Wanted a bait well big enough to keep bluegills alive in for cat fishing , minnows alive in for slow trolling,or shad alive in for hydrids....
Went online and found a Moeller round 24 gallon tank with round lid.Used 1 1/4" thru-hull mounted from inside tank with hose barb pointing out.Used bilge pump intake plastic screen under thru hull to keep minnows from coming out of tank(it is removable ). Used rubatex (K-Flex) industrial insulation sheeting and cement to insulate entire tank. Spray painted white with Plastic rated paint to go from black to white outer color .Installed plastic ball valve in drain line over transom.Mounted a Power bubbles aerator to top of tank after sealing aerator from water exposure.....Can remove install from either of my boats with 4 screws....Works just fine for me.....
In addition,I used another type intake screen and mounted on suction side of a bilge pump connected to a 8" 3/4" hose to pump discharge for pumping water from lake to live well and can open the ball valve to drain the tank on big boat . On jon boat I use pump to remove water from live well and refill.Mounted an SS eye bolt inside tank to connect brass dog snap and rope connected to hose/pump assembly.Don't have to hold and will not drop into lake....
