Pour foam question

[Streffpilot]

Hey, iBoats sells a pour foam in both quarts and gallons. How much does a gallon fill? I have a 17' fiberglass bowrider. I want to replace the pink board foam that I put in, and was wondering how much i would need?

The specifications of the foam you are looking at using will tell you the expansion ratio for it. For example, the specs for this particular foam

http://www.iboats.com/Evercoat-Foam...67702032--session_id.542897757--view_id.38103

States that the expansion ration is 25X (1 cubic foot per quart)

has some good info on how you roughly estimate your foam to keep your boat afloat. Best of luck

Depends on whether it's 2lb or 4lb.

See the Hi-Bond site

4lb will be half that.
