You will not be able to remove the bolts without removing the keel and even then removing the bolts from the keel is not possible without destroying the keel. The bolts are "J" or "L" shaped and cast in place. I would remove the nut and stainless washer then clean up the threads as best possible while in place. You can probably get away with one bolt at a time while in the water and then torque then properly at first haul out. If the hull to keel joint is sound I would not intentionally disturb it.
