I have mounted depth finder pucks in the bilge two different ways, and both worked for me. First time we cut a piece of pvc pipe at the bottom angle about four inches long and used silicone to glue it to the hull bottom. We filled this with water and put the puck in this "well" secured so it was vertical. It worked fine. Second time I just siliconed the puck to the bottom of the hull, and it also worked fine. Used silicone in case I wanted to move it.Put silicone all over the puck, and kind of squish it in place so no air bubbles. Should be over a place in the hull that has no voids or contains foam.
