Spring 2024: Our Most Ambitious DIY Boat Refit Ever!

From Old to Bold: Witness Our Cummins Repower Adventure!

Welcome to our exciting Cummins Repower journey!


We’re transforming our trusty aluminum boat with a complete engine overhaul, upgrading to powerful Cummins engines for better performance and efficiency.


This isn't just a simple swap; it's a full-scale adventure involving detailed tasks like fabricating new exhaust, rebuilding the fuel system and repitching the props. We also have to fabricate our own engine mounts and make our old 1969 throttles operate with an ECU!


Our videos take you behind the scenes, showing every step of this intricate process. Whether you’re a boat enthusiast or just love seeing how things work, these videos are packed with interesting and crazy things.


By subscribing to our channel, you’ll stay up-to-date with each phase of our project, and we love engaging with our audience, so feel free to leave comments – we try to answer every one.


Dive into our repower journey and join us as we complete this repower all by ourselves!
