Transom repair - Here we go..... (long)

[spareparts]

ok, heres a question I've been pondering over, what about combining the pourable transom with Coosa/Penske board. Cut pieces of coosa to loosely fit in the transom area, it doesn't have to be a close fit as the purable transom mix will fill in. Then pour the stuff in around the board, just wondering if there would be any weight savings, strength enhancements, or even cost savings. I've been trying to figure out a test to compare the feesability and strength as compared to straight pourable transom with spending too much $$$. Next time I'm at the fiberglass shop, I'm going to pick up some scrap coosa and part of an old transom, now if I only had the time
