( Manufacturer Part Number: 5XC-11631-00-00 ), ( Part Type: Piston )
The Yamaha 5xc-11631-00-00 piston is a high-performance component designed for use in Yamaha outboard engines. This standard piston boasts several advanced features that contribute to improved engine efficiency, durability, and power output.
The piston is made of forged aluminum, a material known for its strength and lightweight properties. This ensures that the piston can withstand the rigors of prolonged use, even in the most demanding marine environments. The top ring groove diameter measures 51.7mm, and the compression height is 33.0mm, making it a perfect fit for specific Yamaha outboard applications.
One of the most notable features of this piston is its optimized piston crown design. The crown shape is designed to enhance combustion efficiency, reduce emissions, and improve fuel economy. The piston also incorporates a compression ratio of 12.0:1, which maximizes power output and engine performance.
The piston ring package is another area where the Yamaha 5xc-11631-00-00 stands out. This piston uses a multi-ring design comprised of a compression ring, an oil control ring, and a skirt oil scraper ring. The rings are precision machined to ensure a perfect fit and optimal function. The oil control ring minimizes the loss of engine oil during combustion, while the skirt oil scraper ring keeps the piston skirt clean, thus reducing the risk of cylinder scuffing.
Additionally, the piston's skirt design features a flat bottom to promote optimal oil control and cylinder lubrication. Furthermore, this piston is designed to minimize frictional losses during operation, contributing to improved engine efficiency and power output.
In conclusion, the Yamaha 5xc-11631-00-00 piston is a top-quality component engineered to deliver superior performance, durability, and reliability in Yamaha outboard engines. Its cast-forged aluminum construction, optimized piston crown design, and advanced piston ring package make it an ideal choice for marine enthusiasts and professionals alike.
