I have a 1996 461. The live wells have fill and empty with recirculate in the middle. I have always ran them on fill. Now when I get on plane my wells almost empty. They also aren't filling up as much as I would like. I just checked and when I go from empty to fill the linkages do expand. Anybody got any quick fixes? I guess something is wore out or keeping the valves from shutting all the way. Any help would be appreciated.
