Section 5: Starting the Pro Boat .18 Engine
Operation
m .3..Turn.on.your.radio.system.and.attach.a.fully.
charged.glow.igniter.(DYN1925).to.the.glow.
plug..Insert.the.starting.wand.into.the.Tiger.
Drive.and.actuate.the.starting.switch.until.
the.engine.begins.to.run..If.the.engine.does.
not.start,.place.your.index.finger.over.the.
carburetor.and.actuate.the.starter.until.you.see.
fuel.enter.the.carburetor.through.the.fuel.line.
Note:.Stop.operation.immediately.
if.the.engine.enters.a.hydro-locked.
condition.as.serious.engine.damage.
may.occur.if.operation.is.continued..
Remove.the.glow.plug,.invert.the.
boat.and.operate.starter.to.remove.
raw.fuel.before.resuming.normal.
operation.
You.may.have.to.“blip”.the.throttle.on.the.
transmitter.(applying.throttle.on/off).while.
trying.to.start.the.engine..New.engines.are.
harder.to.start.because.of.the.tight.piston/
sleeve.fit..Never.start.an.engine.at.1⁄2.to.full.
throttle,.as.this.will.cause.over-revving.which.
may.cause.premature.wear.and.breakage.
During.the.first.tank.of.fuel,.advance.the.idle.
via.the.idle.adjustment.screw.more.than.normal.
to.prevent.stalling.at.idle.due.to.the.rich.
fuel.mixture.for.break.in..Pinch.the.fuel.line.
nearest.the.carburetor.to.stop.the.engine.
Breaking In Your Engine
The.first.start-up.of.the.engine.is.the.most.critical.
moment.of.the.engine’s.life,.dictating.how.the.
engine.will.perform.from.that.time.forward.
During.break-in,.the.low-speed.needle.should.be.
slightly.rich.and.the.high.speed.needle.should.be.
very.rich..After.a.few.tanks.of.fuel,.begin.to.lean.
the.engine.out..Adjust.the.high-speed.needle.1⁄16.
of.a.turn.at.a.time..It.generally.takes.about.five.
to.six.tanks.of.fuel.before.you.want.to.lean.out.
the.engine.until.it.supplies.good.power..Do.not.
skip.this.process.of.break-in..Failure.to.follow.this.
procedure.could.damage.your.new.engine..For.
further.details.on.breaking.in.your.engine,.please.
see.the.separate.Pro.Boat..18.instruction.manual.
Note:.It.is.common.for.an.ABC.
engine.to.go.through.a.glow.plug.or.
two.during.break.in.
Needle Settings
When.adjusting.the.settings,.always.adjust.the.
needles.in.small.increments,.about.1⁄16.of.a.full.
turn.at.a.time..Do.not.set.the.engine.too.lean,.
as.it.shortens.the.reliability.of.the.engine.
After.you.have.attained.the.correct.needle.
settings,.the.engine.will.have.a.strong.sounding,.
high-pitched.whine.at.full.speed,.and.a.thin.trail.of.
blue/white.smoke.will.come.from.the.exhaust.
Idle Adjustment
The.last.setting.to.set.is.the.idle.screw..To.obtain.
a.higher.idle,.turn.the.idle.screw.clockwise;.for.
lower.idle,.turn.the.idle.screw.counterclockwise.
Replacement Parts
In.the.event.that.you.need.to.replace.an.engine.part,.
there.is.a.complete.parts.listing.in.the.Pro.Boat..18..
instruction.manual..Exploded.views.will.help.you.to.
select.the.correct.parts.and.make.minor.repairs.
Head Shims
Several.head.shims.are.added.at.the.factory.to.
make.the.engine.easier.to.start.when.new..After.
break.in,.you.may.remove.all.but.one.of.these.
shims.to.increase.compression.and.power.
Maintenance
Lube.the.gears.inside.the.drive.with.waterproof.
grease.every.30.hours.of.use... . .
Check.all.screws.for.tightness.after.each.run.
