Description

This Yamaha FX HO 1800 Waverunner Master Engine Rebuild Kit +.50mm is designed for 2013–2015 models that require an oversize piston rebuild. It includes the main internal components commonly replaced when restoring worn cylinders and rotating assemblies.

Because this kit uses matched +.50mm piston sizing, it supports engines that have been bored or require additional material cleanup. At the same time, all supporting components are selected to maintain proper clearances and reliable operation.
