Description

When your SX190 1800 HO shows signs of wear like low compression or rough idle, it’s usually due to worn internal parts. This Yamaha SX190 1800 HO standard complete engine rebuild kit targets those common wear points with a matched set of components that work together.

Because this kit supplies all major rotating and timing parts along with seals and gaskets, you rebuild the engine as a complete system instead of fixing pieces one at a time. In addition, REV6 inspects each component before shipment so you install parts you can trust.

Rather than mixing parts from different sources, this full kit ensures proper fit and helps restore stronger power and smoother performance out on the water.

WHY THIS KIT MATTERS

Engines with worn pistons or bearings often lose compression, which can show up as weak throttle response or uneven idle. Because this complete rebuild kit brings matched parts for all major wear areas, it helps restore compression and engine smoothness in one coordinated service.

Also, replacing timing and sealing components at the same time means you build the engine back as a whole unit, which helps reduce the chance of repeat wear problems down the road.
