Step 9:BeforeOperating YourBoat

Fill TheGasTank

Thecapacity ofthisgastankis900cc.Opentheblackcap

andcarefullyfillthetankwithyourgasoilmixture.Wipe

awayanyexcessgasthatmayhavespilledintotheboat.

Werecommendusing87or90octaneregularpumpgas.

Mixthatwith 100%synthetichighqualitytwostrokeoilat

aratioof25:1(4%ofoil). Agoodqualityoutboardengine

oil isadvisableasitcontainsanticorrosionadditives.

FillTheShaftLubrication OilCup

Your boatisfittedwithalubrication oilcupon the Tbar

thatsupportsthetopendoftheflexshaft.Itprovides

fulltimelubricationfortheshaftwhichisespecially

beneficialduringlonghighspeedruns.Fillthecupwitha

goodqualitylubricatingoil youcanusethesameoilthat

youusetomixthegas.

ConnectionCheck

Beforeyoustarttheengine,pleasecheckallconnections

andensuretheyarefullytightenedandsecured.Ifanyof

them areloose,itmightcausetheboattooperate

incorrectly.Inparticular,checktheenginemountbolts, the

rudderbladebolts, throttleandsteeringpushrod

connectors, thepropnut,exhaustboltsandtheclutch

systembolts.Beforerunningandbetweenruns,frequently

checkthattheflexshaftcolletistight otherwisetheshaft

couldflyoutofthecolletathigh enginerpm andcause

damage.

WaterCoolingLineCheck

Lackofcoolingwatercanquickly causetheengineto

overheatandbedamaged.Alwayswatchforleaksinthe

coolingsystem.Becomefamiliarwiththecoolingsystem

asshowninthefollowingdiagramandconfirm thatallthe

waterlinesarecorrectlyconnectedbeforestartingyour

engine.

Step 10:Starting the Engine

1:Startingtheengine

Before starting your engine, make sure that it is securely mounted in your boat with

appropriate fuel and exhaust systems. Read through all the following instructions before

starting.Ifyourradioisinstalledandyourthrottleservolinkedtotheengine,ensurethatthe

carburetor controls operate as explained in the “Carb Settings” section. If the engine is

connectedtoyourflexshaftdriveandpropeller,checkthattheyareproperlyalignedandthat

duecareistakentokeepeverythingwellclearoftheprop.Rememberthatthepropisvery

sharp,andalsothattheengineandexhaustwillgetquitehotwhenrunning.Donotrunthe

engineformorethanaminutewithoutasupplyofcoolingwater,andneverruntheengineat

morethanlowrevswiththeboatoutofthewater.

The 2012 sport version of Octane45 comes with an M39 ProMod barrel type racing

carburetorwhichdoesnothaveaprimerbulb,chokeorreturngaslinelikethemorecommon

WT644orWT711carbiesthatareusuallyfittedtostockZenoahorCYengines.TheM39

carb gives ultimate performance but does require a different starting procedure. Having

preparedyourengineandboatintheusualway(withfullregardtoallsafetyaspects),and

havingfilledyourfueltank,followthesestepsforeasystarting:

l Manuallychoketheenginebyblockingthecarbintakeventuri withyourthumborfinger

andslowlypullthestarterropeafewtimes.TheM39venturiismuchlargerthanother

carbies, so you may need to wear a glove for your thumb or finger to fully seal the

venturiforeffectivechokingoftheengine.

l Checkthatfuelisbeingsuckedalongthegaslineuptothecarb;continueslowlypulling

the starterrope until thegas line isclear orbubblesand you can feel fuelwetting your

thumborfinger.

l Removeyourthumborfingerfromthecarbandopenthethrottleabitlessthanhalfway.

l Slowlypullthestarterropeonemoretimetochecktheengineisnotflooded(seebelow).

l Smartlypullthestarterropeintheusualwayuntiltheenginestarts.

l BringthethrottlebacktoasteadyidleDONOTallowtheenginetooverrevasthiscan

causedamage.

Iftoomuchfuelissuckedintotheengineasyouchokeit,theenginewillbefloodedandwill

notstart.Itmaybehardertopulloveronthestarterastheexcessfuelincreasescompression.

Ifthishappens:

1. Removethesparkplugandcarefullywipedrytheelectrodeswithacleanragbefore

settingtheplugsafelyaside.

2. Holdthecleanrag justabovetheplugholeandpullthestarterropesmartlyafew

timestocleartheexcessfuel.

