M_Boats: Centerboard question M15

We jacked my M15 up a bit to see if the centerboard was still stuck (from last summer) and it wasn't; that's good, but the pin that it swings on seemed to be coming out of one side of the keel more than the other (like it had been pushed part way out. Is there something that is supposed to keep this pin in place? It looked like it might have at one time been epoxied in or something like that. Bobbie
