tazz,
Never mind - I see that you cut off the back (solid) part of the scupper.
Another question - why did you use 3/4" vented loops when you used a 1" scupper and shut off valves? So is the fill tubing 3/4" or 1"? Or a combination of both? Why not go 1" all the way to the bag?

I, too, am thinking about the single inlet for 3 pumps, as that sounds like it will increase the overall fill rate dramatically, however I am interested in 2 of the questions above, being do the sacks really not fill AT ALL, and perception on fill times, unless you timed the differences..

I used a 3M Whit silicone/adhesive that I purchased at West Marine. I think they have it at Home Depot. After using the stuff, i think I takes about 24 hours for it to dry 100%. I drilled from the bottom of the boat in. No I did not need to run it back wards. There is no direction for the carbide bit. I kept the front of the scupper (screen) on to keep debris from going into the pumps. I did remove the back end. Yes it did fill while on the way. When I took the cup off, the autofill (HAHA) was over. It takes a total of 7.5min to fill all 3 bags 100%

Not yet. After talking to the dealership more come to find out that even though I have an 08 xlv and got the GG3 system thrown in with the deal, they are wanting to install the 09 GG3 system which is the 3 Jabsco pumps instead of the single pump that came with the 08 GG3. However, here's the weird thing. I know this dealership has been around at least 20+ years because it was there when I went to college. I don't know how long they've sold Moombas but I think pretty much since Moombas have becoming popular years ago. The service manager said that my boat will be their first install of the GG3 system for a customer and that all boats they sold either already had the GG3 system from factory or the customer did not care and just used the standard system. The service manager said, they are still waiting on the Jabsco pumps and have just got one pump in for a customer that was waiting 5-6 weeks.

Honestly, I did not want to change out the entire hose system. Plus I could not, for the life of me, get the darn 3/4" connectors off the bags. So instead of buy new bags, hoses, connectors, so on and so on, I stayed with the 3/4" Still very happy with the system 7.5min to fill in not bad at all.

drilling depends on what you have installed already.
jabsco system requires holes in the bottom of the boat for the pumps. assuming one per pump, but ed can speak to that requirement as he has it...
tsunami/rule system requires 1-3 holes in the hull depending on whether you do a manifold setup or one scupper per pump, then holes in the hull for the drains.
personally, I like the tsunami setup as you can tell when they are full from the overflow out the side of the boat, cheaper pumps that shouldn't wear out as quickly and flow more than the jabsco. believe that you have to set up a timer on the jabsco as well to shut them off when the bags are full. with the tsunami, to upgrade the bags, just put in a bigger one and shut off when it drains out the side, jabsco have to change the timer settings. jabsco pumps don't fill while moving, tsunami's can if not installed right.
there's pros and cons for each setup..
I'm doing one intake and a manifold for 3 pumps with the vented lines. a takeoff of tazz's system, think it's the same one fman put in..'06 Supra Launch 20SSV-gone but never forgotten
