Warranty Coverage

Every engine includes a 1-Year Warranty as standard. For extra confidence, upgrade to our Platinum 2-Year No-Fault Warranty and enjoy industry-leading coverage that goes above and beyond. Learn more in our warranty policy.

Rebuilt the Right Way

REV6 engines aren’t rushed builds. Each unit is hand-assembled by a master technician, then double-checked for accuracy and performance. With over 50 years of combined powersports knowledge, our team ensures your engine is better than OEM and ready for years on the water.

Build Core Engine – What to Expect

This is a Build Core Engine, not a plug-and-play replacement. A solid, rebuildable core is required. Your core is stripped, machined, and rebuilt using premium components to factory or better specifications.

Not sure about your core? Our Help Center explains requirements, or you can contact us for assistance before ordering.
