tends.to.“plow”.(Figure.T-3..The.lower.unit.is.

A.good.practice.is.to.get.underway.(especially..
when.fully.loaded.or.pulling.a.skier).with.the.unit.

Trim.also.affects.propeller.selection.and.fuel.ef-.
ficiency. All models should be “propped” to be in
the.upper.half.of.the.maximum.rpm.range.with.the.
boat.lightly.loaded.and.the.drive.trimmed.up.to.
maximum..

This configuration allows the engine to operate
within.the.recommended.rpm.range.with.a.heavy.
load..
Remember.that.most.boats.react.very.slowly.to.trim.
tabs..Often.boat.owners.do.not.give.trim.tabs.time.to.
work..Press.the.trim.tab.switches.for.only.one.second.
at.a.time.and.then.allow.some.time.for.the.boat.to.
react..If.the.boat.is.still.listing.after.a.minute.or.two,.
press.the.trim.tab.switch.again.for.a.one.second.inter-
val..The.labels.on.the.trim.tab.switches.indicate.what.
you.want.your.boat.to.do,.not.what.you.want.the.tabs.
to.do..
.
The.power.unit.should.never.be.trimmed.up.to..
a.point.where.the.propeller.cavitates.(or.slips)..
A.rapid.increase.in.engine.rpm’s.is.evidence.of.
cavitation..If.this.occurs.accidentally.while.running.
at.full.throttle,.immediately.lower.the.drive.trim.and.
reduce.the.throttle.until.the.slipping.stops..If.nec-
essary,.have.your.dealer.reset.the.trim.limit.switch.
(if.provided).to.avoid.overtrimming.in.the.future..
It.is.a.good.idea.to.take.your.boat.out.onto.open.water.
shortly.after.you.get.it.and.experiment.with.the.trim.
tabs..After.you.get.your.boat.onto.plane,.set.the.tabs.
in.various.positions.and.note.how.your.boat.reacts..
This.will.give.you.a.feel.for.how.the.trim.tabs.work..
.
If.the.prop.slips.at.lower.planing.speeds,.the.drive..
may.be.trimmed.too.high..Immediately.lower.the.
drive.unit.until.the.prop.grabs.again.to.restore.ef-
ficiency.
It.is.possible.to.extend.the.cylinder.life.expectancy.on.
your.trim.tabs..To.do.this,.keep.the.cylinders.retracted. 7... .Trimming.out,.in.addition.to.raising.the.bow,.also.
while.at.dockside..Press.both.trim.tab.controls.down.
until.tabs.reach.their.full.up.position..

B. Tilt/Trim Control Switches
8... The.trailering.position.of.some.stern.drives.is..
controlled.by.a.separate.switch.on.the.dash.switch.
panel.or.throttle/shift.control..Do.not.activate.this.
switch.while.engine.is.running..Doing.so.can.se-
verely.damage.the.lower.unit.and.engine..
NOTE:.Trim.refers.to.the.angle.of.the.lower.unit.in.
relation.to.the.bottom.of.the.boat..With.respect.to.trim-
ming,.the.words.in,.down,.under,.and.forward,.have.
the.same.meaning.as.do.up,.out,.and.aft..
NOTE:.Refer.to.the.control.instructions.regarding.the.
power.trim.controls.installed.on.your.boat..
