I have used silicon twice in the past for "temporary" testing in this
situation. (Figuring I would go back and fix it later once I found the
best spot). One was 4 years ago in my dingy and the other was 3 years
ago in my sportfish. Neither hull is cored. Both are still working
near perfectly for shallow water. (200ft) and high speed. I just cut
the caulking tube tip off at the widest point, made a pile of silicon
(no bubbles) and pushed the transducer down into the pile making sure
it was level to the world. I let it dry and tried it out. Since it
worked, I have not gone to back to "FIX" it... i have heard the evils of
doing this but I go back to the "if it ain't broke, don't fix it". I am
sure I am getting some attenuation but for what I am using them for
(SHallow water) I don't need all the power anyway. BTW... I do NOT
use this for my two 1500 ft sounders, those are thru hull with fairing
blocks, etc.


I, and lots of people I know have used clear silicone and it works
great.

Here's another tip: Don't swamp your boat with water as some idiot
suggested. The way to test for a good location is to simply fill a
zip-lock plastic sandwich bag with water and seal it closed. Place the
transducer on top of the water bag and move that around your DRY boat.
A breast implant can be substituted for the water filled baggie if you
have one handy.
