Trim.tab.maintenance; Instrumentation; Tachometer/Hour.meter.gauge - Four winns 318 VISTA Owner's Manual

Moving.the.trim.tabs.downward.will.increase.the.lift.
and.the.boat.will.achieve.plane.faster,.or.stay.on.plane.
at.a.lower.engine.and.boat.speed.
After.gaining.plane.and.establishing.cruising.speed,.
pressing.both.lower.trim.tab.switches.will.cause.both.
trim.tabs.to.move.upward.and.will.allow.the.bow.to.
rise..This.should.be.used.to.adjust.the.running.attitude.
of.the.boat.to.decrease.the.drag.at.cruising.speed.or.
above,.or.when.running.in.a.following.sea..When.
running.at.an.engine.speed.that.results.in.the.boat.
falling off plane or causes the boat to plane inefficient-
ly,.lowering.both.tabs.slightly.(bow.down).will.improve.
the running angle and improve operating efficiency.
Optimum efficiency is obtained when operating at a 3
to.5.degree.running.angle..Utilizing.too.much."Bow.
Down" trim tab can reduce operating efficiency and
cause substantial steering and handling difficulties. .
Be.extremely.careful.when.running.in.a.following.sea..
The effect of trim tabs is amplified under such condi-
tions. Steering and handling difficulties can result from
improper.trim.tab.usage,.especially.in.a.following.sea..
If.unsure.of.proper.trim.tab.positioning,.raise.the.trim.
tabs.to.the.full-up.position.
When.running.at.high.engine.speeds,.be.sure.
the.trim.tabs.are.in.the.full.up.position..Trim.tab.
action.should.be.only.enough.to.compensate.
for.any.listing..Trim.tab.adjustments.at.high.
speeds.are.extremely.critical..Be.prepared.to.
slow down should handling difficulties arise.
When.running.in.a.displacement.(very.slow.speed).
mode, better efficiency will be obtained with the trim
tabs.in.the.full-up.position.
C. Trim Tab Maintenance
Check the fluid level of the trim tab reservoir often.
Always keep the fluid level between the designated
marks.on.the.trim.tab.pump-reservoir..Refer.to.the.
manufacturers information for specifications on the
type of fluid to be used and other operation and
maintenance.information.

INSTRUMENTATION

The.helm.station.is.equipped.with.a.complete.set.of.
engine.instruments..These.instruments.allow.the.pilot.
to.constantly.monitor.the.operational.condition.of.the.

engine..Close.observation.of.these.instruments.could.
save.the.engine.from.damage.

A. Tachometer/Hour Meter Gauge
The.tachometers.indicate.the.speed.of.the.engines.in.
revolutions.per.minute.(RPM).and.are.preset.by.Four.
Winns..This.speed.is.not.the.boat.speed.or.necessar-
ily.the.speed.of.the.propeller..They.may.not.register.
zero.with.the.ignition.key.in.the.OFF.position..Note:.
The.318.Vista .models.come.with.a.tachometer/hour.

Engine.Hour.Meter.for.information.regarding.the.
engine.hour.meter.
NOTICE
Never.exceed.the.maximum.recommended.
operating.RPM.of.your.engines..Maintaining.
maximum,.or.close.to.maximum.RPM.for.
extended.periods.can.reduce.the.life.of.the.
engines.
Some.engines.are.equipped.with.devices.that.limit.
engine.RPM.in.accordance.with.the.oil.pressure.or.
engine.temperature..Refer.to.the.engine.owner's.
manual.for.additional.information.
The.tachometer.must.be.set.for.different.engines.
installed..This.is.typically.done.at.the.factory..The.
tachometer.gauge.is.shown.along.with.the.table..
