Axis Wake Research A20 - Before Starting the Engine; Inspect the Sea Strainer

BEFORE STARTING THE ENGINE
Raw water from the lake/river/sea is drawn into the boat to
cooltheengineanddrivetrain.Eveninclosedcoolingsystems,
it is necessary to circulate water in part of the system. To protect
the system, a sea strainer is installed near the raw water intake
and serves the purpose of keeping debris from entering the
cooling system and causing eventual engine failure. As with any
kind of strainer, it is necessary to regularly clean it so that water
canowunimpeded.
 Whenoperangtheboatin“dirty”waterthatisbrackish
orhasanoceabledegreeofweedsandotherora,itmay
be necessary to clean out the strainer in boats equipped with
seastrainersevenduringanoung.Paycloseaenonto
theenginetemperature,whichappearsonagauge.(Seethe
Instrument Panel and GaugesseconofthisOwner’sManual
formoreinformaon.)Anoverheangengineisprobablydueto
inadequatewaterow.
Continuing to operate a
boat that is overheating
the engine and drive train
will result in engine failure
eventually. Boat operators should routinely review
the engine temperature information provided on the
gauge on the instrument panel. Ignoring or failing to
take proper steps to reduce the engine temperature,
resulting in damage, is not covered under the warranty.
Leave the engine OFF.
To inspect the sea strainer, open the engine compartment. Note the sea strainer’s appearance as
shownintheaccompanyingphoto.Theseastrainerwillbelocatedindierentplaces,dependingonthe
boatmodel.(Ifyoucannotlocatetheseastrainer,askforassistancefromyourauthorizedAxisdealer.This
stepiscricalandcannotbeoverlooked.)
 Openandlithecovertoexposethelter.
 Removethelterandexamineforanydebristhathasaccumulatedwithinit.Whennecessary,clean
outthelterandthenreinstallitinthehousing.Handghtenthelidsothatwaterwillnotleakoutand
into the engine compartment.
 Ifitisnecessarytochecktheseastrainerduringanoung,turnOFFtheenginerstandthenclose
the valve on the water pickup feeding the sea strainer. Make sure you open the valve prior to running the
engine;otherwise,itwilloverheat.Whenevertheengineisrunning,waterisbeingdrawninandyouwill
not be able to inspect the sea strainer.
 Becausebaeriescontainuidthatiscauscandpotenallydangeroustoskinandbodyparts,boat
operatorsneedtoensurethatthebaeriesaresecurelyinplace.Also,iftheconneconsareloose,
erroneousreadingsmaybesenttotheboatsystem,whichcancauserunningandfunconalityproblems.
Toavoidbecomingstrandedduringanoung,itisimportanttohaveaccuratevoltagereadingsthroughout
theperiodofmetheboatisinuse.
 Tocheckthebaeries,besuretheengineisOFF.
 Locatethebaeries.Whiletheywillbeindierentplacesdependingontheboatmodel,usuallytheyare
found under the observer seat. Check your Quick Reference Guide in this Owner’s Manual to determine the
locaon.
 Ifthepostsshowsignsofcorrosionorotherdebris,removethebaeryandcleancarefully.Todoso,
