some of the owners fixed the leaking keel bolts by grinding off a couple of inches of gel coat each side of the keel joint ... applying west epoxy and two layers of light weight matt basically sealing the joint from the outside ... then borrow a set of templates to make it work.
it depends on whether you believe this boat is a life time investment.
You would not believe the shape of some of these keels if you striped them down to the base lead and looked at voids, holes, gouges, and repairs over the last 30+ years.
when the boat is pulled see how bad the joint looks, it may just be one small spot that is causing the leak.
rebeding the keel can be an engineering job.
