An.engine.that.is.not.developing.full.power.and.the.load.
carried.in.a.boat.will.directly.affect.performance.of.the.
engine..Always.be.sure.the.engine.is.properly.tuned.

before.changing.propellers.
For.additional.information.on.factors.affecting.perfor-
mance,.please.consult.your.Four.Winns.dealer.
E - 5 RUNNING ANGLE & POWER
TRIM/TILT
Hull.planing.surfaces.have.the.least.amount.of.drag.
at a three to five degree angle with the water. This is
the.preferred.running.angle.when.boating..The.run-
ning angle has a significant impact on top speed and
handling..See.Figure.E-2..Heavy.load.or.certain.water.
conditions may make it difficult to achieve the optimum
running.angle..The.running.angle.can.be.controlled.
through.the.use.of.the.power.trim..
A. Power Trim
Trim.angle.is.how.far.in.or.out,.the.drive.is.positioned..
in.relation.to.the.bottom.of.the.boat..The.trim.angle.of.
the.drive.has.a.distinct.affect.on.the.running.angle..
of.the.boat..
The.power.trim.system.permits.control.of.the.trim.angle.
of.the.drive.relative.to.the.boat,.at.the.touch.of.a.button..
It.allows.the.drive.to.be.raised.for.shallow.water.opera-
tion..Power.trim.also.allows.the.operator.to.adjust.the.
drive.while.underway.to.provide.the.ideal.running.angle.
for.a.given.load.and.water.condition..Additional.infor-
mation.can.be.found.in.the.engine.operator's.manual.
included.in.the.owner's.packet..
B. Power Tilt
Power.tilt.allows.the.operator.to.raise.and.lower.the.
drive..for.trailering,.launching,.and.beaching..Additional.
information.on.power.tilt.can.be.found.in.the.engine.
operator's.manual.included.in.the.owner's.packet.
NOTICE
DO NOT operate the motor with the water
intakes out of the water. Severe damage to the
engine systems can result. Consult the engine
operator's manual for specific information.

E - 6 TRIM TABS
Electric/hydraulic.trim.tabs.are.available.on.certain..
models...Check.with.your.dealer.for.availability.on.
your..model..Trim.tabs.help.provide.maximum.control.
of.the.hull.in.all.water.and.load.conditions..Used.
properly,.trim.tabs.can:.
a.. Compensate.for.wind.and.load.listing.(level.the.
boat.side.to.side).
b.. Induce.faster.planing.and.help.achieve.optimum.
running.angle.(see.Section.E-5.-.Running.Angle.
&.Power.Trim/Tilt).
The.proper.use.of.electric/hydraulic.trim.tabs.requires.
a.basic.understanding.of.trim.tab.operation.and.some.
practice.in.calm.water..Be.sure.to.read.the.manufac-
turer's.literature.included.in.the.owner's.packet.
The.trim.tab.control.uses.two.(2).momentary-type.
rocker.switches...The.trim.tab.switches.control.the.
attitude.or.position.of.the.boat...The.trim.tab.switches.
are.labeled.by.position.such.as."Bow.Up".and."Bow.
Down"..They.are.also.labeled.for."Port".and."Stbd"....
When.pressed,.the.label.indicates.what.happens.to.
the.bow.of.the.boat.
