 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discon-
nected.Leavethethrottle/shiftcontrolleverinneutral.Opentheengine
compartmentandlocatetherawwaterimpellerhousing.(Thisisalsosome-
timesreferredtoasaseapump.)
• Disconnecttheintakeandoutflowhosesontherawwaterimpellerhous-
ing.Removeanydebrisfoundinsidethehosesandthenreconnect.
• 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
experience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.
Ignoring elevated temperatures on a temperature gauge or any other evidence of the en-
gine operating at temperatures above recommended levels can result in serious damage
to the engine. Any resulting damage will not be covered by the warranty.
• Inspecttheinsideoftheimpellerhousing.Ifanyrubberextrusionsonthe
endofthearmappearfrayedorworn,itshouldbereplaced.Debrisenter-
ingtheimpellerinevitablywilldamageit.However,theimpellerservesits
purposeindeflectingdebrisandkeepingitoutofmuchmoreexpensive
internalengineparts.
•Anyuncertaintyabouttheconditionoftheimpellermeansthatitshould
beremovedandinspected.Theimpellerfitsverysnuglyandwillrequire
somecareinremovingandre-installingorinstallinganewone.Thisen-
suresproperoperation.Theuseofsoaporwater-basedpetroleumjellywill
helpwithinstallation.Notethatproperplacementonthegearresultsina
squeezeonthearms.Thisisthecorrectinstallation.
• Placeagasketbetweenthehousingandthecoverafterensuringthatthe
surfacesaresmoothandclean.Re-installthescrewsloosenedwhentheface
platewasremovedearlier.Donotover-tightenthebrassscrewsasitwill
causethemtobreak.
