Transom & Stringer Replacement

[SkunkBoat]

an '82 only has foam in the fuel tank compartment (99% sure of that)
Don't use "treated" wood, use dry marine grade AB Douglas fir or at least BC Douglas fir if your trying to save some $. Coat it with resin. Treated wood is southern yellow pine(soft and knotty), wet and doesn't hold resin.

I'm in the middle of a pourable transom project.
My '84 transom took all of 15 galllons @ $187 per 5 gal pail.

The worst problem with Arjay/Nidacore/CarbonCore is the lack of clear instructions and expectations. I'm trying to get clarification from them about the properties of cured product. Someone on the forum says "rock hard,can't get a nail in it" but mine is solid but screwable,drillable. Thats what I expected for a core material. I have an email out to Carbon-Core asking if I am correct.

see my thread for updates.
