Hello all, I entered prop shaft bearing in the search box and read many previous references without finding the one I wanted. The detailed description just posted is excellent but a long time ago someone suggested that to remove the old oil seals you should drill a small hole either side and then screw in two long screws which will make it easy to pull each seal out. It works!! The bronze bit is called a wearing ring by Amel because it is not a bearing but merely a device to seal the oil in and the water out. Before fitting a new one I had a local machine shop make me another as a spare as the dimensions are not all that critical since it is only an O ring holder. Someone also suggested that when the puller is in place on the prop and really tight a couple of taps with a hammer will make the prop break free. It worked for me.
