I had my prop shaft replaced this past spring. The bronze shaft was cut for removal. New ss shaft was inserted quite easily without the cutlass bearing in place. However, the shaft won't go with the bearing in place. cutlass bearing was inserted after shaft was in place using the previious bearing to tap new one in place. My boat is a 1993 C36 wing keel with elliptical rudder (not sure if new style rudder would make a difference). So, there should be no need to drop the rudder or to remove the engine. Cheers
