I have the same unit on my Cal 20, but didn't mount it in silicone.

I mounted a PVC tube with a diameter of the same size as the
transducer, sealed the bottom with glass, then filled the tube
with mineral oil. I mounted the transducer on the bottom of a
plug that fits inside the tube. The oil keeps the signal good,
and if I need to replace the transducer, I don't have to break
it off the boat.

Id did something similar I epoxyed it to the hull. Goes right thru
the steel without a problem, The mfg told me to just make sure you
have no bubbles in the epoxy. The only minus is that when you heel you
do not get a good picture. I have a keel board box that prevents me
from mounting it horizonal. Port tack picture is excellent, stbd not
so good.

But hey It works good at seeing the bottom and fish.

It does speed, temp and depth, but the bronze thru hull protrudes from the hull
with the fairing block and that sort of bugs me. It's a great deal though...

I have a Humminbird fishfinder on my boat. I mounted the transducer
inside in a bed of clear silicone against the bottom of the hull. No
thru hull at all, and it works great. No temp or speed readout, but
for under $100 it shows the fish, and the bottom contours just fine.

I don't care about seeing fish... I just figured for the boat I have
I didn't want to spend more than necessary to have a depthsounder.

I didn't use epoxy on the transducer because they do crap out
occasionally. Mine is on centerline just behind the keel. I guess
there must be some degradation when heeling, but I can't tell.
