I posted a few pictures in the photos area under the title "internal transducer mount".
The transducer that I am using is one that is normally intended for an external transom mount, not sure if that's what came with your Humminbird. If so, in order to set it up so that it shoots through the hull, it has to be submerged in liquid. That's because the fiberglass isn't very opaque to the sonar frequencies, but air will completely stop them. The mineral oil seems to work well. It has never permeated or affected the resin, and it hasn't gotten moldy or anything. A regular through-hull transducer will work a little better of course, but drilling a hole in the bottom of my boat while in the water is pretty high on my "bad ideas" list. ;-) Glad to provide additional detail if you want, just let me know. --- In [email protected], sharon speller <unclesha...@...> wrote: > > I would love to see some pics of your mounted transducer.
