Maintenance
If yourboat remains inthe water forlong periods of time, algaeand other
m
arine growthcan reduce theeffectiveness of the transducer. Periodically
cleanthe faceof thetransducerwith hotwater.
If yourboat remains out ofthe water fora long periodof time, itmay take
some timeto wet thetransducer afterit is returnedto the water.Small air
bubblescan cling tothe surfaceof the transducer andinterfere withproper
operation.These bubbleswill dissipatewithtime, oryou maywipe thefaceof
thetransducer withyourfingers afterthetransducer isin thewater.

8. Handtighten thenut ONLYuntil theassemblyis firmlyseated, then tightenNO MOREthan 1/8of aturn extra.
CAUTION:To avoiddamage, donotovertighten thenut.
Remove the excessadhesive sealant from the outside of the hull to ensure smooth waterflow over the
transducer.
4. Routingthe Cable
Thetransducer cablemust berouted tothe pointwhere thecontrolhead ismounted.
NOTE:Your boatmayhave apre-existingwiringchannel orconduitthat youcanuse forthe transducercable.
1. Unplugthe otherend ofthe transducercable fromthe controlhead.
CAUTION!Do notcut orshorten thetransducercable, andtry notto damage thecable insulation.Route thecable asfar
aspossible fromany VHFradio antennacablesor tachometercablesto reducethe possibilityof interference.If thecable is
too short, extension cables are available toextend thetransducer cableup to atotal of 50'.For assistance,contact the
CustomerResourceCenter atwww.humminbird.comorcall 1-800-633-1468for moreinformation.
2. Route and secure the cable, avoiding areaswhere it may be damaged or interfere with normal boating
operations.
5. Connecting the Cable
Insert the transducercable into the appropriate terminalslot. The cable connectors arelabeled, and there are
correspondinglabels on thecable holder onthe rear ofthe control head. Theslots are keyedto prevent reversed
installation,so becarefulnot toforcethe connectorinto theholder.
Yourcontrol headisnow readyfor operation.

3. Attachingthe Transducer
Beforeattaching yourtransducer, youwillneed todecide whichtype ofinstallationto use:
• For a standard installation,where thereare nomajor obstructions and thedeadriseis less than 8degrees, use
theincluded levelingblock (uncut),andmount itinside thehull.Drill thehole perpendicularto thehull.
• For aninstallation thatneeds tominimizethe impactof asmall obstruction,but wherethe deadriseis lessthan
8 degrees,use theincluded levelingblock (uncut),and mountit outsidethe hull.Drill thehole perpendicularto
thehull.
• For an installationwhere the deadriseis greater than8 degrees, usethe included leveling block,cut at the
appropriateangle,to compensatefor thedeadrise. Drillthehole perpendicularto thewaterline.
1. Fromthe outsideof thehull,drill asmall pilothole(smaller thanthe centeringbit ofyour drillbitor holesaw), at
themounting locationyou selectedin procedure2.
CAUTION: Before youdrill, makesure you aredrilling inthe correct orientation accordingto theinstallation guidelines
above.
2. Use thepilot hole(from the outsideof the hull) todrill a 11/8" hole thatis sized to fitthe threaded stem of
thetransducer:
NOTE:For installationswhere thedeadrise islessthan 8degrees, whereyouwill notbe cuttingthe levelingblock, drillthe
holeperpendicularto thehull.
NOTE:For installationswhere thedeadriseis greaterthan 8degrees,and youwillbe cuttingthe levelingblock atan angle,
drillthe holeperpendiculartothe waterline.
3. Thoroughlyclean anddeburrthe drilledhole andclean theoutsideof thehull.
4a. Ifthe deadriseis lessthan 8degrees, youwill notbe cuttingthe levelingblock; install it either onthe inside of
thehull (standardinstallation)or onthe outsideof thehull tocompensatefor smallobstructions.
OR...
4b. Ifthe hullangleis greaterthan8 degrees,youshould cutthe includedleveling blockand useboth piecesto level
thetransducer.The blockshouldbe cutto matchthe angleofthe deadriseofthe hull.Theleveling blockincluded
withyour transducercan accommodatea maximumdeadrise angleof 25degrees.
CAUTION:Use onlythe levelingblock includedwith thistransducer. DoNOT usea woodenleveling block,as anyswelling
ofthe woodmightcause theplasticon thetransducerto shatter.
NOTE: Replacementleveling blocksare availablefrom Humminbird®.For assistance, contact theHumminbird® Customer
ResourceCenter atwww.humminbird.comorcall 1-800-633-1468.
NOTE:You shouldcut thelevelingblock intotwo equalpieces:one whichmounts outsidethe hulland isshaped tomatch
the profile ofthe transducer,and onewhich mounts inside thehull andprovides a level surface forthe fasteners. The
thinnestwall oftheoutside levelingblock mustbe atleast 1/8".
NOTE:A separately-purchased fairing block can also beused tocreate ahydrodynamic waterflow around the transducer
body.The designand fabricationof thisblock variesgreatly withdifferenthull shapes;therefore,it shouldbecustomized by
aqualified marinetechnician.
5. Feedthe cablethrough thehole, then temporarilyinstall thetransducerto checkthe fit.
6. Applya generousamountof marine-gradesilicone sealantorslow-curing epoxyinside thedrilledhole andalong
the matingsurfaces ofthe transducerhousing. Sealthe matingedgesof theleveling blockas well.
7. Makesure thatthe narrow(thin)end ofthe transduceris pointingforward. Insertthe transducerinto thedrilled
holefrom outsidethe boat,then installthe nutonto thethreaded stem from insidethe boat.
NOTE:This typeof transduceris directionalin natureand mustbealigned withthe frontof theboat (thedirectionof travel)
andparallel tothe centerline. Failureto alignthe transducerproperlywill resultin incorrect bottomreadingsand incorrect
fishlocations. (Seeillustrationfor orientation).
