Rebuilt the Right Way

At REV6, one master technician assembles each engine, and another verifies the work. As a result, nothing leaves our shop unchecked. With over 50 years of combined powersports experience, our crew builds engines that outperform stock designs while giving you lasting confidence on the water.

Build Core Engine – What to Expect

This listing is for a Build Core Engine. That means it is not a drop-in motor. Instead, you send in a solid, rebuildable core, and we use it as the foundation for your remanufactured engine. During the rebuild, our team strips the core, machines it, and installs premium new and refurbished components for maximum reliability.

Because not every customer is familiar with core rules, we make it easy. Check our Help Center for clear guidelines, or reach out to our team before you order.
