Yeah, and the answer is not very well. You can't tighten them properly cos the pin hole has to always line up in the same place so they typically have shim washers under the nut. Better to replace with a castellated nut.
you could cold chisel it off with a shape chisel on one side and then pin punch it
Reminds me to buy a s/s castellated nut for mine Ive a nyloc on the end at the moment with no prop I was go9jg to be lazy and drill a split pin hole through the nut and prop shaft.
So many jobs to do
Is that nut of yours Sir Jman still hanging off a Clansman?
Ok, maybe we can convoy. I've a friend that wants to rock climb at deal island.
24hrs Queenscliff to refuge, then a full day sail to deal from refuge.
