I was just reading all the warnings I got and taking them literally. I'm
sure it wouldn't have made much difference. My biggest concern was not
putting it directly over the cast iron keel. :-)

I've heard of that, but if there's a gap or significant air bubble, then

mis-reads. At least that's what I read. I don't think mine was absolutely
straight up and down either, but I tried to get close.

The instructions for my $80 fishfinder, which I use as a backup for my
"real" depth sounder, says emphatically not to use a glob of silicone
glue to mount the transducer inside the hull. They suggest epoxy. It
may be a problem if you are using it to spot individual fish, but I
can tell you from my experience, and that of quite a few others, it
still works just fine as a depth sounder if you make a glob of clear
silicone and press the transducer into it. It's really not that hard
to avoid air bubbles. I think the loss in sensitivity is slight at
best.
