I have a 99 R93. My livewell will not fill up all the way. I put it on "empty" and it fills up about 4-5 inches. I move the lever to "Auto" and turn pumps on and they just run , but the water level never gets any higher. I believe both pumps are running because I get water out of both sides. When I put it on "Recirculate" it does hold the water in the well until I hit empty. Do I need to look at the Valve, Pump, or check valve? Thanks
