It's coming down to the wire as to taking my boat in for the ballast upgrade. I've seen/read some doing the 3 Jabsco with 3 intake, read about 1 intake with 3 Tsunami pumps, 3 intakes with 3 Tsunami pumps. Question is on the Tsunami systems using multiple intake pumps, how many drain pumps are you guys using and how? Seems to be pros and cons to each system.
