1.1 Introduction

Thishandbookprovides instructions to assist you intheinstallation
andset up of thevarioustransducers for Raymarine fishfinders.See
Table 1-1 on page4for a list ofthe different sensor,material and
mountingtypes available.

General

Raymarinefishfindersrequire a transducer,either thru-hull, in-hull,
ortransom-mount.

Transducerscan measure water depth,temperature, distance
traveled,and/or speed. It is important to position yourtransducer
correctly,as described in Section 1.4,Selectingthe Equipment
Location.

Note:If speed andtemperaturearebeing input via SeaTalk, these

valuesare displayed instead of thespeed and temperature inputs
from the transducer.

EMC Installation Guidelines

All Raymarine equipment and accessoriesare designed tothebest
industrystandardsfor use in the leisuremarineenvironment.

Theirdesign and manufactureconformsto the appropriate
Electromagnetic Compatibility (EMC) standards, but correct
installationis required to ensure thatperformanceis not
compromised.Althoughevery effort has been takentoensure that
theywill perform under all conditions,itisimportant to understand
whatfactors could affect the operationofthe product.

TheguidelinesgivenheredescribetheconditionsforoptimumEMC
performance,but it is recognizedthatit may not bepossibleto meet
allof these conditions in allsituations.Toensure the bestpossible
conditionsforEMC performance within theconstraintsimposed by
any location, always ensure themaximumseparationpossible
betweendifferent items of electricalequipment.

For optimum EMC performance, itis recommended that wherever
possible:

• Raymarineequipmentandcables connected toit are:

• Atleast1 m (3 ft)from any equipment transmitting or cables

carrying radio signals, e.g., VHFradios, cables and antennas.
In the case ofSSBradios, the distanceshould be increasedto
2 m(7 ft).

• Morethan 2m (7 ft) fromthe path of a radarbeam. A radar
beamcan normally be assumedtospread 20 degrees above
andbelowtheradiatingelement.

• Theequipment issuppliedfroma separate battery from thatused
forengine start. Voltage drops below 10 V (20Vfor 10 kW open
arrayscanners) in the power supplytoour products, and starter
motortransients,can cause theequipmenttoreset. This will not
damagethe equipment, but may causetheloss of some informa­tionand may change theoperating mode.

• Raymarinespecifiedcables are used atall times. Cuttingand
rejoiningthesecablescancompromiseEMCperformanceandso
mustbe avoided unless doing soisdetailedin the documentation.

• Ifasuppressionferriteis attachedtoacable,this ferriteshouldnot
beremoved. If the ferrite needstoberemoved during installation
itmust be reassembled in thesameposition.

Chapter 1: Overview 3

Thefollowingillustrationshows a typical range ofsuppression
ferrites fitted to Raymarine equipment.

Connections to Other Equipment

Ifyour Raymarine equipment is tobe connected to other equipment
usinga cablenotsuppliedbyRaymarine,asuppressionferriteMUST
always be attached tothe cable nearto the Raymarine unit.

1.2 The Fishfinder System

Transducersenablefishfinders to displaydepth, water temperature
and/orspeed, depending on thetypeof transducer(s) installed.

Beforeyou start the installation, check thatyouhave the correct
transducerfor your application, as described belowin Selecting the
CorrectTypeofTransducer.

WARNING:

IftheE66020,E66029 and E66043 thru-hull transducers are not
carefully installedand fitted to theshape of the hull, thevessel
maytake on water. Toensureproper alignment anda secure fit,
these transducermodels MUSTbe installed with afairing. In
additionto improving fishfinderperformance atallspeeds, the
fairingallowsbetterfittingto the hullanddramaticallyincreases

Applicatio ns

Plastichousingsare recommended for fiberglassor metalhulls.
Bronze housings arerecommendedfor wood or fiberglasshulls.

• Installa tionof a bronze housing in a metal hull requiresusing of a
fairing,available from your Raymarine dealer .