3. Reinstallthesparkplugandopenthethrottleabiglessthanhalfway.

4. Slowlypullthestarterrope tocheckthatcompressionisbacktonormal.

5. Smartlypullthestarterrope intheusualwayuntiltheenginestarts.

6. Bringthethrottlebacktoasteadyidle.

For“hotrestarts”youmaynotneedtochoketheengine.Checkthatthefuel lineisfullof

gaswithout any bubblesandsmartlypullthestarterrope.Iftheenginedoesn’tstartaftera

fewpulls,thenmanuallychoketheengineasaboveandslowlypullthestarterropeuntilyou

canfeelfuelwettingyourthumborfingerbeforeremovingitfromthecarbventuri.Slowly

pull the starter one more time to check the engine is clear, and then pull smartly until the

enginestarts.

2:Breakingin theengine

Toensurelonglifeandgoodperformancefromyourengine,youMUSTbreakitinproperly.

To obtain the optimum fuel for your engine, mix 87 or 90 Octane regular pump gas with

100% Synthetic Quality oil at a ratio of 16:1 (6% oil). Another choice for oil is quality

marine outboard engine oil. Operate your engine at about 1/2 to 3/4 maximum throttle

opening during the breakin process. DO NOT run at full throttle while breaking in your

engine. Patience is very important here;the boat will run more slowly during thebreakin

processandtheengine’soutputpowerwillincreasegraduallyoverthefirst34tanksoffuel.

Oncetheengineisbrokenin,thepowerwillincreasesubstantially.

3:CarbSettings

TheXP254McomeswithaM39ProModbarreltyperacingcarburetorasmentionedabove,

and the carb has been preset at the factory. However, it may require adjustment to

compensatefordifferentambientconditionssuchasvaryingtemperature,humidity,altitude,

etc.Thecarbhasthreeadjustments thelowandhighspeedneedlesandtheidlescrew.

#1: The LowSpeed Needle: The low speedneedleoftheM39carburetorishidden in the

center of the carburetor barrel. You need to use a small precision flat blade screwdriver to

adjustit.WhenadjustingtheLowSpeedNeedle,apply Loctite#222ontheneedlethreadin

ordertoholdtheneedleinpositionduringoperation.TheLowSpeedNeedleissetat661/2

turnsoutfrom fullyclosed(orfullyscrewedin).

Note:whentheM39carbisinstalledrotatedinyourboat,itisnoteasilytoadjustthelow

speed needle when you plan to make small adjustment to the low speed needle, you will

eitherneedtotakeoutyourenginefromyourboatoruninstallthecarbfromtheenginetodo

the little adjustable, however, once you set the low speed needle correctly, you will never

needtoadjustitagain,fromourtimelesstestingonourPromodM39carb,thelowspeed

needlesetto661/2turnoutwillworkwellonbothstockormodmotor.Andthecarbwas

Presetat6 turnoutfromourfactory.

#2: HighSpeed Needle: The HighSpeed Needle is set approximately 2 plus 1/2 turns out

fromfullyclosed.

#3:IdleScrew:SetthisatthelowestRPMwheretheengineidlesreliablewithoutstopping.

Screwingtheidlescrewinwillmakeyourenginerevfaster.

Note:Pleasetakeouttheidlescrewfromthecarbafteryoucompleteyourradiosetting.

4:Carburetor AdjustmentTips

When adjustingtheneedlesfromtheirstandardsettings,movethemonly1/8ofaturnatime.

Checktheresultsthenadjustfurtherasneeded.Neverattempttotunethehighspeedneedle

byrunningtheengineatfullthrottleoutofthewater!Thisisverydangerousanddamages

the engine. The following tips may assist in setting your carb for optimum engine

performance.

A:LowSpeedNeedle

Iftheengineiseasytostart,andidlesalittlerough(rich),andrespondswellwhenyouopen

the throttle with a brief show of smoke throughthe exhaust, then the low speed needle is

closetobeingcorrect.Iftheenginetendstohesitateorbogdownwhenyouopenthethrottle

quickly(especially whentheengine is cold), or ifthe idle speed is too highevenwith the

throttlebarrelnearlyclosed,thelowspeedneedleisprobablytoleanandyouneedtoscrew

itout(1/8ofaturnatatime).Iftheenginefloodseasilyandishardtostart,thelowspeed

needleisprobablysettorichandyouneedtoscrewitinslightly.

