I think that it is pretty cool that Skiers Choice has gone to a 6 pump system to fill and drain faster. That being said, even running enzos or #1100s, the fill times aren't so bad that after you drop in, you begin to fill, and by the time you're ready to ride, the ballast should be full. If you are turning your boats off to fill and drain, I'm pretty sure the pumps run a bit faster if the boat is running. So for my humble opinion, rewiring a boat, adding pumps, relays, switches, isn't worth the few minutes extra you may save while out enjoying the sunshine and your friends and family.
