After a couple years of fishing this rig, I thought I would get around to adding a couple more options. My intentions were to have have done this some time ago, but I've been putting it off. Since I was going to be adding a new sonar unit, I thought I would get myself in gear and add some "central air". No, it won't keep you cool on those hot summer days, but it will keep those minnows aerated without a person having to listen to the hammering of the air pump the whole time you fish. Here is the start, and I'll add other pictures as I go along. It is simply running air lines to the front and rear of the boat and adding a 12 volt dual output aerator under the console. Here is the console, and sonar wiring ripped out getting ready to make the additions and changes.
Here is the brass air fitting for the front mounted on the front switch panel.
