• Exhaust-manifold gasket set for late-style Siamese-port GM four-cylinder MerCruiser heads.
• Direct interchange for MerCruiser 27-99777A1; also Barr MC47-27-99777A1, GLM 39320 and Mallory 9-61406.
• Verify serial number and cylinder-head port configuration because earlier 2.5/3.0L engines use different gasket arrangements.
• Designed as a direct marine-service replacement where the listed Sierra/OEM reference is specified.
• Compare the original part number, dimensions and assembly configuration before installation.

Fitment for marine engine and drive service parts can vary by model, serial number, drive/gearcase, cooling configuration and prior OEM supersessions. Compare the original OEM number and physical configuration before installation, and follow the applicable manufacturer service procedure and torque specifications.
