From Dry Stack to Custom Hybrid Water Cooled Exhaust

We've had enough of the soot, smell, and smoke. In this episode, we rip out our old dry stack exhaust system and start fresh-because let's face it, the exhaust setup that worked for our Detroit Diesel 12V71s just wasn't going to cut it for the new Cummins 6.7s. Blaine spent months designing a new solution that would work with our repower, be easier to maintain, and not leave our deck (or our feet) covered in black soot. The result? A custom-built, hybrid water-cooled exhaust. It's not fully dry, not fully wet-just the right blend to keep things running smooth and clean without sacrificing performance. If you're repowering a boat, upgrading your marine exhaust, or just curious how to deal with exhaust on a liveaboard, this video dives deep into the design and fabrication process. We show you what we built, why we built it, and how it fits into our engine room setup aboard our 78' aluminum trawler. Whether you're a diesel guy, a boat builder, or just like watching a good DIY project come together, this one's worth your time. #Cummins #BoatRefit #MarineExhaust ?
