That doesn't always work Scott! I did that on my 170 it vanished! LOL The fish box drain hose came off the fitting on the fish box... The water was actually just going in to the bilge... and If I had take the boat out without the plug that the PoO had stuffed into the thru hull... well my 170 would have sank!
looks like my live well drain location…. my fish box one is smaller and located a little bit higher and forward of that one.
