Quicksilver 8M0164159 Dry Joint Manifold & Elbow Conversion Kit for MerCruiser V8

The Quicksilver 8M0164159 is a complete Dry Joint Exhaust Manifold and Elbow Conversion Kit designed for MerCruiser small block V8 engines. This genuine Mercury Marine OEM kit provides everything needed to upgrade an older wet joint exhaust system to the more modern and reliable dry joint configuration.

The dry joint exhaust design eliminates the water-cooled joint between the manifold and elbow, reducing a common failure point found in traditional wet joint systems. This upgrade improves durability and long-term reliability for sterndrive and inboard marine applications.

Kit Application:

• Converts MCM small block V8 engines with standard cooling and no risers
• Upgrades wet joint exhaust manifolds with 4 in. O.D. center-rise 7-degree exhaust elbows to dry joint manifolds and elbows
• Fits GM small block engines (305, 350 & 377 CID)
• Compatible with 1987–2004 MCM sterndrive engines (s/n 0W309999 and below)
• Compatible with 1987–2001 MIE inboard engines (s/n 0M316999 and below)

Important Notes:

• Engines equipped with freshwater (closed) cooling systems and/or risers may require additional exhaust elbow gaskets ordered separately

• Backed by Mercury Marine's 1-year factory warranty against defects in materials and workmanship

Upgrade your MerCruiser V8's exhaust system with confidence using this complete OEM Quicksilver conversion kit — the direct factory solution for transitioning to the improved dry joint exhaust platform.
