F. Fuel Senders
figures developed by Four Winns.
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.regis-
ters “empty”, the sender has bottomed out and there
may.be.3.to.4.gallons.of.fuel.in.the.tank...
See.Figure.I-6.
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.
fuel.gauge..See.Figure.I-4.

Figure I-4: 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.

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..The.engine.manual.is.included.
in.the.owner’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.Figure.I-3..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.I-5..
NOTICE
Canister-type filters should be changed
annually.
H. Gas Vapor Detector
A.gas.vapor.detector.is.optional.on.the.348.Vista®.
models..The.gas.vapor.detector.will.monitor.the.
engine.compartment.and.notify.the.operator.of.an.
accumulation.of.gasoline.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 I-5: Effects of Trim Angle
It.is.very.important.to.keep.track.of.hours.and.fuel.
consumption.to.obtain.an.average.gallon.per.hour.
consumption 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.
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.
Dealers are equipped with some general figures on
consumption.which.can.be.used.as.a.guide.until.
specific information on your boat is determined.
Because.of.boating.conditions,.speed,.weight.and.
other.factors.common.to.your.situation,.fuel.consump-
tion.will.vary.between.your.boat.and.consumption.
