FASWORX Exhaust Manifold for MerCruiser 5.0L, 5.7L, 6.2L GM V8 (305/350/377), Fits Years 1983 to Early 2002 Wet Joint, Replaces Part numbers 860246A15, 860246Q11, 18-1953

This FASWORX exhaust manifold is engineered for MerCruiser GM small block V8 engines equipped with traditional wet-joint exhaust systems. It is designed for 5.0L (305), 5.7L (350), and 6.2L (377) applications. Wet-joint exhaust systems route cooling water through the manifold-to-elbow connection using a gasketed joint. This is NOT compatible with later dry-joint systems and must not be mixed with dry-joint components. This replacement is intended for engines experiencing internal corrosion, restricted water flow, exhaust leakage, or general age-related deterioration common in marine exhaust components. Always confirm your existing configuration by OEM part number and joint style prior to installation.
