FWIW and to expand on what I believe Morfoot is saying. There are three types of nuts: Castle, nylock, jamb. Shafts are supposedly set up for one of the nut types and the treaded end is a bit different. But, I really cannot tell the difference and the nylock or jamb nut should work on any type of shaft. However, all shaft styles will have a hole in the end for a cotter pin. Regardless of the nut style (I like the Nylock) you SHOULD install the cotter pin to ensure the prop is not lost should the nut back off for whatever reason.

Be sure that the nut is saftied with a STAINLESS STEEL cotter pin. If it were just plain steel it may have just rusted away allowing the nut to back off.

I'd say someone needed a nut at the marina you found the boat at, and it got 'gleeped' for another job.
Just be glad your hobby isn't airplanes. |

You can get a nylon locking nut instead of the factory castle nut making life easier where prop change doesnt require lining up and installing a cotter pin which can be a pain. However, you can only take a nylon locking nut on and off a predetermined number of times as the nylon wears out.

Man, I feel like an idiot. You'd think I didn't know anything about boats. At least I didn't lose the prop!

Yesterday, after putting my four plugs back in (see this post), I had yet another problem that ended my day - the prop came loose. At first I thought I'd dropped my transmission, but I inspected it and discovered the prop was spinning freely on the shaft. The key was gone, and now I'm not sure it was ever there. I bought the boat last year, and it had been abandoned for seven+ years before I got it. Now I'm not sure how the prop assembly is supposed to look. Mine is just the prop, a key, the shaft, and a cotter pin. The shaft is threaded, but there's no nut on it. This doesn't seem right at all. Can anyone post a picture of their prop assembly or tell me how it's supposed to look?
