Fuel Gauge
The fuel gauges indicate the amount of fuel in the fuel
tanks respectively. See Section E-8F - Fuel Gauge for
additional information on fuel gauge use.
Figure I5: 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. This will prevent any problems with running
out of fuel on the water.
NOTICE
Fuel gauges are not precision instruments. The
reading is relative, and should never be relied
upon as the sole indicator of fuel availability.
Dealers are equipped with some general figures on con-
sumption which can be used as a guide until specific
informationonyourboatisdetermined. Becauseofboat-
ing conditions, speed, weight and other factors common
to your situation, fuel consumption will vary between your
boat and consumption figures developed by Four Winns.
G. Fuel Sender
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 I4.
When the fuel gauge begins to register below the “full”
mark, the gauge readings will drop much faster until it
reads “empty”. When this occurs, the trim angle has
affected the sender reading. When the gauge registers
“empty”, the sender has bottomed out and there may be
3
to 4 gallons of fuel in the tank. See Figure I6.
Figure I4: 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.

H. Fuel Filters
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 I4. 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 I5.
Fuel filters are installed on each engine. Filters should
be cleaned or changed frequently to assure an adequate
supply of fuel to the engine. Refer to the engine manual
foradditionalinformation. The engine manual is included
in the owner’s information packet.
NOTICE
Canister-type filters should be changed annu-
ally.
