I recently got my dads suprjet that I helped rebuild the engine with him top to bottom...... the ski is stock but the foam was completely water loged so I cut open the tray and removed all of the foam (over 50 pounds worth) and I plan on putting in foot holds. My plan with this ski is for it to be a surf ski and in the near future really get into some freestyle. What I need help with is what should I put in the now empty tray, I have seen a few threads for all sorts of stuff such as, 2 part pour in foam, beerpong balls, insulation foam..... ETC. What are your guys opinion on what I should do. I also plan to shorten the pole 4in, reinforce the engine bay put footholds in, run super valve and trim tunnels before putting in new foam. BTW Im looking for the MOST low end grunt per dollar spent. Any advice would help!

I'm a big fan of two part foam. I use 4lb foam from US Composites which gives you buoyancy as well as structural integrity. Others use ping pong balls, pool noodles and all kind of other things but they just don't make sense to me. No offense to those that do.

How do you recommend pouring that foam? Through the factory fill holes?

Yes, after you install and glass in the footholds, stand it up on end and pour in the foam through the factory holes.

Would you recommend glassing over the fill holes after done pouring so no water can get back in because for me that's where it came from. Also roughly how much do I need to fill the whole thing?

I just sealed the holes with some 5200 but a layer of glass will work. I'm pretty sure the 16lb kit is what I used and was plenty. Just don't try to do it in one pour.

Pour the two part foam into the open tray. Then carve/sand the foam to the shape you want. Fiberglass over the foam. I did mine that way and it's super strong and held up well.

I assume you are glassing back in the part of the tray you removed? If so then pouring in the foam through the exhisting holes is the way to go. If not then the mrstarke44 method is ideal.
