Yamaha AT1M/AT1MX CT1 Piston Ring Set (75mm, 3rd Oversize) for Yamaha Outboard Engines (Yamaha Part Number: 251-11601-30)

Description:

The Yamaha 251-11601-30 piston ring set is an essential replacement part designed specifically for Yamaha outboard engines requiring a 75mm piston diameter and a 3rd oversize piston ring. This set is suitable for various models of Yamaha outboard engines, including those used in small boats, personal watercraft, and industrial applications.

The piston rings in this set are meticulously engineered to provide superior sealing performance, ensuring optimal engine efficiency and reliability. These rings are manufactured from high-quality materials, ensuring a long service life and robustness against the harsh marine environment.

The set includes three piston rings: the compression ring, the oil control ring, and the skirt ring. The compression ring, which is the topmost ring, is responsible for sealing the combustion chamber and transmitting the engine's power. The oil control ring, situated just below the compression ring, restricts oil consumption by preventing oil from passing between the piston and the cylinder wall. Lastly, the skirt ring, located at the bottom of the piston, seals the piston to the cylinder wall and ensures proper piston-to-cylinder clearance.

Installing these piston rings is a crucial part of maintaining your Yamaha outboard engine's health. Properly installed piston rings ensure effective engine performance, minimize oil consumption, and prevent costly engine damage or failure. If you suspect that your engine's piston rings need replacement, it's essential to address the issue promptly to ensure continued reliable operation.

In summary, the Yamaha 251-11601-30 piston ring set is a high-quality replacement part designed for Yamaha outboard engines requiring a 75mm piston diameter and a 3rd oversize piston ring. This set ensures superior sealing performance, long service life, and robustness in the marine environment. By investing in this piston ring set, you're not only ensuring optimal engine performance but also preventing potential engine damage or failure.
