Recommended Tools and supplies 
If you prefer the option of routing the cable through the transom, you 
will need a 5/8" drill bit. Each transom mount requires use of a high 
quality, marine grade above- or below-waterline caulking compound.  
NOTE: 

The following installation types also call for these recommended 
tools and required supplies (supplies are not included): 

Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-

head screwdriver (for mounting screws and their pilot holes). Supplies: 

none. 

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. Supplies: 100 grit sandpaper, specially for-

mulated 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. 
NOTE: 

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
