D. Fuel Gauge
NOTICE
When fueling at a marina, DO NOT overfill. Fuel
may spill into the water.
The fuel gauge indicates the amount of fuel in the tank.
See Section E-6F Fuel Gauge for additional information
on fuel gauge use.
After fueling, replace the fill cap, and wash the areas
around the fuel fill plate. Residual fuel left on the deck
andhullsidescanbedangerous,andwillyellowthefiber-
glass. It will also damage the tape stripes and logos.
NOTICE
Fuel gauges are not precision instruments. The
reading is relative, and should never be relied
upon as the sole indicator of fuel availability.
C. Anti-Siphon Valves
E. Fuel Senders
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. See Figure I2 for anti-siphon loca-
tion.
The fuel sender consists of a mechanical arm with float
which measures the fuel in the tank. The sender arm
adjusts with the amount of fuel in the tank and sends a
signal to the fuel gauge. See Figure I3.
Figure I3: Fuel Sender Operation
Due to the mechanical nature of the fuel sender, varia-
tions in readings during various speeds of operation may
occur. This system is merely a relative indication of the
available fuel supply and not a calibrated instrument.
Relative adjustments can be made by your Four Winns®
dealer by bending the fuel sender float arm.

The gauge readings will also vary with the trim angle of
the boat. When sitting at a dock and the boat is nearly
level, the fuel gauge will register accurately. Refer to
Figure I3. When boating, the trim angle of the boat
changes and affects the gauge readings. Under these
conditions, the fuel sender will register “full” for the first
few hours of running time until the fuel level drops below
the 3/4 or 1/2 mark. This is caused by the angle of the
fuel in the tank as shown in Figure I4.
The fuel withdrawals are positioned in the fuel
tanks to achieve optimum fuel usage, and fuel
line routing. 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 oper-
ate the boat on a minimum amount of fuel.
Though some fuel may be in the tank, the rela-
tive trim angle of the boat may cause the fuel to
flow away from the withdrawal.
NOTICE
Access plates or lids are provided in the floor
for easier access to the fuel pickup, anti-siphon
valve and sender.
