It can be done, it just takes patience. You need to be able to get under it with a thin butter knife or putty knife. What I did was to chisle the epoxy around the transducer down untill I could get the putty knife into the seam were the transducer meets the epoxy. then you just have to use friendly persuasion and pry it up. A dremel tool works great for grinding down the epoxy.
Hope it helps
