[FISH11]

I removed one before to remount it outside in the water. I very carefully used a sharp and pointed knife (Buck or some similar heavier blade knife) to start to get under the edges of the goop and the hull. Once I was able to get under the goop and lift up on it, it started separating form the hull and a had to break off and scrape what was on the transducer. Be real careful to not poke a hole in the hull, the knife has to be held flat against the hull and only attempt to start under the goop edges. After the goop starts to separate switch to using a wide flat screw driver and slide it under and the twist side to side. Might even try first to push on the outside of the hull were the transducer is mounted to flex the hull material at the area of the goop, to help start to separate the two. Good luck
