OH no.I used silicone, does the recommendation suggest that silicone will harm the transducer over time or just that it might break free easier.I will have one in epoxy for this year anyway, just hope the silicone will not destroy the one I attached with it.

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.

I did not have to be concerned because I have an old 1974 design and the under bottom is solid and thick.I think even a bubble in that, and I know there are some because there was one beside the hole I cut to do the through hull mount, which may have had something to do with why it was not always reliable so you always have to find a spot when there are no voids in the solid lay up too, but at least if it doesn't work you can move it fairly easily and you don't leave a gaping hole behind.

I seemed to remember that detail being part of past discussions on this subject.

Find a nice spot on the inside, close where you want it located, clean the area with solvent, let it dry and then apply a really generous gob of Dow Corning silicone sealant and submerge the active face of the transducer in it while holding on a slight angle to make sure you don't trap air bubbles, then press it down hard and hold there for a while. I did it that way based on information I got from this list because my Raymarine depth transducer was not reliable.it has worked flawlessly to over 200 feet (my boat draws about 6) for over 2 years and I have one less hole in the boat.I am happy Dwight Veinot C&C 35 MKII, Alianna Head of St. Margaret's Bay, NS
