Waterproof foam

[RollingWanderer]

I had a pwc lift (http://www.jetdock.com/pwc-lifts.asp) give to me that is made up of individual flotation cubes. Three of the cubes have holes in them. I could buy replacement cubes, but that'll cost more $$$ than I want to spend on this project. I've already pulled the lift and drained the leaking cubes. My plan was to fill the bad cubes with a waterproof foam, then patch the holes, completely if possible. I'm figuring at some point I will probably get some leakage into the foam filled cubes. I'd like to use a foam that has a chance of surviving under these conditions.

Does anyone have any suggestions? At this point canidate #1 is good 'ol expanding foam from the hardware store.

Thanks.
