Description

When your Yamaha SX190 1800 HO engine remains within factory bore limits, a standard-size rebuild is the correct approach. This master engine rebuild kit refreshes every critical internal system while maintaining original tolerances.

Because all rotating, timing, and valvetrain components are addressed together, the rebuild delivers consistent compression, stable oil control, and smooth engine operation. As a result, reliability improves without unnecessary machining.

Every component is selected to work as a complete system and is backed by a 1-year REV6 parts warranty for added confidence during assembly.
