Description

This Yamaha AR 190 HO 1800 master engine rebuild kit is built for 2013–2015 jet boat models using standard bore pistons. It includes the core internal components needed to complete a full engine rebuild with proper fit and clearances.

First, this kit focuses on the parts that matter most during assembly. Instead of mixing mismatched components, you get a complete, coordinated set designed to work together. As a result, builders can assemble with confidence and avoid common rebuild errors.

Next, every component meets OEM specifications for size, material, and fit. Because accuracy matters, REV6 selects parts that support consistent oil control, correct timing alignment, and long-term reliability.
