Once.you.have.spent.enough.time.practicing.maneu-
vers.and.have.a.feel.for.how.the.boat.handles,.you.will.
be.ready.to.run.in.open.waters..
A.few.seconds.at.full.throttle.should.get.the.boat.over.
the.hump.and.into.its.planing.attitude..

speed. This also will provide for better fuel efficiency.

ACCELERATION
S - 7 TRIMMING YOUR BOAT
Before accelerating to bring you boat on
plane, be sure that the area in front of your
boat is clear. The bow will rise out of the water
momentarily before you plane and may tem-
porarily obstruct your vision.
A. Trim Tabs (Applicable Models Only)
Trim.tabs.are.used.to.add.lift.to.the.boat’s.stern,.there-
by.changing.the.boat’s.attitude.(see.Figure.S2)..This.
lift.can.help.the.boat.get.on.plane.faster.and.remain.
on.plane.at.slower.speeds.than.if.no.tabs.were.used..
Used.independently,.tabs.can.also.correct.listing.
conditions.caused.by.crosswinds,.unbalanced.load-
ing.and.quartering.seas..Trimming.your.boat.properly.
involves.two.separate.procedures,.trimming.or.tilting.
the.lower.unit.and.setting.the.trim.tabs..
If.you.have.never.had.your.boat.on.plane.before,.
choose a calm day for your first on plane experience.
Never.boat.beyond.your.ability.and.experience..
Before bringing your boat “on plane”, check the entire
area.to.make.sure.you.have.a.clear,.safe.path..As.
you.throttle.up.to.accelerate,.your.boat.will.increase.
its.angle.of.trim,.causing.the.bow.to.ride.high..From.a.
maximum.angle,.the.boat.will.level.out.to.its.planing.
attitude.with.continued.acceleration..This.maximum.
angle is known as the “hump”. Because visibility, han-
dling,.and.performance.are.reduced,.it.is.advisable.to.
get “over the hump” as soon as possible.
When.you.are.sitting.dead.in.the.water,.your.drive.
should.be.down.and.the.trim.tab.switches.are.in.the.
BOW.UP.position..Accelerate.until.you.get.onto.plane..
At.this.point.your.boat.will.be.plowing.through.the.wa-
ter.with.the.bow.down.too.far..Trim.the.lower.unit.up.
slightly.until.the.bow.comes.up..If.you.trim.the.lower.
