[ULTIMATE QUALITY & LEAK PROTECTION] Every manifold and riser undergoes rigorous pressure leak testing and features 100% machined flat mating surfaces to ensure a perfect seal. We include premium stainless steel graphite gaskets to provide superior heat resistance and protect your engine.
[PRECISE 1983 - EARLY 2002 FITMENT] Engineered specifically for MerCruiser Small Block V8 (5.0, 5.7, 6.2) engines. This is designed for "Wet Joint" center-rise exhaust systems.
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.