B:HighSpeedNeedle

When this needle is correctly set, the engine will run cleanly, accelerate well from half

throttle without hesitation, and will not lose RPMs during turns. It is tempting to lean the

highspeedneedletooptimizethemixtureforpeakpowerandonwaterRPM,butgoingtoo

leancanberiskyastheenginewillsufferfromoverheatingandreducedlubrication.Thiscan

leadtodamageorshorterlifeforyourengine.IftheenginestopsorlosesRPMswhenyour

boatisrunningonthewater,thehighspeedneedleisprobablysettooleanandyouneedto

screwitoutslightly.Iftheengineisnotrunningcleanlyandseemstohesitateornotreach

peakRPMs,thenthehighspeedneedleisprobablysettoorichandyouneedtoscrewit in

slightly.Runningwithaslightlyrichmixturemaycauseasmalldropintopspeed,butitwill

allowyourenginetoruncoolerandwithgoodlubricationforreliabilityandlonglife.

Step 11: LaunchingAndRunningYourBoat

*Beforethefirstruneachday:

a)Carefullycheckovertheboatasexplainedinpreviousstepstoensurenothingislooseandthatallthe

coolinglinesarecorrectlyattached.

b)Ifthereareotherradiocontrolmodelsinthevicinity,checkwiththeoperatorsthatyourradioisnot

onthesamefrequency.Ifitis,makearrangementstorunyourmodelsatdifferenttimes.Thisstepdoes

notapplyifyourradioisonthe2.4GHzbandasthisautomaticallyselectsanavailablefrequency.

c)Turnonyourradioandcheckthatit isoperatingcorrectly;carryoutarangecheckasexplained in

yourradioinstructionmanual.

d)CheckthatyourFailSafeisworkingcorrectly.

e)Lookaroundandensurethattheareawhereyouwillbeoperatingtheboatisclearandthereareno

people,otherboats(modelsorfullsize)ordebrisinthewater.

f)Studytheareawhereyouplantoputtheboatinthewaterandcheckthattherearenoobstructionsor

weed,andthatthewaterisdeepenough.

g)If otherRC boatsare running, especially ifit is an RCBoatClub area,find outany rulesabout in

whichdirectiontheboatsrun.Inmostcases,boatsruninaclockwisecircuit(ieturningtotheright).Do

notrunyourboatinadifferentdirectiontotheothers,andkeeptoanydefinedcircuit.

h)Ifotherpeopleareclosebywhereyouarestartingyourengine,makesuretheykeepclearoftheboat

especiallykeepthemwellawayfromtheprop.

i)ReviewallthesafetyproceduresmentionedatthestartofthisManual.

j)Makesureyouhavesomemethodofretrievingyourboatshoulditstoponthewaterforanyreason.

Never swimout to retrieve a boat. Somepeople have asmall inflatabledinghytheyuse as a "rescue

boat".Ifyourlakeorpondisnottoobig,youcanuseatennisballonalonglengthoflightline.Throw

theballoverthestalledboatandgentlypullonthelinetobringbacktheboat.Ifindoubtaboutrescue

methods,checkwithyourlocalRCBoatClub.

*Fillthegastankandstarttheengineasexplainedearlier.Waitafewsecondstoensuretheengineis

runningcorrectly.Momentarilyadvancethethrottleandcheckthattheclutchengagestospintheprop.

*Fittheenginehatchtotheboat,ensuringthelatchesaresecure.

*Whilstyoucanlaunchtheboatyourself,itisbesttohaveafriendtaketheboattothewaterwhileyou

hold the transmitter. If you do launch yourself, practice first without the engine running so you can

safelyputtheboatinthewater.Itmaybebesttofirstputthetransmitterinasafespotnearthewater's

edgebeforeputtingtheboatinthewater,ratherthanriskdroppingitwhilecarryingbothitandtheboat.

*Whencarryingtheboat,alwayswatchthatnothingisclosetothepropandthatyoukeepclearofother

people.

*Gentlyplacetheboatinthewaterwiththefrontpointingoutintoacleararea.

* If other RC boats are running, make sure they are well clear before slowly pulling the transmitter

triggerandacceleratingyourboatawayfromtheshore.

*Allowtheboattoriseonplanebutkeeptoaroundhalfthrottleandcheckthesteeringbyoperatingthe

rudder.

