Curious if anyone has had luck epoxy mounting/ encasing a totalscan transducer into to inside hull of a fiberglass boat..  I was wondering if you get a ok scan through the thicker epoxy on the sides of if it's just to much material depth to get an accurate reading...

I would not recommend doing an epoxy in case you want to remove it or move it at a later date (just my two cents).  A method i use and like a lot is the use of plumbers putty.  This putty is super sticky and should stick  to the fiberglass boat with little issues./ if not take a little sand paper to rough up the area some so it will stick better.  Using the putty make a volcano shaped ring,  Place the transducer in the middle of the putty ring and  push some putt on top of the transducer so it stays in one spot.  Then fill the volcano with a little bit of water, to help with the reading.  This method allows you to remove and reuse the putty as much as you like and does not damage the kayak and is not permanent. 

Hope this helps

Marine goop would also be a good bet.

I didn't like the idea of a more permanent installation, especially if I got bubbles in it. I have just installed my lowrance transducer using the plumbers "Duct Seal" Zack mentioned. As I had two transducers, last week I compared the two, with one directly in the water.  I could detect no difference to the one mounted inside the hull of my Hobie.

I built a wall around the transducer then, with a rolling pin, rolled out 1/4" thick layer of putty between two sheets of wax paper. I then laid in the transducer, poured water inside the wall, put this layer on top, sealing the edges to the putty wall.

Seems like with that method you could just cut the bottom out of the right sized sealed plastic container and glue / putty it in..  Have a bracket or mount transducer on side of the container and just fill it with water...  I've seen lots of the foam or putty posts..  I guess part of my question was if it even theoretically possible for the rounded edge of the totalscan transducer to transmit through the 1/2 inch of epoxy you would need to cast and hull thickness as well.  The kayak I'm gonna get is a little tricky to mount a transducer because you have to cut a hatch trough the fish box to get to the outer single layer and there is really only about the width of the transducer to work with so it limits things more to a permanent setup..  or some knuckle scraping annoyance at the least if I were to try the putty or foam methods..  the boat manufacturer recommends epoxy mounting for best readings..  I'll figure out something when I get it..  I'm might just end up with the HDI one as I know it's simpler it install...
