Assuming it's a MG? That's one of my biggest gripes with them.
Anyway... a friend of mine bent his once, and I even bent mine once, slightly, but was able to straighten it out without having to replace it.
If you're not sure about it, give Nick a call at the Trolling Motor Doctor and he will give you the scoop on the replacement process, as well as give you an awesome deal on the part(s).
I've dealt with him in the past and he's a great guy.
