Our Custom Built Hybrid Exhaust - Your Questions Answered

In this episode of Your Questions Answered, we're tackling some of the top questions you had about our latest project-building a custom hybrid exhaust system for our 78' aluminum trawler, Tangaroa. You asked how we cut the holes in the boat, how we connected stainless to aluminum, why we went with such a large exhaust pipe, and whether we're worried about galvanic corrosion. Blaine also shares his thoughts on how much asbestos is still on board (yep, it's an old boat), and we dig into the big question of how long we think Tangaroa will keep cruising. This video is packed with practical info for anyone repowering a boat, working with Cummins marine engines, or dealing with tricky exhaust design challenges. Whether you're wrenching on your own boat or just curious how we're turning two Cummins 6.7L truck engines into a reliable marine setup, you'll get the behind-the-scenes details here. If you missed the main exhaust build, be sure to check out From Dry Stack to Custom Hybrid Water-Cooled Exhaust next. #boatrefit #detroitdiesel #cummins ?
