I am sure this has already been discussed, but I could not find a thread on it. Does anyone know how big the rear ballast tank is on the '03 Mobius LS?

I was reading the boat edition of Skiing magazine and the Mobius LS they tested had a ballast size of 750lbs. I assuming that meant 400lbs in the rear and 350lbs in the ski locker??? Does anyone know for sure?
