Thanks for the replies guys –

Capt Chuck – I appreciate the “center keel” option but I don’t really want to cut my keel stringer out – if anything I plan on extending it up the transom some for extra support in the middle.

Warthog – the infamous “NASA” hatch
That is why I picked that wide hatch for the vertical transom surface. It's about the widest one I have found and it hinges 180 degrees (all the way up out of the way) - I plan on moving my trim tab pump and some other goodies to the inside of the transom.

I wish I had the Kodiak model tank with the bottom feed and drain.. I would probably mount it in a permanent position behind my leaning post. I thought about using a PVC 90 degree elbow to direct the overflow down somehow and route back (another 90 degrees) to a to a large seacock drain?

I could keep it removable with only a pipe or hose to step over when the live well is in the boat and attach it to a hose barb or some sort of quick disconnect (as you suggested). I'm gonna have to cipher on this a little more.

Worst case I might just have to come up with a new plan (i.e. bait well) altogether
