Yamaha Motors 6J8-W0001-C2-00
Lower Unit Gasket Kit
Gearcase resealing is labor-intensive and leaks can allow water intrusion or oil loss, so reliability matters more than small material differences. The Yamaha genuine kit offers OEM-controlled fit, seal compounds, and the correct drain screw gaskets, reducing the risk of premature leaks and rework.
