I would loose all water coming out when at idle but water would poor out when the boat was just above idle speed. So back to Ace hardware and now I have relocated the 2 pumps down low and hope to pick up the 3rd pump soon as im going out the coming weekend surfing with friends. I will actually have a 4 pumps filling 3 bags. I will post up some photos when done. 2 of the pumps are just for filling the surf bag.
Makes sense, these pumps will not prime themselves, need to be lower than the draft line when the boat is in the water. If you look at my install, my pumps are literally across the bottom of the boat. I have had no problems priming, the lower you can get them, the better they will prime. Make sure and remove that scupper off the bottom or else you will get water in your bags while driving. I chose to grind my scupper down rather than buy a new 3/4" inlet because all the holes and screws line up with the current intake grate. Did not want to have to fill any holes in the bottom of the boat.

You are correct about the 1200's, I was discouraged by wakemakers to use them because of the difficult thread pattern they have used to match anything up to it. According to wakemakers they did not see a significant difference in fill times from the 800 to 1200 model.

Good luck with your install, post some pictures when you are finished. When its all done its a much better system than the stock setup. I think it might even be better than the '09 JABSCO setup because aerator pumps last forever and can be run dry without damaging them, unlike the impeller style that will burn up if ran dry. Plus, the tsunami's put out more GPM's than the JABSCO's and cost much less (Tsunami - $35, JABSCO - $265).
