Warranty Protection

Every Yamaha AR 190 rebuild comes backed by our Premium 1-Year Warranty. For maximum peace of mind, upgrade to our Platinum 2-Year No-Fault Warranty—designed to keep you covered no matter what.

Rebuild Process

At REV6, we completely disassemble, inspect, and upgrade each engine. Weak OEM points are eliminated and replaced with precision-machined components that meet or exceed factory standards. The result is an AR 190 engine that runs stronger, lasts longer, and delivers better reliability on the water.

This Yamaha AR 190 1800 is sold as a Build Core Engine. You’ll send us your rebuildable core, and our expert technicians will restore it using strict REV6 standards. If you’re unsure about core eligibility, visit our Help Center or reach out to us directly.
