Sierra Exhaust Tube, 3 Inch I.D., Replaces 32-90949T, Fits MerCruiser 470/485 898 260 Engines

This Sierra Exhaust Tube is a direct-fit replacement exhaust tube built for MerCruiser stern drive engines that route exhaust through a 3 inch inside diameter tube. It is designed to install in place of the original equipment exhaust tube, carrying hot exhaust gases away from the engine as part of the exhaust and water shutter system. The tube has a round profile and a white finish, and each package contains one exhaust tube.

This part is intended for MerCruiser MCM 470/485, 185, 205, 898, 228, and 260 engines. It is a direct cross-reference for Mercury Marine 32-90949 and 32-90949T exhaust tubes, so it installs using the same mounting points and bolt pattern as the original part it replaces. Sierra manufactures its marine parts to meet or exceed the specifications of the original equipment part, and this exhaust tube is backed by Sierra's standard limited warranty.
