My 07 Supra OEM ballast hasn't worked right since I've owned the boat. I'm no longer replacing sprinkler valves or dump pumps.
I'm considering installing 4 Jabsco reversible pumps. 1 for the 1100# center sac, 1 for each rear side sac, and an extra pump for temporary surf sacs. The plan would be to add 3 more grates to the bottom of the boat so each pump would have a water intake, and a spot to dump. No more draining through the holes below the deck and rubrail. I'm assuming all I'll need are the 4 pumps (that come with switches), hose, and fittings.
