I fish tournaments and in the summer would like a recirculating capability on my two livewells. (Front and Back) Does anyone have any ideas how to do this? My boat only has incoming aeration water, too warm. Would like to use ice and keep the water temperature cooler for the smallies we catch this time of year. Can't get to the livewell in the back because the gas tank is in the way and side storage compartments don't come out. Any ideas will be greatly appreciated. Thanks.
