ILMOR 2011 MV8 - Replacing the Raw Water Impeller;Sea Pump Impeller

• Rinseoffthefilterwithlow-pressurewater.Tapwaterisacceptable.Alwaysflush
fromthecleansidetothedirtside.Thisremovesthedirtanddoesnotdriveitinto
thefilter.
• Alwaysdrynaturally.Afterrinsing,shakeoffallexcesswaterandlettheelementair
dry.
Note: DO NOT use compressed air, open ame or heat dryers. Excess heat will shrink
the cotton lter media. Compressed air will blow holes in the element.
• Aftercleaningtheairfilteralwaysre-oilbeforeusing.SprayILMORairfilteroildown
intoeachpleatwithonepassperpleat.Waitten(10)minutesandre-oilanywhite
spotsstillshowing.Orusetheoilfromasqueezebottle,downintothebottomand
alongeachpleatwithjustonepassineachpleat.Lettheoilwickintothecottonfor
twenty(20)minutes.Re-oilanywhitespotsstillshowing.However,alsodonotover-
oilorsoakthefilter.
Note: Never use the air lter without oil. The lter will not stop the dirt without the
oil. Red dye is added to ILMOR air lter oil to assist in determining whether you
have complete coverage after application. Never use automatic transmission uid,
WD-40, LPS, other lightweight oils or anything not specied for this purpose.
• Re-install.Ensuretheelementseatsproperlybeforetighteningtheclampscrew.
 Because this process should be completed while the engine is cool (in order to avoid burns), it is
recommended that this check be completed prior to starting the engine. If checking during an outing,
allow the engine to cool. Be very careful to avoid burns from contact with hot engine parts.
• EnsuretheengineisOFFandtheenginesafetystartingswitchisdisconnected.
Leavethethrottle/shiftcontrolleverinneutral.Opentheenginecompart-
mentandlocatetherawwaterimpellerhousing.(Thisisalsosometimesre-
ferredtoasaseapump.)
• Disconnecttheintakeandoutflowhosesontherawwaterimpellerhousing.
Removeanydebrisfoundinsidethehosesandthenreconnect.
• Removetheserpentinebelt.
• Removethescrewsontheimpellercoverandverycarefullybreakthegasket
seal.Becauseagoodsealisveryimportanttoavoidpotentiallyseriousleaks
whiletheengineisinoperation,itisadvisabletohavesomenewgasketsinthe
boat’sgloveboxforsuchoccasions.Ifevenaslightgapexists,youmayexperi-
enceproblemsinthefuture.Therefore,replacingthegasketisabetteridea
thantakinganychanceswithanolderone.Also,leavinganyportionofthe
oldergasketonthehouseorcovercanimpedegoodcontact.
