Mike,
no harm is providing your solution, sometimes it helps those that are still new, gain additional info.
I don't know how your Mobius is setup, but I have the ability to drain each rear tank seperate. If the boat is unbalanced, I just drian the side needs to be a bit lighter. Work just like your system, only I don't have to move anything.
Just thought I would share!
