Sierra 18-2770 Exhaust Tube - Replaces Mercury Marine 32-807458T

The Sierra 18-2770 Exhaust Tube is a direct-fit replacement exhaust tube built to meet or exceed original equipment quality. It is manufactured to function as a drop-in equivalent for the original Mercury Marine exhaust tube it replaces, giving boat owners a reliable way to restore proper exhaust routing without sourcing a discontinued OEM part. The tube is round in shape with a white finish and uses a bolt-on installation, so it mounts using the existing hardware and mating surfaces on the engine's exhaust system. Each unit ships as a single tube, ready to install in place of the original component.

Sierra manufactures its marine parts to consistent quality standards so that fit, form, and function match what the boat came with from the factory. The 18-2770 Exhaust Tube carries the Sierra part number 18-2770 and is cross-referenced to Mercury Marine part 32-807458T, making it easy to identify as the correct replacement when the OEM number is all you have to go on. It is a straightforward maintenance item for boat owners replacing a cracked, corroded, or leaking exhaust tube.
