Namura Technologies Piston Kit Standard Bore Sea-Doo PWC Internal Engine Parts

The Namura Technologies standard bore piston kit for Sea-Doo personal watercraft (PWC) is a replacement piston kit for rebuilding a two-stroke engine's top end. It restores performance lost to wear, and it costs less than replacing the whole cylinder. Namura sizes each kit for a specific model and bore.

Key Features:

• Hyper-eutectic cast construction: The higher silicon content lowers the expansion rate and adds wear resistance.
• Machined smooth piston heads: They reflect combustion heat and reduce carbon buildup.
• Anodized domes: They add heat resistance and durability.
• MoS2-coated skirts: They improve heat transfer and reduce friction. This helps prevent cold seizures.
• Rings, wrist pin and circlips: Each kit is built around a piston, OEM-quality piston rings, a wrist pin and circlips.
• Standard bore sizing: The kits fit engines whose cylinders are still within standard bore specification. Oversize versions are sold separately for worn cylinders.

Namura Technologies offers OEM-quality pistons and rings at a lower price than many alternatives. Measure your cylinder bore before ordering to confirm the standard bore size is correct for your engine.
