The Engineered Marine Products 27-00642 is a replacement cylinder head gasket designed for the starboard (right) side cylinder bank on Yamaha 4-stroke V6 outboard engines. This gasket provides a critical combustion and coolant seal between the cylinder head and the engine block, helping maintain proper compression, prevent coolant intrusion, and ensure reliable engine performance.
Engineered to meet OEM fit and function specifications, this starboard head gasket is a direct replacement for worn or damaged original equipment. It is side-specific and not interchangeable with the port-side cylinder head gasket (27-00643).

- OEM-spec replacement cylinder head gasket for the starboard cylinder bank
- Precision-engineered for a correct fit and proper seal
- Designed for Yamaha 4-stroke V6 outboard applications
