NOTE: A properly mounted serpentine belt shouldhavea
smallamountof“play.”Withoutasmallamountofplay,thebeltwillwearoutwell
earlierthanshouldbeexpected.Toomuchplaywillallowthebelttocomeoffthepul-
leysystem.Pressyourthumbagainstthebeltatseverallocationsalongtheserpentine
route.Thebeltshouldgivenomoreorlessthan1/8”to1/4”.Whenthebeltisoff,at-
tentionshouldalsobegiventothequalityofwearofthegroovesontheundersideof
thebeltwhereitmakescontactwiththepulleys.Ifyouareunsureofthewearpattern,
checkagainstanewbelt.Ifthereisanyuncertainty,seekassistancefromyourauthorized
ILMORdealer.Ifthebeltistoolooseandcomesoffortootightandwearsthrough,it
willcausetheelectricalsystemtomalfunction.Thiscouldoccurduringanoutingand
strandtheboaters.Therefore,takethismaintenancefunctionveryseriously.
• Theserpentinebeltislocatedonthefrontoftheengine,exceptinV-drive

• Removetheserpentinebeltbyunwrappingitfromeachofthepulleys.
• Checkthewearontheinsidegrooves.Ifthisispartoftheannualmaintenance,
mostlikelytheserpentinebeltwillneedtobereplaced.
• Toinstallanewbeltortoreinstalltheexistingbelt,wrapthebeltaroundthepulleys
asshown,andusea15mmsockettorotatethetensionertoitsmaximumtravel.This
shouldallowenoughslacktoslidethebeltoverthesmooth,waterpumppulley.
• Easethetensionerbackintoplaceandensurethatthebeltisproperlywrapped
aroundallofthepulleys.
