I'm looking at buying a moomba outback and have a few questions.

1) how much weight is the gravity 1 system?

2) because the ballast is under the rear seat(I think) than could I plumb in a 750# bag into the rear locker for wake surfing? Into all the factory system.

I dont need a huge wave just surfable. I do like direct drive so I want to stick with
this boat, I also use our boat for wakeboarding and could either empty the fat sac or just leave it in while boarding.

Your guys thoughts?
