Looking at both a 98 outback and a 98 mobius. They don't have factory ballast. Has anyone addded ballast under the floor or in the storage areas. I'd like to plumb it in and keep it off the boat floor so you don't have to step over or trip on it. Someone mentioned this might be a pain to put in, but I can't imagine it would be tha hard to plumb the ballast in. Unless the factory puts them in before the floors and it is not accessable anymore. Any feedback on past projects or the anatomy under the floor or in the storage areas would be appreciated.
