Description

This Yamaha FX Cruiser HO 1800 Waverunner Master Engine Rebuild Kit (+.25mm) is designed for 2013–2015 models that require a light oversize piston during a full engine rebuild.

Because this kit uses +.25mm pistons, it is intended for engines with minor cylinder wear that have been properly measured and prepared. As a result, it allows you to restore internal clearances while retaining factory-style fit and function.
