Fuel Vents
There is a fuel vent fitting on the starboard side of the hull.
While the tank is being filled, the air displaced by the fuel
escapes through the vent. When the tank is full, fuel will be
ejected from the fuel vent.
After fueling, replace the fill cap, and wash the areas around the
fuel fill and below the fuel vent. Residual fuel left on the deck
and hull sides can be dangerous and will yellow the fiberglass
or damage the striping.
3.2 Outboard Fuel System
The fuel system on the Scout has one fuel tank. The 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 VALVE
FROM THE SYSTEM. SHOULD THE VALVE
BECOME CLOGGED, CLEAN AND REINSTALL OR
REPLACE.
The fuel filter is installed in the stern bilge of the boat. It is
accessed through a hatch behind the stern seat. The filter is
the water separator type and should be serviced frequently to
assure an adequate supply of clean, dry fuel to the engine. It
is recommended that the filter is inspected periodically and the
element changed as needed.
There is a primer bulb in the 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 filter and the outboard
engine fuel system..
3.3 Fueling Instructions
FUEL IS VERY FLAMMABLE. BE CAREFUL WHEN
FILLING THE FUEL TANK. NO SMOKING. NEVER
FILL THE TANK WHILE THE ENGINE IS RUNNING.

FILL THE TANK NEAR OPEN FLAMES.
TO PREVENT DAMAGE TO THE FUEL SYSTEM,
USE ONLY A GOOD GRADE OF GASOLINE FOR
OUTBOARD ENGINES. DO NOT USE A FUEL
THAT CONTAINS HARSH ADDITIVES OR IS AN
ALCOHOL BLEND. ANY DAMAGE DONE TO THE
FUEL SYSTEM THAT IS THE RESULT OF USE OF
AN ALCOHOL BLEND, IS NOT COVERED BY THE
SCOUT WARRANTY. REFER TO THE ENGINE
MANUFACTURER OWNER’S MANUAL FOR THE
FUEL REQUIREMENTS FOR YOUR ENGINES.

cedure:
1. Make sure all switches are in the “Off” position.
2. Make sure the boat is securely moored.
3. Make sure all passengers leave the boat.
4. Estimate how much fuel is needed and avoid over
filling the tank.
