Just trying to figure out the thread on the end of my boat prop shaft, shaft is 1-1/4 so presumed the thread would probably be imperial as it was built early 80's and in Cornwall. Anyway, just tried a 7/8 bsf which was my first guess and got about 2-3 turns and jammed up. What are the other close threads that this might be?
