Just removed mine a few weeks ago. Actually I removed both my speed and
my depth transducers. The speed transducer was bedded with some normal
type of bedded and I had little trouble popping it out with some
vigorous pounding with a 3 pound plastic deadblow hammer.
The depth transducer was apparently bedded with 3M 5200 and nothing
would budge it even slightly. It was essentially welded in placed.
I finally gave up and used a 2 inch hole saw from outside and cut it
out. The hole saw bottomed out before it was free, so I had to stop and
hack out some of the transducer with a hammer and wood chisel before
finishing up with the holesaw, which also left me with the 2 inch hole
needed for the new transducer.
Needless to say, I bedded the new transducers with Lifeseal.
If your transducer is bedded with 5200, you will not be removing
anything suitable for repair. Defender can sell you a replacement for
around $100 or so. I went with a retractable model so I can pull it mid
season for cleaning.

More on removal.
So I looked more closely at the transponder and found that it appeared to be held in
place with a threaded "collar" - this came off easily. However the transponder
itself won't budge. I tried to tap the top of the transponder with a mallet, being
careful not to damage the wire, but there was no noticible movement. There is a piece of
plywood bonded to the inside of the hull which gives allows the collar to be screwed
tight. The hole through the plywood is tight against the transponder, but I don't think
tight enough to hold it in place against mallet taps.
Am I missing some other retainer - or it the through hull itself threaded?

I need to remove my Datamarine transponder to send it to DMI for repair. Does anyone
know how it is held in place in the through hull. I can't see any retaining pins etc -
yet it has a "t" like handle which implies it should be removable with ease.
