there are some of those bubblers, and you can buy pre-packaged kits... but honestly, it's cheaper if you buy everything separate.
If your cooler has a drain in the bottom corner on a side, you can take that out and just put in a livewell pump. Then all you would need would be a drain. You can follow the livewell build off the home page for this to work.
The other thing to do (exactly like the home page build) is put a bilge pump in the bottom, and use that to recirculate the water and do the pump out. The only extra piece you would need would be another bilge pump to throw over the side of the boat to pump water in -OR- you can install a livewell pump at the transom to push water in to the livewell.
