Expoxy is very strong in some ways but weak in others. If you can get a piece of wood on it and can get a blow with a hammer in a side way manner it may just pop loose. I have taken several out by striking the xducer as though you were going to slide it to one side by using a piece of wood and a hammer.
I sort of tried this for a while. I cant get a good enough angle on it the way it is buried down in there without removing a ton of wiring, batteries, charger and maybe even power-pole pumps. I think I am going with the abandon it approach. Thanks for the input though!
