To really do it right (do it just once) you need to make sure there are no structural problems and if there are, correct them. Drop the keel, yes, drop it, at least enough so you can get in to fully access the joint and clean it down to bare hull and keel. Then apply 4200 or 5200, resecure the keel and let it cure. If this is done with 5200 and there are no structural problems, the 5200 alone can typically secure the keel even without keel bolts. (You won't want to even try separating it in the future if you use 5200. 4200, you'll only have to fight it.)
If you just "gob it in" without cleaning out and rebedding the entire joint, you'll probably have to keep fighting the leak forever.
