I wondered if you could take a broken puck transducer and epoxy it into a pvc fitting(or piece thereof) already having the clamp in place. This would remove from the clamp on 2 small plastic sections and spread it out over a larger, more stable area. As long as you didn't put the puck way up inside it shouldn't effect the operation of the signal. What do you think, Cane Pole? You understand this area more than the rest of us. Just some input.
