Fast pumps for additonal Ballast tanks

[seanxtreme3000]

SuperAirBallastDiagram.pdfAttached is a diagram i have found that i am planning to do to my boat.
First off i can’t figure out that front sac and how it will fit up front. the cooler on the left of my 03 SANTE210 is fibreglasses in, and I’m sure everybody else’s is too. Do you cut it out? Or does the sack not but up to it?
Second. so what will be a big, fast but reliable pump to do all this work. Does anybody have bigger pumps that will fill up and empty their tanks faster, or does this all have to do with the plumbing? Lastly if I just kept my stock tanks would upgrade the stock pumps and plumbing make this process faster?
Thanks

If you are going to use a reversible pump, the Johnsons are the fastest that I am aware of. You can find them at wakemakers.com and a few other places. I have 2 Johnson pumps off of a single 1 inch thru-hull, and they fill up a pair of 400 lb v-drive sacs in 2 minutes and 57 seconds. I think that is pretty fast.

I have the Jabsco pumps which are a bit slower than the Johnsons, but fast enough for me. I usually warm the boat out of the gate a bit and adjust the wake accordingly as I am going so overall speed was less important than reliability (but I have heard that johnsons are just as reliable). I fill two 1100s on each side of my V-drive through a 1 1/4 inch through hull, and the front and ski locker sacs though a second through hull. I have four total pumps.

As far as the bow sac... placing that was a bit of a PITA. I used a reciprocating saw to section the bow cooler, and then a multitool to cut around it. I carpeted the exposed fiberglass and built a barrier with glassed plywood to protect the bag from the heater element under the helm. I have all of the through hulls for the ballast system hooked up to ball valves that can be accessed behind the engine, just forward of the transom. I ran the fill-empty hoses up the gas tank into the ski locker, and the vent hoses out the hull forward of the helm.

I have pics if that helps
