Run your livewell on Auto, recirculate does just that. It doesn’t pump fresh water into the livewell. Just be careful if your fishing all day without running the big motor to recharge the battery, you may end up dead in the water.
The switch by the console on your boat may be stuck if your livewell is draining in the “Auto” setting. It could be stuck on empty instead!
Just a few things to check next time on the water.
You also don’t need the divider, it limits the fish’s mobility within your livewell!
