Engines and Instrumentation - Section E
The.hour.meter.is.connected.to.the.ignition.switch..Be.
sure.the.ignition.switch.is.in.the.OFF.position.when.
the.engine.is.not.operating.or.the.hour.meter.will.
record.additional.time.
Figure E-5: Tachometer/Hour Meter
B. Speedometer
The.speedometer.is.a.water.pressure.sensitive.unit..
It.has.a.pick-up.(pitot.tube).assembly.mounted.on.the.
transom.and.a.small.plastic.hose.(speedo.tube).that.
connects.it.to.the.speedometer.gauge.on.the.dash..
See.Figure.E6..The.pitot.tube.extends.below.the.
hull..Water.strikes.the.tube.inlet.and.creates.positive.
pressure..The.faster.the.boat.speed,.the.greater.the.
pressure,.and.the.higher.the.speed.indication.on.the.
speedometer.
Figure E6: Speedo Sender
If.the.pick-up.becomes.clogged,.the.speedometer.will.
not.register..Clean.the.opening.with.a.piece.of.wire.or.
disconnect.the.tubing.and.blow.out.the.pick-up.with.
compressed.air.
When.winterizing.the.boat,.the.speedometer.tubing.
must.be.drained.of.water..Disconnect.the.speedome-
ter.hose.at.the.pick-up.assembly.and.at.the.gauge.
and.blow.through.the.tubing.to.remove.the.water..
NOTICE
Speedometers are not precision instruments.
The indications are relative and should never
be used for navigational purposes or similar
critical situations.
DO NOT rely on the speedometer when trying
to achieve a “NO WAKE” condition in a harbor
or other enclosed waterway. ALWAYS reduce
throttle! Speedometers are not effective at
measuring low operational speeds. You are
responsible for damage caused by the wake
of your boat.
C. Temperature Gauge (4-in-1 Gauge - Twin)
The.temperature.gauge.(included.in.the.4-in-1.gauges.
on.twin.engine.applications).monitors.the.cooling.sys-
tem.of.the.engine..A.sudden.increase.in.water.temper-
ature.could.be.a.signal.of.a.blocked.cooling.passage.or.
a.water.pump.malfunction.
NOTICE
Operation of an overheated engine can result
in engine seizure. If an unusually high tem-
perature reading occurs, shut the engine off
immediately.
D. Oil Pressure Gauge (4-in-1 Gauge - Twin)
The.oil.pressure.gauge.(included.in.the.4-in-1.gauges.
on.twin.engine.applications).indicates.the.pressure.in.
the engine lubrication system. A significant drop in oil
.
pressure.is.a.possible.indication.of.an.oil.pump.or.
other.leakage.problem.
The.engine(s).has.been.equipped.with.an.audible.en-
gine.alarm,.the.alarm.should.sound.if.the.oil.pressure.
drops.below.the.normal.operating.range.of.the.engine..
Please see your engine owner’s manual for specific
engine.information.
NOTICE
Operation of an engine with abnormally low oil
pressure can lead to engine damage and pos-
sible seizure. Have the engine serviced imme-
diately upon a reduced oil pressure indication.
E. Voltmeter (4-in-1 Gauge - Twin)
The.voltmeter.(included.in.the.4-in-1.gauges.on.twin.
engine.applications).monitors.battery.condition.and.
thus.alternator.performance..See.Section.H.for.addi-
tional.information.regarding.electrical.systems.
