2 ways. First is the aireation (spelling?) method which recirculates the water in the well adding oxygen via sprayers into the water. For this you would have a pump mounted in the tank with a discharge bar with lots of small holes in it. The pump sucks up the wate and puts it back via the bar with the holes, kinda like a fishtank. Second way is sea water in, sea water out. Here you have a pump mounted to the bottom of your boat with a sealed thru hull fitting it draws the water in from and pumps it into the livewell. The water will rise to a certin level and be directed overboard thru a sealed thru hull fitting. This way keeps constant "fresh" water in the tank.

If it's going to be a baitwell, I would strongly recommend the second way described above by Art, this will keep the water cooler, and will keep the bait lively alot longer then a recirculated baitwell.

You can go to 'Sur-Flow" bait pumps site. They give lots of information including size of pump related to the size of your live-well and the size of drain plumbing needed, which is the most common mistake made by manufacturers and DIY's. They also provide diagrams for simple instillations.

Make sure you read the part about the drain.Your pump is sending water into the live-well under pressure so the discharge has to be much bigger than the inlet to gravity drain the water. The drain outlet and hose should be 3 times the diameter of the inlet hose. Basically a 3/4" inlet hose requires a 1 1/4" discharge or drain hose.

You can always upgrade the pump, inlet hoses and that sort of stuff, but you only want to install the drain plumbing one time.

Always go with a larger pump, then gate the live aft of it into the tank so you can adjust your flow. A livewell system should have the flow to fill the tank in 7-8 minutes from dry. Any faster, you wear out the bait, any slower- red noses (lack of oxygen).

Look also at the Flow-Rite web site, http://www.flow-rite.com/

With their system, you can use one hull penetration for both pump feed and livewell drain. I'm using it on the livewell on my new Tolman Jumbo.
