F. Fuel Gauge
The.fuel.gauge.displays.the.level.of.fuel.that.is.present.
in.the.fuel.tank..The.fuel.gauge.will.operate.when.the.
ignition.switch.supplying.power.to.the.fuel.gauge.is.in.
the.RUN.position.
Due.to.the.mechanical.nature.of.the.fuel.sender,.
variations.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..Refer.to.Section.I-1E.-.Fuel.
Senders.for.additional.information.
NOTICE
Use only clean fuel of the type and grade
recommended by the engine manufacturer.
The use of incorrect or contaminated fuel
can cause engine malfunction and serious
damage. Refer to Section I - Fuel Systems
for additional information.
G. Power Trim Gauge
A.trim.gauge.(included.in.the.4-in-1.gauges.on.twin.
engine.applications).is.located.on.the.instrument.
panel..This.gauge.provides.a.visual.indication.of.the.
inward-outward.(trim.angle).position.of.the.outdrive.in.
relationship.to.the.bottom.of.the.boat..There.is.not.a.
trailer.travel.mode.on.the.gauge.
H. Depth Sounder
The.depth.sounder.is.available.standard.on.the.310.
Horizon™ models.
The.depth.sounder.consists.of.two.main.components,.
the.transducer.and.the.depth.sounder..The.transducer.
is.mounted.to.the.hull.and.the.depth.sounder.is.in-
stalled.in.the.dash..The.transducer.and.depth.sounder.
communicate.by.means.of.a.cable,.and.are.powered.
by.your.boat's.12-volt.DC.battery..The.transducer.and.
depth.sounder.use.the.basic.principle.of.sonar..
to.indicate.the.water's.depth.
General description:
1. The.depth.sounder.will.display.depth.of.2-199ft,..
1-92m,.or.1-54F..To.allow.greater.depths.to.
be displayed in the "ft" (Feet) mode, the depth
sounder will automatically change to "F" (Fathoms)
mode.and.continue.to.display.depths.to.approxi-
mately.54.fathoms.
Engines and Instrumentation - Section E
Operation:
1.. Power on..The.depth.sounder.will.activate.auto-
matically.when.the.power.to.it.is.initially.turned..
on..You.do.not.have.to.press.the.combination."ON.
/OFF MODE" keypad. The LCD will illuminate
showing.the.depth.and.will.also.show.the.type.of.
units.selected,.feet.(FT),.meters.(M),.or.fathoms.
(F)..To.turn.the.depth.sounder.off,.press.and.hold.
the "ON / OFF MODE" keypad for 4 seconds.
Pressing the "ON / OFF MODE" keypad again .
will.reactivate.the.unit.
.
NOTE:.The.instrument.is.designed.to.have.the.
internal.LED.lighting.remain.on.as.long.as.power.
is supplied even if the unit is turned "off" at the
keypad.
2. Depth alarm – Shallow mode:.Pressing.the..
"ON / OFF MODE" keypad again displays the "SH"
shallow.depth.alarm.setting..This.is.the.shallowest.
water.that.will.activate.the.alarm..Press.and.hold.
the.up.or.down.arrow.keypads.to.adjust.the.read-
ing.to.the.desired.depth.
.
Depth alarm – Deep mode:.Pressing.the."ON./.
OFF MODE" keypad again displays the "DP" deep
depth.alarm.setting..This.is.the.deepest.water.that.
will activate the alarm. Press and hold the "Up" or
'Down" arrow keypads to adjust the reading to the
desired.depth..When.the.shallow.depth.setting.is.
read by the depth sounder, the "SH" will flash on
the.LCD.and.the.audible.alarm.will.sound.rapidly..
When.the.deep.depth.setting.is.read.by.the.depth.
sounder, the "DP" will flash on the LCD and the
audible.alarm.will.sound.at.2.beeps.per.second.
.
NOTE:.To.fully.deactivate.an.alarm,.reset.it.to.
zero. Pressing the "ON / OFF MODE" keypad
temporarily.deactivates.the.alarm..To.reactivate.
the alarm press the "ON / OFF MODE" keypad
until.the.depth.reading.appears.
3.. Keel offset. Pressing the "ON / OFF MODE"
keypad again displays the "KL" keel offset set-
ting..This.can.be.set.so.that.the.depth.sounder.
either.shows.the.depth.below.the.keel.or.the.depth.
below.the.transducer..Press.the.up.or.down.arrow.
keypads.to.adjust.the.reading.to.the.desired.depth.
no.more.than.19.9.ft..For.example.if.the.bottom.
of.the.keel.is.2.feet.below.the.transducer.and.you.
want.the.depth.sounder.to.read.the.depth.below.
the.keel,.the.display.should.be.adjusted.to.read.
2.0.FT.
