Ballast pump problem

I just bought an 06 supra 24ssv. it was three bags (left right and front) They all fill up fine, but when i go to empty, the front and right empty all the way but the left side pumps out untill theres about 50% of the bag full. So i pulled the boat out, disconnected the bag and drained it by hand.Put the boat back in and try it agian, same thing. Filled them all the way up they all drained out completly except the right still had about half a bag full. Any ideas...its the gravity 3

Make sure your bag is in the compartment correctly. A lot of times the bags get twisted and the drain hole isn't directly on the bottom of the end of the bag. Just reposition the bag so that all the water can flow down to the drain pump.

Similiar thing on my 05 21V, reversed the connections and now all is good.
