Description
The WSM Complete Gasket Kit for Yamaha 1800 HO, SHO, and SVHO engines (08-25) delivers dependable sealing for high-performance four-stroke watercraft engines. When engines are pushed hard, even small gasket failures can cause big problems.

Whether performing preventative maintenance or a full rebuild, this kit simplifies the process by providing matched sealing components in one package.
