel
system failure.
Each fuel tank, for both gasoline and diesel fuel sys-
tems, is vented overboard. As the fuel tank is filled, air
is displaced from inside the tank and escapes through
the vent. Refer to the "Thru-Hull Fittings" portion of
Section 9 for the location of the fuel tank vents.
Your boat’s engine room is equipped with a ventilation
system consisting of intake ducts, exhaust ducts and
bilge blowers. This system is designed to remove any
fuel vapor from the engine room before you start the
engines or optional generator.
