Read these instructions carefully before attempting the installation. 

Determine which of the mounting positions is right for your boat. Re-

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: high quality, marine grade above- or below-

waterline sealant/adhesive compound. 

Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head 

screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood 
screws,  high quality, marine grade above- or below-waterline seal-

ant/adhesive compound. 

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

cable ties. 

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 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. 

Some aluminum boats with strakes or ribs on the outside of the 

hull create large amounts of turbulence at high speed. These boats 

typically have large outboard motors capable of propelling the boat
