You'll find that to be a 24x5/16

Actually I had it reversed, but I think you understood it as 5/16" shaft with 24 threads/inch.

Since YS engines are manufactured in Japan all the threads are metric (fortunately...)
The prop nut thread size is actually 8x1mm

8x1 is the correct answer.

Interesting! I just used a prop nut off my FZ 110 to seat a ST 75's prop and the ST 75 is a 5/16 x 24 (also made in China, albiet formerly made in Italy)

There's a possibility that I may have mislabeled the nut. I'll check it out when I get home tonight.

sdcranford - ya might want to wait and verify this with Troy when hew returns. I'd hate to cause any grief with bad info.

All YS four stroke engines from the .63 up have crankshaft threads 8mm x 1mm.

This is very handy. All my prop and spinner mounting hardware works on all my YS engines.

8mm x 1 is correct.

The reason that your 8mmx1mm fit the 5/16-24 is that the thread pitch of 1mm vs 24 is very close and for about 1/8" there is not enough difference to cause binding. If you try to thread on something threaded deeper, say a alum spinner nut, you would find that a 5/16-24 spinner will go about 2 1/2 turns on the 8mmx1mm shaft before you would get binding (cross thread). Don't ask me how I know this
