Good To Know

Q: Should I replace the head bolts too? A: Many marine engine rebuilds call for new torque-to-yield head bolts alongside the gasket. Check your service manual for the recommended replacement interval.

Q: Do I need to machine the head surface? A: If the head or block deck is warped or pitted, resurfacing is needed for the gasket to seal properly. Have both surfaces checked before installation.

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