For anyone wondering about the livewell setup, I have it down now with the drain line out the transom that attaches at the bottom thru hull fitting and the overflow drain at the top of the well goes out the side of the hull. Works flawlessly. You can even pull out the drain plug in the bottom hole and put the standpipe in for even more overflow protection like when pan fishing, I've had perch stick their head in the overflow hole before and stop it up, they can't do that to the standpipe with the screen over it.
Inside the lid you can see an addition I made, it's a SS 18" ruler for measuring fish before dropping in the well. Around here we have a bunch of size limits. A slot for largemouth bass, everything between 12 and 17" has to be thrown back. Smallmouth bass, you can only keep 1 fish over 14". Walleye in some bodies have to be over 16" with only 1 fish over 24". Crazy regs to remember.
Here's a closer look, it's attached with SS screws.
