Loctite anyone?

+1 Replace the nylock nut every season or so.
I can't imagine one spinning off though. It takes a fair amount of running torque to turn one on the shaft, and it is seated on a prop hub that is splined in, and can't start to turn.
I'm guessing more people have lost props due to broken propshafts than spun nuts. I have seen it happen on inboards, but that is a different deal with props seated on a shallow taper, questionable keyways, and double-nuts instead of locknuts.

copied from 700 NXT owner warning. double nut
Mercury had a "bulletin" that as far as I know was never sent to customers but manufactuers and service departments. This bulletin was to let dealers know that they needed stop using the number six style prop shaft single nut immediately in favor of a double nut system. In some instances this nut has backed off and resulted in lost props or even worse. Well I got to experience "the worst" first hand. I lost a $5500.00 Herring prop and broke the prop shaft. I found out about the "bulletin" after the damage. I was six weeks getting parts last summer and never was offered any assistance from Mercury Racing. The most ironic part of the story is that the previous season after winning the Lake Cumberland Poker Run a Marketing representative from Mercury Racing came up and introduced himself to me. The conversation was that he knew that we do alot of poker runs and that he appreciates us promoting the Mercury Racing product. He told me that if I ever needed anything to please get a hold of him. Man,I sure wish I had kept that business card. That letter should have been sent to ALL Mercury 700/NXT customers!!!!!!
