A small but crucial component, the exhaust manifold gasket, often gets overlooked until a problem arises. The Sierra International 1899114 Exhaust Manifold Gasket For Yamaha 6/8 Hp is designed to seal the exhaust manifold to the cylinder head, preventing exhaust leaks in Yamaha 6 HP (1986-2000) and 8 HP (1984-2009) outboard engines.
