I also had my doubts after being told that a transducer wouldn't fire through plastic or fibreglass .........I don't think the manufacturers really have any idea that we use these things on a kayak and what the capabilities of their products are!!!! I run a standard Garmin 140 and it's been running in hull for over two years now without issue firing through the ply.
Provided you have no voids in your ply, are careful not to get too many bubbles in your epoxy/glass or graphite coats and are careful with the sealant sticking the transducer in it's fine in my yak
Apologies for off topic stuff.........
Build and paddle your own kayak - it doesn't get much better than that!

I live in the southern hemisphere the evidence seems to be conclusive (sorry Scott)
I'm reconfiguring the waterline on my boat raising it a bit amidships and...........................................I'm gonna graphite everything below the waterline
Now I've got to wet dry all that lovely gloss so I can varnish
I'm guessing graphite bottom don't need varnish
Scott in the end I decided to go with HM and Flump and graphite over transducer slot.............time will tell
Thanks for link Jimmy W I'm kinda thinking I might go for the silicone glue it in path........ as transducer is in bow storage area and I want to try to keep it dry(storage area that is)
Maybe its not important........ boat might sink on first outing then everything gets wet (no ofence ment Matt)
