Namura Technologies NW-10003-2 Piston Kit Oversized Sea-Doo Internal Engine Parts - 82.50mm 0.50mm

The Namura Technologies NW-10003-2 piston kit is a high-performance replacement for Sea-Doo personal watercraft engines, featuring a +0.50mm oversized bore to 82.50mm. This complete kit includes everything needed for a professional rebuild: a precision-wrapped piston, OEM-quality ring set in a protective box, wrist pin, and circlips.

Advanced Piston Features:

• MOS2 Coated Skirts: Rolled-on Teflon/Molybdenum coating provides a bond 10 times stronger than spray-on alternatives, delivering superior heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Heads: Precision-machined surface reflects combustion heat and minimizes carbon buildup while potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Advanced anodizing process increases heat resistance and makes pistons 75% stronger than non-anodized alternatives for extended durability
• Hypereutectic Casting: Higher silicon content reduces thermal expansion rates, increases wear resistance, and withstands elevated cylinder temperatures for reliable performance

OE-Spec Gaskets Included: All Namura gaskets are manufactured to original equipment specifications, eliminating trimming and fitment issues. Materials are selected for superior resistance to temperature, oil, fuel, and coolant, and tested to ASTM standards to meet or exceed OE performance.

Ideal for rebuilding worn engines or increasing displacement in Sea-Doo watercraft applications requiring an 82.50mm bore diameter.
