Intake Gasket Set - .051 BBC Mercury Marine 1050

The Cometic Gaskets Intake Gasket Set for Big Block Chevy Mercury Marine 1050 (SKU CAGC5821-051, MPN C5821-051) is a precision-engineered intake manifold gasket designed specifically for Mercury 1050 big-block Chevy marine engines. This multi-layer steel gasket set features a nominal thickness of 0.051 inches and rectangular port dimensions of 1.85 x 2.5 inches, engineered to seal the critical junction between intake manifold and cylinder head where combustion pressures and fuel-air charge dynamics demand absolute integrity.

Cometic's multi-layer steel construction delivers superior sealing performance compared to conventional cork or composition gaskets, particularly in marine environments where salt air, constant thermal cycling, and sustained RPM loads accelerate gasket degradation. The 0.051-inch thickness is calibrated to maintain proper intake valve timing geometry and fuel distribution consistency while accommodating typical big-block Chevy port surface finishes. This gasket set arrives as a matched pair, ensuring port-to-port compression uniformity across both cylinder banks—critical for balanced fuel metering and predictable engine response under heavy load conditions typical of marine propulsion systems.

Operators performing intake manifold service, cylinder head work, or addressing intake leakage on Mercury 1050 installations will find this gasket set indispensable. Whether you're diagnosing stumbling under acceleration, fuel seepage around the intake baseplate, or conducting scheduled preventive maintenance in high-hour marine applications, this Cometic gasket set provides the precision fit and material durability required to restore original sealing performance. Weighing 1.51 lbs and measuring 5.1 x 0.5 x 22.95 inches, the set integrates seamlessly into standard intake manifold assemblies without modification.
