Description

This Yamaha SX240 1800 HO STD engine rebuild kit is built for 2013–2015 jet boat engines that need standard internal components replaced during a rebuild. It includes key timing, piston, gasket, and bearing parts commonly refreshed in service.

Because these parts are selected for standard bore applications, they fit proper clearances without oversize machining. In addition, REV6 inspects each component before shipment to help ensure fit and quality.
