Recommended Tools And Supplies; Single-Frequency Transom Installations; Dual-Frequency Transom Installations; Single-Frequency Trolling Motor Installations - Eagle FishElite 642c Installation And Operation Instructions Manual

Read these instructions carefully before attempting the installation.
Determine which of the installation methods is right for your boat.
Remember, transducer location is the most critical part of a so-
nar installation.

Recommended Tools and Supplies

If you prefer the option of routing the cable through the transom, you
will need a 5/8" drill bit. (If you intend to install an additional speed or
temp sensor and route its cable through the same hole in the transom,
you will need a 1" (25.4 mm) drill bit to accommodate all the cables.)
NOTE:
The following installation types also call for these recommended
tools and required supplies that you must provide (supplies listed
here are not included):

Single-frequency transom installations

Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-
head screwdriver. Supplies: none.

Dual-frequency transom installations

Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood
screws.

Single-frequency trolling motor installations

Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic
cable ties.

Shoot-through hull installations

Tools: these will vary depending on your hull's composition. Consult
your boat dealer or manufacturer. Other tools are a wooden craft stick
or similar tool for stirring and applying epoxy, and a paper plate or
piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100
grit sandpaper, specially formulated epoxy adhesive available from LEI
(see ordering information on the inside portion of the back cover). A
sandwich hull also requires polyester resin.

Selecting a Transducer Location

1. The location must be in the water at all times, at all operating speeds.
2. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is not placed in a smooth flow of
water, interference caused by bubbles and turbulence will show on the
sonar's display in the form of random lines or dots whenever the boat is
moving.
