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):
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-
head screwdriver. Supplies: none.
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit,
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood screws.
Tools: two adjustable wrenches,
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.
