Description

If your 2013–2015 Yamaha 242 LTD S 1800 needs an oversize rebuild, this +.25mm engine rebuild kit is built to restore compression and long-term reliability. Whether you are correcting cylinder wear or completing a full refresh, this kit provides the critical components required for a proper rebuild.

Because Yamaha 1800 marine engines operate under sustained load, precision matters. For that reason, this +.25mm configuration supports correct piston-to-wall clearance when paired with proper machine work. In addition, every REV6 rebuild kit is backed by a 1-year warranty on parts, so you can install with confidence.
