Another in a series of things I am doing to my boat during the off season. This is on a 2003 Moomba Mobius LSV. During almost all of last summer I had a problem with my bags not being able to empty. To my knowledge, this is not the factory setup for the ballast system.

I have two separate pumps for removing the water from my bags and only one that pumps water in (underneath and probably cant be seen in these pics). The empty pumps merge the water at the PVC "T" and pump out of one hole in the hull. My plan is to remove the large PVC "T" in the center and drill a new hole in the hull and pump the bags out separately.
I am wondering what size hole I need to drill in the hull and what type fittings are necessary to seal up the hole?
