What you want is a good Polly laminating resin.
I would use some 22 oz bi-axle and alternating with some 2 or 3 oz cloth.

Curious of your plan of attack.  Are you planning on filling in the entire hole and then re-cutting for the new intake?  Have you laid in the berk intake to see exactly how much and where you need to add or remove?  I would think you'll be working from both sides (top and bottom) of the hull, which means flipping the boat.  Best way I can think of is to make a template or mold of what you want to add.  I would use a polyurethane  laminating resin for sure, not epoxy, and the bi-axial or heavy mat like Jake said, it's what your hull is made of now.  I would think a gallon would be plenty and maybe a yard or yard and 1/2 of clothe if you don't waste it.  Are you closing in the transom any?
