FUEL SYSTEM
5.1 General
The gasoline fuel system used in Scout boats
sold in the United States is designed to meet
or exceed the emission control standards of the
Environmental Protection Agency (EPA) and the
requirements of the U.S. Coast Guard, the Boating
Industry Association and the American Boat and
Yacht Council in effect at the time of manufacture.
All gasoline fuel systems have been factory in-
spected and pressure tested in accordance with
regulations in effect at the time of manufacture.
This inspection assures that the system is air tight,
leak proof and safe. It is the responsibility of the
purchaser to maintain it in that condition. Make
frequent inspections to assure that no deteriora-
tion or loosening of connections is resulting from
vibration.
DANGER
DO NOT LET THE ODOR OF GASOLINE GO UNCHECKED. ANY
ODOR OF GASOLINE MUST BE IMMEDIATELY INVESTIGATED
AND STEPS TAKEN TO PROTECT THE BOAT AND ITS
OCCUPANTS UNTIL THE PROBLEM IS CORRECTED. IF THE
ODOR OF GASOLINE IS NOTED, SHUT OFF ALL ENGINES
AND ELECTRICAL EQUIPMENT. INVESTIGATE AND CORRECT
THE SITUATION IMMEDIATELY. HAVE ALL PASSENGERS
PUT ON PERSONAL FLOTATION DEVICES AND KEEP A FIRE
EXTINGUISHER READY UNTIL THE SITUATION IS RESOLVED.
Fuel Withdrawal Tubes
The fuel withdrawal tubes are positioned in the fuel
tank to achieve optimum fuel usage, fuel line rout-
ing, etc. At certain speeds and hull trim angles,
the fuel supply at the withdrawal tank location can
increase or decrease accordingly. Be extremely
careful when attempting to operate the boat when
low on fuel. Though some fuel may be in the tank,
the relative trim angle of the boat may cause the
fuel to flow away from the withdrawal tubes.
The auxiliary/reserve fuel withdrawal tubes are
longer than the main tubes. This provides ap-
proximately 50 gallons of reserve fuel.
Fuel Gauge
Indicates the amount of fuel in the tank. Due to
the mechanical nature of the fuel sender, varia-
tions in readings during various speeds of opera-
tion may occur. This system is merely a relative
indication of the available fuel supply and not a
calibrated instrument.
Fuel Fill
The fuel tank is vented through the fill fitting and
cap. The system is equipped with a “keyless” fuel
cap located on the port side gunnel that is marked
with a “FUEL PUMP” insignia. The fuel fill cap is
designed to seal out water and allow the fuel tank
to vent to the atmosphere when the cap is closed.
The fuel fill is opened by pressing the release but
-
ton on the side of the cap. After fueling, make
sure to close and latch the cap. Be sure to use
the proper type and grade of fuel. Refer to the
engine owner’s manual for additional information.
Fuel Tank Vent
Your boat is equipped with a fuel tank vent system
incorporated into the fuel fill. The fuel fill cap is
designed to seal out water and allow the fuel tank
to vent to the atmosphere when the cap is closed.
While the tank is being filled, air displaced by
the fuel escapes through the vent and fuel fill.
When the tank is full, special valves incorporated
in the vent and fill hoses close and activate the
automatic shutoff valve on the marina fuel pump
nozzle to prevent the tank from being overfilled
