    I prefer not to use foam. The inner liner will get water in it and it needs to drain. I seal the openings with trimmed pieces from the removed pieces and drill drain holes at the rear of the liner behind the midwall.

    I drilled a hole at the bottom of each rear gas tank strap mount at the bottom and drilled a hole at the bottom of the water box mount to help allow water to drain from the inner hull.

    Spray in foam. I use a long hose, and fill up the inner liner as much as possible, and seal off any unused holes. I've never had a drop of water in there, even after swamping the ski.

    +1 on the drain holes.

    the only reason to fill in the cuts or cap them is to stop anything that you drop from disappearing. Mine aren't filled or capped.

    I used spray foam to fill it, then when I was doing the resin on my Pump, I painted the resin over the foam to harden it up, so I didnt get foam deteriorating and making a mess

    Do you have a link for the spray in foam?

    I just grabbed a can from home depot. It said waterproof, and I wasn't too worried about it.
