Description

If your 2013–2015 Yamaha 242 LTD 1800 requires a larger oversize correction, this +.50mm engine rebuild kit delivers the components needed to restore compression and reliability. Whether you are correcting heavy cylinder wear or completing a full rebuild, this configuration supports proper machining and long-term performance.

Because marine 1800 engines operate under sustained RPM and load, precision fitment matters. Therefore, the +.50mm piston setup allows proper clearance when matched with correct machine work. In addition, every REV6 rebuild kit includes a 1-year warranty on parts, so you can install with confidence and get back on the water sooner.
