Specs At A Glance

Good To Know

Q: Does this gasket need any sealant during installation? A: Most multi-layer steel head gaskets install dry, but follow the service manual torque sequence and specs for your Yamaha 1800 engine.

Q: Should the head bolts be replaced at the same time? A: Check whether your engine uses torque-to-yield bolts, as those must be replaced whenever the head is removed.

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