Description

Over many hours on the water, engine parts like pistons, bearings, and timing components wear down. As a result, compression drops and power can fade. This Yamaha SX240 1800 HO standard engine rebuild kit replaces those core items in one matched package so the engine can run strong again.

Because this kit includes all major rotating and sealing parts, you rebuild the engine as a complete system. In addition, REV6 inspects every component for fit and quality before shipment, so you get parts you can trust.

Instead of repairing individual pieces at different times, this full kit brings the key wear points back to spec together. That approach helps restore throttle response, idle quality, and overall reliability.

WHY THIS KIT MATTERS

Engines with worn pistons and bearings often lose compression and feel sluggish at mid-range or top end. Because this kit renews key wear items together, you help ensure more consistent power and smoother operation than replacing parts one at a time.
