ILMOR 2011 MV8 - Clean the Engine Flame Arrestor;Air Filter

Note: Access to the transmission uid lters is somewhat difcult in the conned
space in some models. Nonetheless, this maintenance is vital to long, trouble-free
use of the transmission. That is why it is recommended that this service be performed
by an authorized ILMOR dealer.

ILMOR recommends that the ame arrestorbeinspected
andcleanedorreplacedevery100hoursorannually,whichevercomesfirst.Ideally,
thisshouldbedoneatthebeginningoftheboatingseason.Duringstorage,material
maycollectinsidetheflamearrestorhousing,whetherairborneorleft by
smallcreatures.
 Itisextremelyimportanttotakecarethatwhileremoving,replacingandwhile
theflamearrestorisofftheengineabsolutelynothingforeignenterstheengine
throughtheareanormallycoveredbytheflamearrestor.Anymaterialsentering
cancausedamagetoyourengineandwillvoidthewarranty.
 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.
 TheMV8engineisequippedwithaU.S.CoastGuard-approvedflamearrestor,
whichisanILMORspecificairfilter.TheairfilterconformstoSAEJ1928andISO
13592,whicharespecialflamearrestorstandards.Therefore,otherfilterscannot
beusedasreplacements.
 Thepurposeoftheflamearrestoristocontainanybackfirethatmayoccur
duringengineoperation.Thiswasamuchbiggerissueinolder,carbureteden-
gines.Itisuncommoninelectronic,fuel-injectedengines,butitispossibleand
mustbeaddressed.
 The air filter for the MV8 engine is 94PE01163.
•EnsuretheengineisOFFandtheenginesafetystartingswitchisdisconnected.

•Carefullyremovetheflamearrestorfromtheengine,usingascrewdriveronthe
clampscrew.Takecarethatnoforeignobjects,includingdust,enterstheengine

•Taptheelementtodislodgeanylargeembeddeddirtandthengentlybrushwith
asoftbristlebrush.
