18 Transducers for Fishfinders
WARNING:
Ifthe E66020,E66029 and E66043thru-hulltransducersare not
carefully installed and fitted to the shape of the hull, the vessel
may takeon water.Toensure proper alignmentand a securefit,
these transducer models MUST be installed with a fairing. In
addition to improvingfishfinderperformance at allspeeds, the
fairingallowsbetterfittingtothehullanddramaticallyincreases
the sealing surface.
Fairingsare also strongly recommended for usewith other high
performance transducers. See the table that follows.
The fairing is used to:
• Verticallyorient the sound beam by mounting the transducer par-
allel to the water surface
• Minimize aerated water flowingover the transducer’sfaceby
mounting it in deeper water
• Reduce dragby directing the water around the multisensor
