Prop nut needed

So a week ago I was reversing out of my slip when my prop nut backed off. It's an odd ball nut.
I'm looking for a 1 1/2" left handed (reverse threaded) nut with a 12 thread pitch on our in either stainless or bronze. I have tried all the prop shops locally and the usual suppliers like Fastenal and mc Master Carr. Any help would be appreciated.

Check with Misumi?

Good luck!

Hey Sharky - I live in Rancho. I can PU and send/deliver the part if they have it and that is needed. 

A 1 1/2-12 propeller nut is a huge nut. Did you measure the outside of the nut ? That nut would use a 2 1/4 wrench. Could you describe the motor make and horse power. What is the diameter of the shaft where the nut goes?

It's a big boat.

One more question is it a standard 60 deg thread profile?

I had a custom one fabricated. Thanks for all the help guys.

Good to know ... that was going to be my next suggestion.  Hope they made you a spare ... or two.

Glad to hear you got one, even if it had to be built from scratch.
That's a really cool old boat you run.

It's got a Detroit 4-53, 2" shaft.

She's a BEAUTY!
