This is a safety feature of your boat, to ensure that the
generator never depletes the fuel to the engines.

5.3 Fuel Valves
Your boat has fuel shutoff valves located at the tank in the
supply line route. These valves are used to start or stop
the flow of fuel through the supply lines.
Note: Even if the fuel supply valves are closed, there may be
fuel in the supply lines to the filters and engines (or generator).
Disconnecting these fittings without properly bleeding the sys-
tem of fuel could result in emptying the fuel filters and causing a
fuel spill. Only a qualified technician should ever make repairs
to your fuel system.
The fuel supply valves are the “ball type” valves. Turning
the handle so it is perpendicular to the valve body shuts
off the supply or return. Turning the handle so it is in line
with the valve body opens the valve, as shown in Fig.
5.5.

5.3.1 Fuel Tank Selection Valve
With two fuel tank s the boat is also required with valve
for selecting which tank to draw fuel from. The valves
are located in the first bilge compartment in the main
salon. For fuel tank selection, by rotating both valve
handles for the fuel supply and one for the return. Align
with the placards that mark tank to use.

Note: This configuration may not reflect the configuration of
what your fuel valves are. This can be found in the Fuel System
Arrangement at the end of this chapter.
5.4 Filters (Fuel Water Separators)
The fuel supplied to the engines or the generator (if so
equipped) may contact impurities found in the fuel tanks
or in the fuel from your supplier. If these impurities are
not removed prior to starting the engine or generator, per-
formance may be seriously affected. Removal of the fuel
impurities is accomplished by external fuel filters.
5.4.1 Main Engine Filters
Each engine has a separate filter located away from the
engine. Check the Fuel Arrangement illustration at the
end of this chapter for the exact location of these filters.
An authorized service technician should replace all filters
annually prior to spring launch. They may need more
frequent replacement if you notice poor engine/generator
performance due to contaminated fuel.
