I'm not sure about your boat but I have a 1999 conquest 23 so maybe its similar.

In the floor I have a fish box. It has a drain plug for when I am out of the water and there is a pump that pumps the water overboard when I am in the water.

For my livewell mine is also behind the seat. I have a black plastic tube that goes the drain hole and at the top of the +/- 12" tube is a screen. The live well fills and once it gets to the top of the tub it overflows into the tube and down the drain.
In the livewell compartment up underneath is a spout that the water comes out of. At the end of this spout is a screw in valve and that lets the water in. Mine doesn't have its own pump but instead uses the washdown pump. If the valve is open my washdown hose doesn't work. if the valve is closed the washdown hose works.

Again not sure how yours is but this might help.
