Figure I4: Fuel Sender Operation
Figure I6: Trim Angle Effect with Low Fuel
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
availablefuelsupplyandnotacalibratedinstrument. With
this type of sending unit a more accurate measurement
of fuel level is obtained with the boat in a level position.
G. Fuel Filters
Fuel filters are installed on each engine. Filters should
changed frequently to assure an adequate supply of fuel
to the engine. Refer to the engine manual for additional
information. Theenginemanualisincludedintheowner’s
information packet.
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 Fig-
ure 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 I5.

H. Gas Vapor Detector
A gas vapor detector is available on the Vista™ models.
The gas vapor detector will monitor the engine compart-
ment and notify the operator of an accumulation of gaso-
line vapors. The operator must take immediate action
upon warning to avoid the possibility of an explosion.
The sensing unit is usually mounted towards the rear of
the engine compartment. The alarm unit is mounted at
the dash.
Figure I5: Effects of Trim Angle
Always personally inspect the engine compart-
ment and sniff for fuel vapors before starting the
engine. Remember, a gas vapor detector is a
mechanical device. DO NOT rely exclusively on
its operation.
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 running
out of fuel on the water.
I.
Use and Maintenance
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.
DO NOT let the odor of gasoline go unchecked.
If the odor of gasoline is noted, DO NOTSTART
ENGINE. If engine is running, SHUT OFF EN-
GINE,ELECTRICALANDHEATGENERATING
EQUIPMENT. Investigate and correct the situa-
tion immediately! Have all passengers put on
personal flotation devices and keep fire extin-
guishers at hand until the situation is resolved.
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.
