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.\u003c\/p\u003e\u003cp\u003eSierra 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-2770\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Type:\u003c\/strong\u003e Bolt-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.99 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282101084\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 32-807458T\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 32-807458T\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2770 Exhaust Tube replace?\u003c\/strong\u003e It replaces Mercury Marine part number 32-807458T, so any boat calling for that original equipment exhaust tube can use the Sierra 18-2770 instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2770 a genuine OEM part or an aftermarket replacement?\u003c\/strong\u003e The Sierra 18-2770 is an aftermarket part manufactured by Sierra to meet or exceed the quality of the original Mercury Marine 32-807458T exhaust tube it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2770 Exhaust Tube weigh?\u003c\/strong\u003e The Sierra 18-2770 Exhaust Tube weighs 0.99 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-2770 Exhaust Tube?\u003c\/strong\u003e It is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is this exhaust tube?\u003c\/strong\u003e The Sierra 18-2770 has a round shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the Sierra 18-2770 Exhaust Tube installed?\u003c\/strong\u003e It uses a bolt-on installation type, mounting in place of the original Mercury Marine 32-807458T tube using the existing engine hardware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many exhaust tubes come in the package?\u003c\/strong\u003e One Sierra 18-2770 Exhaust Tube is included per unit purchased.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the Sierra 18-2770 perform the same as the original Mercury Marine part?\u003c\/strong\u003e Yes.
