As I stated in the beginning, I needed more weight up front. The only problem was that I was running out of room. I carry 2 wakeboards, 1 kneeboard, 1 slalom ski, 1 pair of junior combo skis, 1 pair of adult combo skis, and soon a surfboard. I am getting new racks so that I can have a wakeboard and kneeboard on one side, and a wakeboard and surfboard on the other. I do not want to change to a storage bimini, and I do not want 5 skis hanging on my tower, so I made a decision. I removed the stock ballast bag and drain pump from the center ski locker. All 5 skis fit in there nicely. I then installed a new IBS with a provision to reuse the stock ski locker bag on top of the floor. I added a new length of hose to the center bag fill pump. It follows all the wiring across the fuel tank and up through the floor. I was worried about kinking the hose, so I added a fill port to the side of the IBS bag on the driver side using a white, 90 degree, 3/4" Seachoice thru hull part number 18131.



I then installed new Tsunami 800 drain pumps on each leg. The driver side drains out the original center sac drain on the driver side. The passenger side drains out a newly installed thru hull on the passenger side. I wired them both into the center fill/drain switch.





Here is the IBS full. You can also see the vent which runs to the passenger side and vents out another newly installed thru hull next to the drain.
