Ha! I should clarify a little. I don't have a real fat wallet...

I have a Tsunami 1200 pump sitting on the shelf waiting to go - so buying a couple more 1200 or 800's is not a huge expense - definitely cheaper than a Jabsco or Johnson!

I have "some" of the plumbing - hose, fittings laying around as well. I would still need to invest in a few pieces, fittings, switches, etc. though. The boat also already has drain and vent lines and thru hull fittings for those up under the rub rail, unfortunately they are out the back though. (I have a 400lb sac on each side at the moment, single fill/drain switch, but those are going away so it's sort of like starting from scratch)

I can see where we would be switching from riding normal to goofy, filling one side while draining the other and it would be nice for that to not take forever.

Are you also draining with 1200's? I have two little Rule pumps right now with my 400lb sacs but have no idea what they are rated for flow. They seem slooooooooooow to me... That's where the cost of a couple extra drain pumps would come in but that's not a big deal.

So basically I'm ruling out the reversible pumps and trying to figure out what to do with multiple pumps.
