18 Transducers for Fishfinders
WARNING:
If the E66020, E66029 and E66043 thru-hull transducers are not
carefully installed and fitted to the shape of the hull, the vessel
may take on water. To ensure proper alignment and a secure fit,
these transducer models MUST be installed with a fairing. In
addition to improving fishfinder performance at all speeds, the
fairing allows better fitting to the hull and dramatically increases
the sealing surface.
Fairings are also strongly recommended for use with other high
performance transducers. See the table that follows.
The fairing is used to:
• Vertically orient the sound beam by mounting the transducer par-
allel to the water surface
• Minimize aerated water flowing over the transducer’s face by
mounting it in deeper water
• Reduce drag by directing the water around the multisensor
The fairing is made of high impact urethane with an integrated cutting
guide. It can be shaped to accommodate a deadrise angle of up to 25°
and a range of hull thicknesses as follows:
