Ok, I'm getting tired of filling up my cooler with a bucket every time I want to use it, not to mention heaving it over the gunwale at the end of the day to dump it out.

The cooler I have is and Igloo Quick and Cool 100qt and I'm trying to think of a way to pump water in and out of it as effectively as possible. I like the looks of the ' Rule Transom Mount Livewell/Bilge Pump' on Cabelas because it mounts to the transom. I have already owned one leaky aluminum boat and I have no interest in drilling 3/4" holes in my boat below the water line. The problem is, how to pump water back out of the livewell when you want to add more? If there are two way bilge pumps, I haven't been able to find one. My ideal scenario would be to have a transom mount bilge pump that I can attach/detach easily. Then run a switch to the bow to turn it on/off and control the direction of the water. If I could flip a switch, fill it up, then when I want to replace some of the water, flip the switch in reverse for a bit, then fill it back up, that would be totally ideal.

I've thought of running two pumps, one to fill it and one to empty it, but I don't really want to have to buy two of them if I can avoid it. I have enough wires running around the boat as is :) Any thought on this? I'm sure someone has a great system out there and I would love to hear about it if you do.
