Steve, it's been a while since I unstepped my mast but I do remember that there is a keel bolt located under the aluminum plate. If I remember correctly the "box" is what appears to be wood glassed to the hull. If it were my boat I'd unstep the mast and make the repairs. I know that isn't what you want to heat but given some of the problems I've had with my boat over the years I recommend a complete and thorough inspection. I'll be interested in hearing what you find.
