Description

When cylinder wear goes beyond standard limits, reusing stock-size pistons is no longer enough. Instead, stepping up to an oversize piston restores proper sealing and compression. That is exactly where this +.25mm complete rebuild kit comes into play.

Because all components are matched for oversize use, this kit helps eliminate guesswork during assembly. At the same time, it reduces the risk of uneven wear, oil blow-by, or early failure after the rebuild.

Additionally, this package replaces all major rotating and timing components at once. As a result, the engine is rebuilt as a system rather than as individual parts.

WHY CHOOSE A +.25mm KIT

Over time, heat and load wear the cylinder walls. When that happens, oversize pistons restore proper clearance and ring seal. Therefore, this kit is ideal when a standard rebuild no longer makes sense.

Likewise, rebuilding with the correct oversize parts helps extend engine life and improves long-term reliability on the water.
