Prop nuts
 
the prop nuts that I need are left hand 1-1/4x7(to fit a 1-3/4in. shaft) the thick one is 11/4 in. Thick and the thin one is 3/4 in. Thick the nuts must be either bronze or stainless steel. Thank you.

Most any reputable prop shop should have access to these, have you tried them?

Ordered f McMaster but they are not the correct width. Too wide. Not enough room f cotter key to lock as they are not self locking. Don’t want the nuts to fall off while underway. Thank you.

That would be an easy grinding job to get them to the correct width.

Yes, thank u. I am looking f a machine shop to do just that.
May have to wait until next haul out as Friday is it!
Thank you all again.

Hate it when your nuts fall off underway... make sure you put the thin nut on first and the thick nut on last.

Best practice also includes drilling but and using seizing wire vs cutter pin.

On this matter, of all the articles out there, I found this one to best explain the mechanics on why to use the thin nut first. Makes perfect sense.

The naval guidelines for ships is also a good reference. See page 96 regarding jam nuts
