If going in-hull, you can test your location while in the water by placing a baggie of water between the transducer and the hull. If it works like that, it will work glued down. *This does not work if the boat is out of the water*. I shouldn't have to say that, but I will because I have had a couple of people do just that.
FWIW, the transducer maker, Airmar, recommends epoxy, and specifically warns against silicone.
