down a stationary tube which measures the fuel in the
tank. The float measures the level of the fuel in the tank
and sends a signal to the fuel gauge. See Figure I3.
C. Anti-Syphon Valves
The fuel withdrawal line is equipped with an anti-syphon
valve where the line attaches to the fuel tank. This valve
prevents gasoline from syphoning out of the fuel tank
should a line rupture. See Figure I2 for anti-syphon lo-
cation.
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.
With this type of sending unit a more accurate mea-
surement of fuel level is obtained with the boat in a
level position.
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.
Figure I2: Fuel Tank Fittings
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.
Figure I4: Effects of Trim Angle
It is very important to keep track of hours and fuel con-
sumption to obtain an average gallon per hour consump-
tion figure. Refer to the fuel log located at the back of
this manual. This will prevent any problems with run-
ning out of fuel on the water.
NOTICE
Access plates or lids are provided in the floor
for easier access to the fuel pick-up, anti-syphon
valve and sender.
D. Fuel Gauge
The fuel gauge indicates the amount of fuel in the tank.
See Section E-7F - Fuel Gauge for additional informa-
tion on fuel gauge use.
