I have a Bullet 22SF flats boat. Coming from a freshwater bass boat i have had trouble keeping water in the livewell. It fills up when i run with the intakes, but drains out when i stop. Kills fish this way obviously. Does a person really have to lie down and reach into the rear compartment and close the valves every single time you stop to fish? Or is there something im missing? Unable to find a good example of how to operate step by step when keeping fish in the well.
