Quicksilver 860246A15 Exhaust Manifold for MerCruiser V8 Engines (GM)

The Quicksilver exhaust manifold 860246A15 is a high-quality original replacement exhaust manifold for selected MerCruiser V8 Sterndrive and inboard engines manufactured by General Motors (GM). It can be used on both the port and starboard sides (left or right) and is suitable for engines with 305, 350 and 377 cid displacement from the model years 1983 to 2002.

Manufactured from solid cast iron, the exhaust manifold is specially coated to reliably protect both the internal coolant passages and the external surfaces from corrosion. Thanks to the hot-dip process and powder coating, it is ideal for use in freshwater and saltwater. The matching gasket is included, making replacement easier and ensuring secure installation.
