Winston I had delam with no water
intrusion in my cockpit floor. The floor would "crack" when it was flexed, as if glass fibers were rubbing. When I drilled small holes half way through the floor the plywood shavings that came out were dry. So I drilled apprx 1/8 inch holes in a one inch square pattern ( put tape on the bit as a marker so I wouldn't drill through the floor) at the soft spots and injected with epoxy with a plastic syringe. The epoxy took about 30 minutes to set up, so I just kept topping up the holes during this time. The floor still flexes if you jump down on it, put no more "crunching" sound.