*Assoonasyoucan,whilstallowingforanyotherboatsorcircuitkeepingrequirements,bringyour

boatbackpastwhereyouarestandingandcheckthatwaterisflowingthroughbothoutlets.Getintothe

habitofcheckingforwaterfloweverytimetheboatgoespast.Weedordebrisinthewatercanblock

pickupsatanytimeandquicklycauseoverheatinganddamagetoyourengine.

* Enjoy running your boat, gradually increasing speeds (but remembering to properly breakin the

engine)andbecomingfamiliarwithhowyourboatturnsandhandlesindifferentwaterconditions.

*Whenyouareready,preparetobringyourboatbacktotheshore.Dothisbeforeyourenginerunsout

of fuel.Thegastankshouldgiveyouabout20minutesrunningtime.

*Checkthatotherboatsareclearbeforeyouleavetherunningcircuit,thensteerintotowardthebank

andbringtheenginebacktowardanidle.Iftheclutchdisengages,justopenthethrottleabitagainuntil

theboatmovestowardyoubutkeepatalowspeedsothatyoucaneasetheboatsafelynearthebank

beforeallowingittodrifttoastopbeforeithitstheshore.

*Stoptheenginebypushingthetrigger.

*Haveyourfriendpickuptheboatandbringitbacktothestand.Ifyoudothisyourself,firstputyour

transmitterdowninasafeplace.Rememberthattheengineandexhaustwillbehot,sobecarefulnotto

touchthemastheboatispickedup.

*Placetheboatbackonitsstand,removetheenginehatchandturnofftheradio.

*Allowtheengineandexhausttocoolbeforegettingclosetothem.

*Checktheinteriorofyourboattoseeifanywaterhascomeonboard;ifso,carefullyclearitaway.If

thereisa lotofwateronboard,findoutwhereitiscomingfromandcorrecttheproblem.Somewater

willusuallygetonboard,especiallywhenrunninginchoppyconditions.

*Generallycheckovertheboattoseethatnothinghascomeloose.

Step12: ProcedureShouldYourBoat FlipOver

* Sooner or later, all high speed RC boats will flip over. You should drive to suit the conditions to

minimisethechancesofthishappening,butit'salmostinevitablethatcircumstancesonedaywillresult

intheboatturningoverdespiteyourbesteffortstoavoidit.

*Retrievetheboatwithyourrescuemethod(inflatabledinghy,tennisballonalineorothermethod).

Note: Beawarethataflippedboat couldbefull of waterand consequently bevery heavy. Becareful

whenliftingitoutofthewater,andallowallthewatertodrainoutassoonaspossible.

*Holdtheboatverticallywiththebowupsothatanywaterdrainsoutoftheexhaustpipe.Thenputthe

boatbackonitsstand.

*Removetheenginehatchandgentlytrytopullthestartercord.It'squitelikelythatwaterwill have

enteredtheengineanditwillnotpullover.Donotforceit.Doingsocouldcausedamage.Iftheengine

doespullovereasily,seeifitwillrestart.Ifitdoes,allowittorunfor30secondsorso,thenresume

runningyourboatnormally.

*Iftheengineishardtopulloverorwillnotstart,removethesparkpluganddrytheelectrode.

*Withthesparkplugstillout,holdyourboatupsidedownandpullthestartercord10orsotimes.This

willexpelmostofthewaterfrom insidetheengine.(Note:Youmayneeda friendtohelpwiththis

althoughyoucandoitbyyourselfwithpractice.)

*Puttheboatbackonitsstand,reinstallthesparkplug,andgentlypullthestarterrope.

*Iftheengineisstillhardtopullover,orwillnotstart,repeattheabove3steps.

*Oncetheenginestarts,allowittoidlefor30secondsorsotocheckitisokay,thenstopit.

*Checkyourservoboxtoensurethatwaterdidnotgetinside,Ifitdid,stoprunningtheboatfortheday.

Cleanup the boat as usual(see the next Step) and take it home.Removeall theelectronics from the

servoboxandcheckthemforcorrectoperation.Ifthereisanyproblem,haveitfixedbyanexpert.

* If the servo box isdry, restarttheengine and relaunch the boat. Run it for 3to 5minutesat half

throttletoclearanyremainingwateroutofthebearings,thenresumenormalrunning.

Step13: AfterRunningYourBoat

* Attheend oftheday'srunning, wash all over theboat with freshwater. Washthehardware onthe

backoftheboat.Dryeverything,andthensprayallthehardwaregenerouslywithWD40orasimilar
