Quicksilver 2 Inch Riser Kit - Emissions Control
The Quicksilver 8M0153670 is a genuine OEM 2-inch (51 mm) exhaust riser kit engineered specifically for Emissions Control (EC) exhaust manifolds used in MerCruiser stern drive applications. This kit is the factory-authorized replacement for a wide range of 2008 and newer MerCruiser engines, ensuring proper fitment and performance without compromise.
Designed to direct exhaust gases safely away from the engine compartment while managing water ingestion typical of marine exhaust systems, the riser kit is a critical component in maintaining engine health and longevity. Using a genuine OEM part ensures compatibility with the original exhaust manifold geometry and sealing surfaces, reducing the risk of exhaust leaks, corrosion-related failures, and water intrusion into the engine.
This part supersedes several earlier Mercury Marine part numbers, including 879288A25, 8M0094680, and 8M0104209, consolidating compatibility across engine generations. It is also cross-referenced as equivalent to Recmar Marine part MAR679.
