Default live well factory plumbing

I'm trying to figure out how the plumbing for the stern livewell in my 1988 Welcraft 18' center console was originally run from the factory. The bottom of the livewell is above the water line. There are 3 holes in the livewell: one at the top that goes directly thru a thru hull fitting overboard, a second at the other end of the livewell, and one at the bottom center. What I don't understand is how would you drain the water out of this livewell and out of the boat? There is a thru hull fitting below the waterline on the transom that appears to be the intake. It had a in-line valve directly on the end of threads 5" away from the inside of the transom with an electric pump threaded directly into the other end. From there in just went to a hose and that hose was just laying loose under the deck when I bought the boat. It looks like I would have to have a second pump attached to the drain of the livewell in order to pump the water up and overboard. That doesn't really make sense to me. Anyway the live well is square shaped and small (8 gallons) so my idea is to just put a fitting in the drain hole with a hose running to my bilge. Then just let the livewell gravity drain and let the bilge pump send it overboard. Are there any problems with this idea ? I kind of doubt that a livewell of this size and shape is going to be of any practical use. I will probably use a removable round tub in front of the center console when I'm using live bait.

I have utilized the existing hole in the transom and installed a proper thru hull fitting, flange, and seacock. The old valve was seized in a half open position and without even reading the abyc standards I knew that having a pump supported like that was ridiculous.

Any ideas are welcome. Thanks in advance.

Seems like the drain at the bottom should be connected to a hose that leads the a thru hull. Use a stand pipe during use and pull it to let the water out. The hole on one end that goes overboard should be the overflow, the stand pipe would normally be about 1/2" +/- lower so the water would drain out of it before draining out of the overflow. The hole on the other side should be the livewell fill, with a hose coming from the intake/ livewell fill pump.

Yes that would make sense to me but the only other thru hull fitting in that area of the boat, besides the one I mentioned in my original post that appears to be an intake, is for a deck drain. I thought maybe what you do is run the pump backwards and that one thru hull is both intake and drain. That seems unlikely to me, but I have no idea how these boats were set up. Or maybe the livewell drain was T into the deck drain ? That would work by gravity but it seems like T into a deck drain is a bad idea. The livewell to me appears to have been installed at the factory because you would have to remove the cap from the hull to gain access to the fasteners.

I think a T into the deck drain would work fine if you want to go that route.
