I've been told the same thing about silicone under the transducer, I didn't do that.
Between the transducer and the hull is ultrasound gel. It's designed specifically to act as a high grade interface between a sonar transducer and another surface (afterall the sounders, fish finders and bottom plotters we use are just lower grade and lower frequency versions of the same things neonatal doctors use when a women goes in for a pregnancy checkup).
I used 3M 4000 sealant / adhesive only around the outside edge of the transducer to Dam the gel underneath the transducer and prevent it from leaking out, while also holding the transducer in place.
So far it's worked incrediblly well. I have actually seen the box shape of a lobster pot show up on the sonar display when I got a little too close to a bouy once, as well as the line going up to the surface bouy.
It also has the significant benefit of being easily removable should the transducer fail and need replacing for any reason in the future...
We'll see how well it works after sitting for the winter and the gel freezes... Worst case I go to the trusty old epoxy meathod next spring
