Friction arm does not stay tight.

[Rkeane12]

I have a F70 outboard that does not maintain the friction setting once I set it. I need to carry a wrench to tighten it several times through out the day. Today I took the nut off. I noticed the main body of the bolt moves some but the head of the boat does not. I also noticed the the bolt has what appears to be a slight cut in it. Is it possible the bolt is cut? I have tried to find the replacement bolt and directions on how to change it. So far I have had no luck. Any suggestions would be greatly appreciated.

how can the head and body of bolt not move as one?
Unless it is broke in half.
or were you talking about the bolt and boat
