Replacing factory-installed transducer in bilge?

[Walt Simpson]

Replacing old defective Lowrance transducer and just a little uncomfortable with removing the old one. Anyone willing to share their experience? Boat is an '00 520. Thanks...

Depends on what type it is. My 97 came from Ranger with "through hull" transducers. If you take them out there is a hole in the boat. I just left mine in and disconnected them.

I've changed a couple of them out. I use a cold chisel and a ball peen hammer. Put the chisel almost flat on the floor against the base of the transducer. Give it a whack with the ball peen. They usually pop right off the floor. Clean off the old epoxy using a side grinder with a cat's paw (flapper laid flat in a disk) and you are ready to glue the new one back in the same spot.
