Removing Thru Hull Transducer
Fairly easy task. I just replaced the transducer on my 76 C&C 30 last spring. Because there was limited access from the inside, I had to do everything from the exterior. I drilled a pilot hole completely thru the face and followed it with a 1 3/8 inch forstner bit. Then, using a saw blade I made several vertical cuts in the remaining wall of the transducer. Be careful not to cut thru the eall and into the glass. With the help of a narrow chisel and some prying, it came out in several pieces. I was fortunate that the primary bond was between the flange and the hull vs along the entire length of the threaded shaft.
