• Runtheengineforatleastfifteen(15)minuteswhileinabodyofwater.Thisallows
forthecirculationoftheadditivesthroughoutthefuelsystem.
• Ifpossibleduringstorage,thetankventsshouldbesealed.Iftheventissealed,thetank
mustNOTbecompletelyfilled.Aninety-to-ninety-fivepercent(90-95%)filledtank
allowsroomforexpansion,whichwillberequiredatcertaintimeswhentempera-
turesincrease.Thehydrocarbonsingasolinereactwithnaturallyoccurringoxygen
andcreateaby-productknownas“gum.”Thesubstance,asthenameinfers,plugsup
fuelfiltersandinjectors.Sealingthetankhelpsreducegummingbysignificantlylimit-
ingtheamountofoxygenavailableforinteractionwiththehydrocarbons.
Completely lling the fuel tank prior to storage and then sealing the fuel
tank vent does not allow room for necessary expansion. This can result, in
extreme conditions, in fuel tank rupture. Such release of fuel into the boat
and potentially into the storage area could result in substantial damage to
the boat and contact with any spark (such as a ame-producing pilot light in
a heater) could also result in property damage and serious injury or death.

 Itisdesirabletokeepthefuel’stemperaturebelow80F.(26C.)Thegummingwill
increaseastemperaturesincrease.
 NotethatfuelstabilizersworkONLYinfreshgasoline.Stabilizerswillnotcureoxy-
genatedgasoline.Addingastabilizerwhentheboatisbeingpreparedforoutingsafter
storagewillNOTcleanthegummingthathasoccurredorremovewaterfromthefuel
tankorotherwiseeliminateanyproblemsthathaveoccurredduetofailuretoproperly
preparethefuelingsystemforstorage.
 ILMORsuggestsusingFederalorStateofCalifornia(TOPTIER)reformulatedgaso-
linewheneverpossibleasitstoresaswellorbetterthanconventionalgasoline.
 Even quality gasoline that has been properly prepared for storage should never
be stored for a period to exceed one (1) year.
Fuel systems on all boats equipped with ILMOR MV-8 engines MUST be
properly prepared for storage periods exceeding two (2) weeks, as outlined
in this Owner’s Manual. Failure to do so will void the warranty.
 Contaminantsinusedoilcancauseenginedamageduringstorage.Performan
oilchangeandrunenginetooperatingtemperaturetoallownewoilrecirculation.
 Cooling system storage/winterization requires draining and
flushingrawwatercomponentswithMarine/RVAntifreeze.Engineswithclosedcool-
ing systems using ILMOR 50/50 propylene glycol/water mix DO NOT REQUIRE
DRAINING.TheILMOR50/50coolantwillprovidefreezeprotectiondownto-26F.
(-32C.)Allcomponentswhichrawwaterflowsthroughmustbedrained.Thefollowing
stepsarerecommendedfordrainingofrawwatercomponents:
