It is not in the FAQ section, though we should link this one in there.
Make sure the area of install is a flat area that extends through the hull and is not a floor or support area. The transducer will only shoot properly through the hull.
Clean and prep the area on a flat location. This may need flattening and sanding, no oil can be present.
We suggest you use a 24 hour epoxy, and not a 5 minute version. There are limited fillers in this to have ping bounce and suppressing of the signal.
Get a small weight for the install to place on the transducer.
Aggressively sand the bottom of the transducer with a really heavy paper. Somewhere in the 80 grit range is suggested.
Mix the epoxy per the instructions.
Place it on the transducer in the hull for placement, if you can. Otherwise put it in a puddle in the hull area.
Flip the transdcuer and slowly press it into the epoxy against the hull.
Place the weight on top and wait till the epoxy cures.
That oughta’ do it other than running the wire.

This really is for those anal and wanting the best signal. You can take a paddle or wood boring bit the size of your puck, reduce the point size to about 1/4 to 3/16″ in length. Then you can take the bit and slowly eat a portion of the glass away from the top side and make a small pocket for the puck to sit in. Do this slowly to make sure and only have the outer area watched while you drill to verify the small point protrudes and you do not over cut the area. Then repeat steps listed above on the epoxy and install. This reduces the glass thickness in the center of the boat for a better reading and less interference or cushion of the signal strength.
