What the f@ck is going on? my 86 comp, rudder would come right out, this boat... I've been fighting with it for a week. Loosened the nut off the threaded stud but it WILL NOT come out to allow removal of that arm... my lower O-ring i leaking and want to replace it. This a minor problem that's keeping me on the shore and pissing me off to no end... Am I missing something?
