Greetings whaler people. I am thinking of using a product called "Great Stuff" when I
repair the drain-hole in my 64 Nauset(after I replace the tube of course.) I thought that it might help provide a relatively water-tight space as previous owners have
boogered up the drain area into the transom
when chipping ice. Eckkk! Any thought? Thx!

If small holes I would use an epoxy or 3m's 5200. Great stuff will not keep water out.

Wayne:
Great stuff, 5200 and Gorilla Glue are all a type of polyurethane.
Great stuff: messy, expands 3times when it cures, messy, has questionable resistance to certain environmental attacks, and messy.
Gorilla Glue: kind of a thin clear runny stuff , also expands when it cures. Works best when gravity can direct its flow, or could be injected with a syringe. Might run out of a repair area if now temporarily confined. Might work really well to tighten an otherwise loose screw in damp wood, eg, a loose bow rail fitting. Verdict: messy but has possibilities.
3M 5200. Can you spell permanent? It's in a form which is particularly useful in boat repair. Hold its own shape, rather than self flowing. Verdict: good bet for many apps
West System epoxy.: thin but can be thickened to any consistancy or stabilized with wood toothpicks or shavings. The true "great stuff" as Bigshot says.
See the following link for an interesting indepth description of the various sealers available in a tube:

Thank you much people! I shall heed your advice and I think 5200 sounds like a safe bet.
