In deck Livewell issue

[Squido]

I am doing the same project right now in my 23'. I am going with a 500 gph in and a 500gph going out. I will regulate with the valves on the out side of the tank. I am going to put my pump out thru hull high off the waterline next to my bilge pump out. So I can see it running even when I am up on plane. If it stops running for some reason I can see it and I know to go look right away. If something is below the water line you might not catch it right away. I will post pics later. I will be installing pumps tonight.
