? about pourable foam

[lime4x4]

Working a 1986 268 searay weekender. Started with replacing the transom which turned into replacing stringers and bluck heads. Also found alot of wet foam.How far will a gallon of pourable foam go? Does it expand with enough force to distort wood? The original design of the boat had foam in wooden square boxes (shelves) with a hole in the center and foam poured into the hole.

Lime4x4, a couple of options you'd have, would be to replace the poured in type of foam with other flotation, such as solid sheets of floatation cut to size. Many of us do that to prevent rot when the foam gets wet and holds the water.

if your set on using the poured in foam, do it in stages, make small batches and pour them in one at a time, thus not doing to much to upset the balance of the decking or surround structures.

I think that the Coast Guard standards require foam in vessels under 21-feet, but I could be mistaken.

Anything that helps a boat float or float longer should the hull be breached is good though!

That pink stuff can be glued together using Gorilla Glue, then cut to the exact shape you need or like mentioned, put in the spaced you need one at a time.
