Seidelmann prop-shaft through hull
My friend discovered a soft spot and some water drips just forward of where his prop shaft exits the hull. He excavated the area and discovered an area of fibreglass filler covered with some marine "Bondo". This was external to the cast hull. When he had removed this material he could push against a rubber/neoprene barrier, visible from inside the boat. This appeared to be a damper of some kind. It is possible to push a screwdriver around this from inside the hull to the outside. He is, naturally, quite alarmed. Is this normal? If so, should he simply replace the "wad" with new, and better material?
