Looking at the prop lock from iBoats I have a question about how do they keep the nut from coming loose and falling off. I see no way to use the cotter pin or the tabs that merc uses.

I had an OMC Cobra for 12 years (19 total) when I lost the pin when changing props and ran without it. I had never seen the nut back off to the pin so I thought it was not really needed. Guess what it only took 30 mins for the prop to find the bottom of the lake and I sill hear about it 8 years later.

So how does the prop lock keep this from happening with no pin or tab ?
