Our Story: Crankshaft Co.

At Crankshaft Co, we specialize in supplying high-quality outboard motors, JDM engines, and transmissions — both used and remanufactured — for enthusiasts who refuse to compromise on performance.

We started with a simple belief: the right engine shouldn’t feel like a gamble.

For many builders and boat owners, buying an engine or transmission raises questions you shouldn’t have to navigate alone. Will it run strong? Is it worth the money? Is it right for my setup? What am I not being told? We understand these concerns because we’ve lived them. Whether you’re assembling a drift car, rebuilding a daily driver, or repowering a boat for the season, you need more than torque — you need confidence.

That’s where our story begins — with people who know the garage and the water equally well, and with a shop culture built on honesty, careful sourcing, and guidance you can genuinely use.
