5 Reasons We Picked Cummins Over Detroit Diesel!

After years of running classic Detroit Diesel 12V71s on our 78' aluminum yacht, we finally made the call to repower—and we’re going with a pair of Cummins 6.7 marine engines. In this video, we break down the top 5 reasons why Cummins was the right choice for our boat repower project. From lower fuel consumption and better range, to worldwide parts availability and the simplicity of electronic common rail technology, these engines offered everything we were looking for. We also considered Yanmar, Volvo, CAT, and even Duramax truck engines—but nothing checked the boxes quite like the Cummins ISB 6.7. If you're into marine engine swaps, diesel engine comparisons, or you're just curious about what it takes to refit a yacht for long-range cruising, this one’s for you. We’re doing the work ourselves and sharing everything along the way—so whether you're a Cummins fan or a die-hard Detroit guy, you'll want to see this. #Cummins #DetroitDiesel #BoatRepower 👉 Want to go deeper into life onboard Tangaroa and get early access to every video from both of our channels?
