Good To Know

Q: Should head bolts be replaced at the same time? A: Many marine engine head bolts are torque-to-yield, so replacing them along with the gasket is a common practice to maintain proper clamping force. Follow the service manual torque sequence during installation.

Q: Is this an original Yamaha gasket? A: This is an aftermarket head gasket for Yamaha applications, not an original brand item, and it cross-references OEM part number 6JC-11181-00-00. Confirm the number matches your engine before ordering.

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