the rear fuel fill on the port gunnel. The auxiliary fuel tank is
located forward of the main tank and filled by the forward fuel
fill on the port gunnel. Each fuel withdrawal line is equipped
with an anti-siphon valve where the line attaches to the fuel
tank. This valve prevents gasoline from siphoning out of the
fuel tank should a line rupture.
DO NOT REMOVE THE ANTI-SIPHON VALVES
FROM THE SYSTEM. SHOULD THE VALVE
BECOME CLOGGED, CLEAN AND REINSTALL
OR REPLACE.
A fuel filter for each engine and the fuel selector valves are
installed in the stern bilge. They are accessed through the center
hatch, below the stern seat. The filters are the water separator
type and should be serviced frequently to assure an adequate
supply of clean, dry fuel to the engines. It is recommended
that the filters are inspected periodically and the elements
changed as needed.
There is a primer bulb in each fuel line located near the fuel
filter that is used to prime the fuel system after service or as
required. See Fuel System Maintenance and the engine owner’s
manual for additional information on the fuel filters and the
outboard engine fuel system..
The fuel system is designed with a main and auxiliary fuel
tank. Selector valves in the stern bilge near the fuel filters allow
the operator to select between the main fuel tank, for normal
operation, and the auxiliary fuel supply. The valves also have
an off position for servicing the fuel system.
Fuel Management
Proper fuel management is important on all boats. The main
tank on your boat is much larger than the auxiliary tank and
the boat should be operated from that tank the majority of the
time. However, it is important that fuel in the auxiliary tank is
consumed each time the boat is used so that fresh fuel can be
supplied to both tanks every time the boat is refueled. This will
prevent the fuel in the auxiliary tank from degrading and ensure
that fresh, quality fuel is available from both fuel tanks.
During normal operation, the fuel valves should be set to the
main fuel tank when you begin each trip. On long trips, run on
the main tank until it is half full, then switch to the auxiliary
tank. When the auxiliary tank is half full, switch back to the
main tank. On short trips, run on the main tank on the way out
and the auxiliary tank on the way back.
Avoid letting the fuel level in either tank from get below 1/4
tank. Pay attention to the fuel level in the selected tank and
make sure to switch to the other tank before the engines run
out of fuel. When engines run out of fuel they will shut down
suddenly and you will loose the ability to control the position
of the boat for several minutes while the fuel system is primed
so the engines can be restarted. This could endanger the boat
and crew in rough seas, an inlet or a busy waterway. Always
make sure to return the valves to the main position when you
fill the tanks.
Note: The procedure to prime the fuel system on out-
board engines is specific to the type and model of
engine on your boat. You should refer to engine
manufacturer owner’s manual for the priming
procedure for your engines.
3.3 Diesel Generator Fuel System
(Optional)
The diesel fuel system for the optional generator is completely
separate from the gas system. The diesel fuel tank is located in
the bilge below the bridge deck and is filled from a fuel fill deck
plate on the starboard gunnel labeled “Diesel.” The diesel fuel
system is not equipped with an anti-siphon valve and there is
a fuel return line for the engine that returns unused fuel to the
fuel tank. A separate fuel pump mounted near the diesel fuel
tank supplies fuel from the tank to the generator.
Proper diesel engine operation requires a good supply of clean,
dry diesel fuel. Improper marina fuel storage techniques, lim-
ited boat usage, etc. can cause the fuel to become contaminated.
Periodically, it may be necessary to pump accumulating water
and contaminated fuel from the bottom of the fuel tank. If the
generator fuel system on your boat becomes contaminated, con-
tact your dealer or Scout Customer Service for assistance.
Algae can grow in the accumulated water in diesel fuel tanks.
This condition is most prevalent in warm climates. Periodi-
cally adding a high quality diesel fuel additive containing an
algicide may be required to control algae in your boating area.
You should contact your dealer or the generator manufacturer
for additional information regarding fuels and additives.
