through the Electronic Vessel Control (EVC) system.
An EVC display for each engine is mounted at the
helm and monitors their respective systems to include
fuel level. Refer to the manufacturer’s literature
included in your owner’s packet for specific informa-
tion regarding ECV operation and information display.
The fuel withdrawal is positioned in the fuel
tank to achieve optimum fuel usage, and fuel
line routing. At certain speeds and hull trim
angles, the fuel supply at the withdrawal can
increase or decrease accordingly. Be extremely
careful when attempting to operate the boat on
a minimum amount of 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.
F. Fuel Senders
The fuel sender consists of a float which travels up
and down a stationary tube. The float measures the
level of the fuel in the tank and sends a signal to the
EVC display. See Figure I5.
NOTICE
On the V475 models, access to the fuel fittings
is through the engine compartment.

Figure I5: 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 measurement of fuel level is obtained with
the boat in a level position.
The display readings will also vary with the trim angle
of the boat. When sitting at a dock and the boat is
nearly level, the fuel display 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 I6.
