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.
JDM Engines — Used & Remanufactured
Low-mileage JDM imports sourced directly from Japan. Every engine is compression-tested, leak-tested, and visually inspected before shipping. From the 2JZ-GTE and RB26DETT to dependable D-series and EJ platforms — the heart your build deserves.
Transmissions — Used & Remanufactured
Manual and automatic transmissions for nearly every JDM platform. Gearsets, synchros, seals, valve bodies, and solenoids all inspected — so you get smooth shifting that holds strong, whether it’s a drift car, daily, or weekend warrior.
Outboard Engines
Reliable outboards from trusted manufacturers. Repower a skiff or restore a classic boat with used and remanufactured motors — inspected, serviced, and ready to run.
Rigorous Inspection
Every unit passes a multi-point inspection before it’s listed — compression test, leak-down test, visual check for cracks or damage, and a spin test. If it doesn’t pass, it doesn’t ship.
Direct Japan Sourcing
We source directly from Japanese auctions, dismantlers, and surplus dealers — no middlemen, no inflated markups, no mystery inventory. What you see is exactly what we pulled from the container.
Fast Shipping
All inventory is stocked in our U.S. warehouse, and most orders ship within 1–3 business days. We use freight carriers who know how to handle heavy automotive parts, so your order arrives intact.
Warranty Coverage
Every engine and transmission comes with a standard warranty, with upgrade options available at checkout for extra peace of mind. We stand behind what we sell because we inspect what we sell.
Expert Support
Our team lives and breathes JDM. Have a compatibility question? We’ll give you a straight answer — even if that means admitting we don’t carry what you need. We’d rather lose a sale than sell you the wrong part.
