have had two keel bolts break off....has anyone had this happen? Some one said that you can fiberglass in the whole keel, just make sure to run the glass at least a foot into the boat. Would like to come out of this as cheap as I can. Heard too that you can drill them out and put a sleeve in and a bigger bolt. Not sure if heavy duty glue would work. Or take off the keel have them drilled out and reset.
