Had boats previously with permanent live wells. One was dual aerated wells. Pump in, pump out, recirc, etc. On timers too.
a few things about permanent livewells. One they need to be cleaned fairly often. Two, they need to be able to plugged so you can use them for dry storage. Three, if you plumb pumps, use the correct hoses. Lots of people use garden hose and over time it gets hard & cracks. Sometimes you don't know until it's been turned on for a while and then you realize that the boat is filling up with water. Or if the drain/pump out, recirc leaks, it can leak water that way too.
I went back to a jon boat, open floor, with a cooler for a livewell. If I am using catch/release, I'll take it out and leave it in the garage. If I plan on keeping a few, I'll throw a couple bags of ice in it and just put the fish on ice immediately after catching them. They taste better, IMO, especially in the hot summer. To clean it, pull it out & clean it with garden hose. Easy. It just seems to be a better option for me as opposed to my old boat which had dual wells. One was used exclusively for for dry storage.....when it didn't leak. I hated cleaning them too. Always used a little clorox in a lot of water and never failed to get some on the carpet which would lighten up the color (it was dark blue). That whole deal was a pain in the butt. Seemed to have to work on it more than use it. New boat is super simple and when something goes wrong it's an easy fix....usually right there on the water.
