The discussion is about removing an old depth transducer and replacing it with a new one. jonlewit is having trouble removing the old transducer’s nut and is looking for advice. Vela33 suggests modifying a sawzall blade to reduce scoring, while NS233 recommends using a Buck Algonquin Step Wrench or an oscillating tool to cut the locknut. jonlewit eventually uses an oscillating saw to cut through the shaft and removes the old transducer. He then asks for advice on filling the gap between the old and new instruments, and NS233 suggests using a decorative trim ring or a bridge clamp to patch the fiberglass. Vela33 recommends using tape to attach a board to the outside of the hull. jonlewit updates the thread with his progress, having used4200 to fill the gap, and asks for advice on mounting multiple ST-60 instruments. NS233 and Vela33 offer suggestions on layout and considerations for mounting the instruments, including thinking about how they will be used and which ones need to be visible when the door is open.
