Planning The Installation - Raymarine Transducers User Manual

Chapter 1: Overview

Planning the Installation

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.
Applications
Plastic housings are recommended for fiberglass or metal hulls.
Bronze housings are recommended for wood or fiberglass hulls.
• Installation of a bronze housing in a metal hull requires using of a
fairing, available from your Raymarine dealer.
• Never install a metal housing in a vessel with a positive ground
system.
Transom Mount Transducers are recommended for personal
watercraft and powerboats with outboard, inboard-outboard and jet
drives. They are NOT recommended for large or twin screw inboard
boats.
• Adjusts to transom angles from 3
16 , a tapered plastic, wood or metal shim will be needed.
°
• Designed for operation from 5 –58 m.p.h. (4 – 50 knots).
Thru-Hull Transducers are recommended for boats with straight-
shaft inboard engines.
In-Hull transducers are recommended for fiberglass hulls, especially
in high speed power boats and racing sailboats.
Before you install your system, plan the installation, considering:
• Location of the transducer and fishfinder, as described in
Section 1.4
• Cable Runs, including cables for an integrated system (to provide
heading and position data, etc.), as described in Section 1.5.
