You can buy the Nyloc brass and S/S nuts at your local nut and bolt/automotive fasterner store for around $7 and no shipping. While your at it, buy a extra or two to have as spares.

Don't forget the cotter pin. Nylock or not, once you loosen it a time or two, it will start to work it's way loose. The pin is a few cents worth of cheap insurance. I'm not sure if a castle nut will work with the MC prop and shaft, but from what I can see, once they're on, they're not going anywhere unless you want them to. I had a nylock nut back off just a bit before the pin caught it. Glad I had the pin. What a racket that prop made in reverse. In forward gear, it snugs up well enough so you don't hear it.

That sucks.

I thought this was going to be a thread about you being a prop fanatic. Oh well....:confused:
