Good To Know

Q: Is this an original Yamaha part? A: This is an aftermarket exhaust manifold gasket made to fit the listed Yamaha 1800 applications, so it is not an original Yamaha product. Confirm your model and year before ordering.

Q: Should this gasket be replaced whenever the manifold comes off? A: Exhaust manifold gaskets are generally single-use, so replacing it after removing the manifold helps prevent leaks. This gasket is a direct fit for the listed Yamaha 1800 models.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
