I am not sure, but McMaster Carr??? I am guessing you will need to know the exact thread type and pattern.

Have you tried a local prop shop?

Machine shop.

Any shop that does marine shafts. Any prop shop should be able to tell where one is.

I’ve bought prop shaft nuts from McMaster in the past. That would be the place I’d check first

McMaster Carr carries 1-3/4" - 8tpi in standard threads, but I don't see any reverse threads. Are you looking for stainless or bronze nuts?

It's possible you'll need to have them custom machined if even prop shops can't get them.

Contrary to many popular beliefs..The more narrow nut goes next to the prop, the larger one is the "keeper'

Are reverse threads (LH) on prop nuts common? What about the case of counter rotating twins - is one side LH and the other side RH threaded? Just an inquiring mind …
