Live Well 23 SF I/O

[keith]

I am trying to work out a live well in my Seacraft. I have a 23' SF I/O and behind the fuel tank there is a bin with a thru hull in it. It is probably 10 gallons or so. I'm debating to use that tank or the smaller ones on the transom. The transom boxes have a drain going out of the transom. They are pretty small, maybe 3 gallons.
To use the box below deck I need to have a bilge pump inside to pump out and a pump to go in. I was thinking of a combo washdown/baitwell pump.
Does anyone else have this box in their boat? I don't see it on the diagram on this site.
