well, i don't want to bash the boys over at wakeworld, i think they all feel bad that they screwed them selves out of piles of money so..., that may be bashing, i'll stop. glad you came to the board, i know i didn't help you, but you are right, this board is very helpful. guess that is the moomba family way.
see if someone is in your area that you could go look in their boat to see how the plumbing is run. that is the most helpful thing to figure out how to do ti yourself.
