x-30 ballast system
 

For a few years every pump from the factory in my boat has slowly failed. I now fill around 3800lbs of sacs with 1 tsunami...I really need to replace my pumps! The originals are the yellow 750s w/ 3/4" hose. I wanna put in tsunami 1200s with 1" line. Also originally it has the pickups from the transom under the platform. I was going to take out the 3/4" thru-hulls and install 1" thru-hulls and run my intakes from the back still. Do you guys think this will be an issue compared to running it from the bottom? I am trying to minimize the cutting/filling of holes as much as possible here!
