Section 3 Fuel System
OS 385
The starboard fuel fills feed the starboard
and center tanks. The port fuel fill feeds the
port tank. The center tank holds approxi-
mately 130 gallons. The Port and starboard
tanks hold approximately 120 gallons each.
All boats equipped with gasoline engines are
required to have anti-siphon valves by the
U.S. Coast Guard.
The fuel delivery lines are
equipped with anti-siphon valves where the
lines attach to the fuel tanks. These valves
help prevent gasoline from siphoning out of
the fuel tank should a line rupture.
DO NOT remove anti-siphon valves from
system. Anti-siphon valves prevent fuel from
flowing into bilge should a fuel hose or fitting
leak. If the valve becomes clogged, clean
and reinstall or replace it.
Fuel Tanks
The fuel pick-up tubes are positioned in the
tanks to achieve optimum fuel usage, fuel
line routing, etc. At certain speeds and hull
trim angles, the fuel supply at the withdrawal
tube 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 trim angle
of the boat may cause the fuel to flow away
from the pickup tubes.
Fuel Gauge Senders
The fuel gauge senders are more accurate
when the boat is stationary and level.
Because of the change in attitude when the
boat is underway, variations in gauge read-
ings can occur. This system is a relative indi-
cation of the available fuel supply and not a
calibrated instrument.
Fuel Fills
A fuel fill deck plate is located on each gun-
wale and is marked “GAS.” The fuel fill is
opened by turning it counterclockwise with a
special key. After fueling, install the fuel cap
and tighten with the key; DO NOT over
tighten. Use only the fuel recommended by
the outboard manufacturer; refer to the
engine owner’s manual for additional infor-
mation.
If fuel is added to any other tank, DO NOT
attempt to pump fuel out, these systems are
not designed to pump fuel. Fuel must be
removed by qualified personal only. Fuel in
other systems will also require replacement
of that system and/or many components.
Fuel Vents
There are two fuel vents for the fuel tanks,
one on each side of the hull. While the tank
is being filled, air displaced by the fuel will
escape from the vents. Do not allow fuel to
be expelled from the vents and pollute our
environment. Fill the fuel tanks slowly and
monitor the fuel gauges while filling. Spilled
fuel can be dangerous.
Wash the areas around the fuel fill plates
and below the fuel vents to help reduce dis-
coloration of fiberglass or striping.
