Sierra Exhaust Tube 18-2759, Replaces Mercruiser 53114A1, Fits MCM 120/140/160/165 In-Line 6 Cylinder Engines

The Sierra 18-2759 Exhaust Tube is a bolt-on replacement exhaust tube built for Mercruiser In-Line 6 Cylinder stern drive engines, including the MCM 120, 140, 160, and 165 models. It routes exhaust gases away from the engine as part of the exhaust water shutter and exhaust tube system, and is manufactured to meet or exceed the specifications of the original equipment part it replaces. The tube has a round shape and a white finish, and is designed for a direct bolt-on installation without modification to surrounding components.

Each package includes one exhaust tube. Sierra designs this part as a like-for-like replacement for OEM and other aftermarket exhaust tubes used on the same engine applications, and it is cross-referenced to GLM, Mallory, and Mercruiser part numbers for buyers replacing an existing tube. Because fitment is specific to certain MerCruiser In-Line 6 Cylinder engine models, buyers should confirm their engine model against the fitment list below before ordering.
