center bilge showing the livewell pump and center venturi thru hull drain and bronze T-handle plug. The venturi drain will drain while underway and there is an additional 1100 gph Auto Rule bilge pump as backup. Counting the pump in the Mega compartment I have four bilge pumps and a portable 4000gph with battery clips, I can use in an emergency. The washdown Flo-Jet pump will for in the rear starboard compartment with the Jackplate pump. Oh yeah.....this whole area drains to the rear bilge area too. Don't want any trapped water sloshing around.
