Excuse my vocab, ive only owned a boat for a couple years. The locking clip on the trailer end of the hitch is broken. I can no longer "lock this down" on the ball hitch. I would just replace the whole hitch on the end of the trailer frame but the trailer has its hitch welded to the frame. I have tried to find just this problem piece without luck. What can I do or should I give in and take it to a boat shop?
