Chris, take a flashlight and put it in the livewell, and then look in the compartment that’s getting wet. On one of my boats, the top of the livewell/underdeck needed a little silicone around the inside top to seal it. The Auto setting just fills the livewell to where you’re seeing it, you fill it the rest of the way with either the “pump in” or Aerator. I lose a little water out of the overflow when I get up on plane, that may be the issue if you’re losing water after you fill it to the overflow, or run the aerator.
