So pulled my rudders apart today to find two very worn(nearly failing ) cams and a sister screw in only the port side. Not a good look really...think we were really lucky not to loose the cam while sailing( ive only owned the boat for 2 weeks ). My difficulty is that the casting itself has been worn away where the screw goes through and in a short space of time will not hold it correctly. Rather than rabble on -i took a picture.Any ideas how this can be fixed or is it time for new castings