• Neverinstallametal housing in a vesselwitha positive ground
system.

Transom Mount Transducersare recommended for personal
watercraftand powerboats with outboard, inboard-outboard and jet
drives.They are NOT recommendedforlargeor twin screw inboard
boats.

• Adjuststo transomanglesfrom 3° – 16°.Forangles greater than
16

°, a tapered plastic, wood or metal shim will be needed.

• Designedfor operation from5–58 m.p.h. (4 – 50knots).

Thru-HullTransducersare recommended for boatswithstraight­shaftinboard engines.

In-Hull transducers arerecommendedforfiberglasshulls,especially
inhigh speed power boatsandracingsailboats.

Planning the Installation

Beforeyou install your system, plan theinstallation,considering:

• Locationof thetransducerand fishfinder,as described in

Section 1.4

• CableRuns,includingcablesforanintegratedsystem(to provide
heading and position data,etc.), as described inSection 1.5.

1.3 Unpacking and Inspecting the Components

Unpackyour system carefully,toprevent damage to theequipment.
Savethe carton and packing,in case you needtoreturn a unit for
service.

Checkthat you have allthe correct system components. These
dependon your system package, asfollows:

Itis very important thatyoumount the transducer correctly.The
transducerprovidesthe most reliable readings ifitlooksinto water
thatis smooth and undisturbed.

Chapter 1: Overview 7

Acousticnoiseisalwayspresentandthesesoundwavescaninterfere
withthe operation of the transducer .Ambient (background) noise
fromsources such aswaves, fish, rainand other vessels cannotbe
controlled.Carefully selecting thetransducer’smounting location
can minimize noise generated by the vessel’spropeller(s), shaft(s),
machinery, andotherecho sounders. The lowerthe noise level, the
higherthe echo soundergainthat can be used,andthe better the
Fishfinder’sperformance.

CAUTION:

To ensureaccurate readings,DO NOT mount the transducerin
anareaof turbulence or bubbles:

• near waterintakeor discharge openings

• behindstrakes, fittings orhullirregularities

• behinderoding paint(an indication of turbulence)

Choosea location where:

• Thewaterflowingacrossthehullissmoothestwitha minimumof
turbulenceand bubbles (especially at highspeeds).

• Thetransducer willbecontinuously covered by waterwhen the
boatis moving. If thetransduceris mounted near the sideofthe
boat,it may be exposedwhenthe boat is turning.

• Thetransducer beamis unobstructed by the keelorpropeller
shaft.

• Thereis aminimum deadrise angle.

• Thereis adequate headroom inside the vessel for the height of the

thru-hullhousing,tighteningthenuts, and removing the valve
assembly insert.

• Twin drive boat- If yourboathas twin propellers (outboard or
inboard-outboard),mount the transducerbetween thedrivesnear
the centerline of the boat. If the boat will be operated at high
speeds,thetransducermay be mounted closer to thecenterlineof
the hull.

• Planin ghull powerboat–Mountwell aft, on or nearthe center-

that it is in contactwiththe water at high speeds.Mounton the

OutboardandI/O – Mount just forwardofthe engine(s).
Inboard–mount well forward ofthepropeller(s)andshaft(s).
Step-hull – Mount just aheadofthe first step.
Boatscapableof speeds above 25kn(29 m.p.h.) – Review

transducer location and operating results of similar boats before
proceeding.

• Finkeelsailboats– Mount to theside of the centerlineand for-

wardof the fin keel1- 2 ft (300-600mm).

• Fullkeelsailboats–Locate amidships and away from the keel at

thepoint of minimum deadrise angle.

• FiberglassHulls – Since thehullabsorbs acoustic energy,trans-

mittingthroughthe hull reduces the sensor’sperformance. Fiber­glasshullsare often reinforcedinplacesforadded strength.These
coredareascontain balsa woodorstructuralfoam,which are poor
