I would be interested in the answers, as well. In my case, the seahood is attached from below.
I am looking for an option of injecting “something” into the existing holes that would not flow out immediately (one option would be to stop gravity, but short of jumping on Edd’s Enterprise, I see this not feasible).

The holes for these screws penetrate the balsa core of the cabintop and were sealed with white caulk. There is no way to through bolt it. I'm planning to overdrill the holes to 3/4" and fill with Thixo flexible epoxy and then drill the holes to 1/4" to take plastic masonry anchors. The SS wood screws will like these anchors, be removable and the core will be better protected from water penetration. I'm trying to decide between using plastic masonry anchors made for wood screws, or screw in threaded fittings and use machine screws. Or maybe I should drill and tap the epoxy and use machine screws? Any better ideas?
