Prop nut -- unusual?

[hmason]

I was just wondering. It would be my luck to have a diver change my prop and drop the nut and no replacement to be had anywhere. My starboard prop had right hand threads and my port has left hand threads. I am going to look for some spare nuts to have aboard just in case...

If a diver drops a nut and can't retrieve it I sure hope the diver is honest enough to tell you.

Well you would find out eventually...

Definitely!

Is there enough threads to get 2 nuts on? It might make it easier to get service in remote areas where these unusual nuts may not be available, or just carry some spares.

I believe there is plenty of thread depth for the two nuts. You can see it in this picture.

Yes it looks like 2 nuts will fit. Just make sure to put the full height nut on last... Just trying to start a debate about which goes first.

When I had a shaft done for a previous boat the 2 nuts were for different
diameters and counter threaded.
