1958 18 hp johnson prop nut size

Would anyone know what size diameter and thread pitch the prop nut is for this motor? I'd like to be able to just buy a nut and drill a hole through it rather than spend 30.00 on a new prop nut.

Can't help you on the thread size, but if you have a hard ware store close, get a couple of different sized castle nuts and try them. You will not have to drill a hole if you use a castle nut. You should use a stainless steel one if you find the correct size.

This is just C$10.00 Antique and Classic Outboard Motor Paint & Decals
There is probably shipping though. But I think it beats a rusted on nut!

Make it a stainless steel when you figure out the correct size. Goes for Cotter Pin, also.

I was going to offer you a "real" prop nut, but I guess you don't need it now.

I would much rather have a 'real' one. How much, and where to send you the money?
