Over the winter I added two thru hulls, five Tsunami 800 pumps and a pair of 750's from Wakemakers to the rear of my OBV. I removed the stock Rule pump, solenoid, and strainer. I cut the scooper off my stock intake and added check valves to all three intakes. Because of our wonderful cold Michigan weather, I wasn't able to try everything out until a couple weeks ago. Everything worked as planned except for the fact that the boat was way too light up front. I had a feeling this was going to happen based on other forum user's suggestions. Because of this, I will be placing another order to Wakemakers very soon. Once I get my new IBS installed and tested, I will post pics of all my ballast and switch mods. My plan is to get it done in a couple of weeks.
