Our Marine Cooling System for Cummins Truck Engines Your Questions Answered

We're answering your questions about our custom marine cooling system for the Cummins 6.7 engines we installed in our 78' aluminum trawler, Tangaroa. From engine cooling circuits to seawater wear, this Q&A dives into the gritty details behind what it takes to adapt truck engines for marine duty. In this episode, Blaine tackles real viewer questions: Do we need a charge air cooler circuit? Can we still remove the starter with everything installed? Are we worried about seawater ruining our eBay heat exchangers? And yes-someone asked if we're finally getting a new welder. If you're into boat refits, DIY marine upgrades, or diesel engine swaps, this one's for you. We built this repower ourselves-every bracket, pipe, and elbow-so nothing is off-the-shelf. If you're planning your own marine engine swap or just love learning how things work, stick around. There's even a question of the week that made Blaine stop and rethink a few things. Don't forget to hit subscribe and join us every Sunday as we continue this epic repower project aboard Tangaroa. #Cummins #DetroitDiesel #BoatRefit ?
