Derek,
If I had every nickel I spent on fabricating ballast systems, pumps, hose, hose clamps, barb fittings, sacks, switches, you name it, I could have bought three Hippo systems when they were around, and they indeed were the shizzle.
PP works. It works. I wakeboard with about four other people, every one of us has improved since I got the PP working. The wake is always the same height and width. You just have to have it right now. With the paddle wheel speedo. Don't piss around.
Heres the bracket.
