Flow-through in deck Livewell on a 20?
 

Thinking about plumbing mine with a 3/4" scoop & seacock on the intake. 1 1/2" rear facing scoop or thru-hull and wedge, seacock for the overflow. I don't really want to go through the transom with any thruhull. I don't forsee any flow problems. Anyone have their's plumbed this way.
