 Proper storage and/or winterization preparationsareasimpor-
tantashowadrivetrainismaintainedinuse.Sincespecialpreparationsarenecessary,the
boatownershouldhavetheworkdonebyanILMOR-authorizeddealer.Damagethatoc-
cursfromimproperstorageand/orwinterizationisnotcoveredunderwarrantyandmust
beavoided.
 Enginewinterizationrequiresaddingafuelstabilizerandbiocidetothefueltank/sys-
tem,changingtheengineoil/filter,drainingallrawwaterfromthecoolingsystem,and
addingmarine/RVanti-freezetoallrawwaterenginecomponents.
 Damage due to improper storage and/or winterization preparations is not cov-
ered under warranty. Owners are encouraged to seek assistance from an authorized
ILMOR dealer to properly prepare the drive train for periods of inactivity exceeding
two (2) weeks.
 This preparation needs to be done prior to removing water from the engine, if that will be part of
the process.
 Boats that are going to be storedforextended
periods(morethantwo[2]weeks)orwinterizedshouldhaveatten-
tionforthefuelsystem.EvenTOPTIERgasolineswillexperience
someseparationofelementsandsettlingduringtheseperiods.Of
considerableconcernisthatwatercondensationwilloccurwithin
thefuelsystem,andwaterisanenemyofgood-startingandrunning
enginefuelsystems.Therefore,followthisprocedure:
•Thefueltankshouldbeninety-to-ninety-fivepercent(90-95%)
fullofTOPTIERgasoline.Thisallowsforminimalroominwhich
aircanoxygenatethefuelduringdiurnalcycles(dailyperiodsof
expansion/contractionofgasolinevaporsandairasaresultoftem-
peraturechanges).Astemperaturesriseinthetank,thepressure
alsorise, pushingoutgasoline vapor-and-airmixtures.Whenthe
temperaturefalls,pressurelowersandthesystemwillseektodrawfreshairandwatervapor
(dependingonthehumiditylevel)intothetank.Freshairisreplacedwith“lightends,”which
arelow-boilingcomponentsthatvaporizeatambienttemperatures.Lightendsarerequired
duringcoldstartstovaporizethefuel.Sincethedailydiurnalcycleseliminatethelightends,
anearlyfulltankhelpstominimizetheairvolumeenteringthesystem.
