Theflowoffreshwaterintoandoutoftheengine'scoolingsystemisregulatedbythe
thermostat.
19:03BOTHFRESHANDSEAWATERSYSTEMS
:Wateriscirculatedthroughtheengineand
theheatexchangedbyawaterpumpwithneoprenerubberimpellers.Thenatureofthese
impellersrequiresthattheyneverberundry.Aspareimpellerandimpellercovergasket
shouldalwaysbekeptonboard.Refertoengineowner'smanualfortype,locationand
replacementprocedures.
Routinelychecktheexhaustportatthetransomtoseeifwaterisbeingexpelledand
insurethatcoolingwaterisbeingcirculatedthroughthesystem.Itisespecially
importanttocheckafteranimpellerhasbeenchangedorotherengineworkhasbeendone.
19:00ENGINECOOLINGANDEXHAUSTSYSTEMS(Cont'd)
19:04ENGINEBACKFIRE:Theexhaustsystemasaunitisconstructedofpartsdesigned
towithstandinternalpressureseveraltimesgreaterthanthatwhichisexpectedina
normallyoperatingwetexhaustsystem.However,enginebackfiresarecapableofvery
highinstantaneouspressureswhichmayexceedthesystem'scapacity.Therefore,ifa
backfireoccurs,theentireexhaustsystemshouldbeexaminedthoroughlyforanyresultant
damage.
19:05HOTWATERHEATERS
:(Option)Hotwaterheatersutilizingtheengine'shotwater
asasourceofheat,tapintothecoolingsystemasthewaterleavestheengineatits
hottestpoint.Itthencirculatesthroughthewaterheaterwhereaheatexchangerheats
thedomestichotwater.(RefertoI30)
19:06WINTERIZING
:Theengineandexhaustsystemrequirespecialattentionwhen
preparingforwinterstorage.(RefertoSection30:00forcompletewinterizingdetails)
20:00ELECTRICALSYSTEM12VOLTDC
Wiringforthe12voltsystemhasbeenruninaccordancewithindustrystandardsand
qualitywireandconnectorshavebeenusedthroughout.Asaltairenvironmentand
continualboatvibrationsrequirethatwiresandterminalsbecheckedroutinelyfor
corrosionorwear.
20:01BATTERYSWITCH
:Amasterbatteryswitchlocatedonthegalleyfacecompletely
controlstheflowofpoweroutofthebatteries.Systemswithtwobatterieshaveswitches
forselectingeachbatteryseparatelyorbothbatteriestogether.Systemswithone
batteryhaveswitcheswithonoroffposition.
CAUTION
:DONOTSHUTOFFTHEBATTERYSWITCHWHILETHEENGINEISRUNNINGORSERIOUS
ALTERNATORDAMAGEWILLRESULT.
20:02BATTERIES
:Batteriesarelocatedunderthequarterberthindurableand
corrosionresistantcases.
Itisimportanttokeepbatteriesfullychargedatalltimes.Lowbatteriesmayeffect
thefunctionoftheradio,depthsounderandotherelectronics.
Chargebatteriesseparatelywhenchargingwiththeengine'salternator.Donotattemptto
chargedeadorextremelylowbatterieswiththealternator.Thebatteriesshouldbe
chargedoutoftheboat.Batteriesshouldalsoberemovedforwinterstorage.
Inspectmonthlyandkeepbatterycableterminalscleanatalltimes.Athoroughcleaning
shouldbedoneyearlyusingastiffbrushandasolutionofbakingsodaandwater.After
cleaning,applyalightlayerofpetroleumjellytocableterminalstoretardcorrosion.
Checkfluidlevelineachbatterycellonceeachmonth.Iflow,addwatertoabout1/2"
abovethetopoftheplates.Donotoverfill,andneveraddanythingtofluidexcept
clean,freshwater.Usedistilledwaterifavailable.
