This gasket seals the upper section of the water pump housing to prevent leaks and maintain proper cooling water flow through the pump assembly. It is made of glass material, measures 0.25 inches thick, and is finished in black. Each Sierra gasket is manufactured to meet or exceed the specifications of the original equipment part it replaces, making it a reliable choice when servicing or rebuilding a water pump. Because gaskets degrade with heat cycling and age, replacing the upper water pump gasket during any water pump service or impeller replacement helps ensure a proper seal and prevents coolant water leaks. This listing includes two gaskets per package, so a spare is on hand for future service or for pumps requiring more than one gasket.\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 18-2824-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Upper Water Pump Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 2 gaskets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Thickness:\u003c\/strong\u003e 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282163310\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury marine applications\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e27-32770\u003c\/li\u003e\n\u003cli\u003e27-19551\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2824-9 gasket fit?\u003c\/strong\u003e The Sierra 18-2824-9 upper water pump gasket is designed for Mercury marine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in this package?\u003c\/strong\u003e This package includes 2 gaskets, as the Sierra 18-2824-9 is sold in a pack of 2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-2824-9 replace?\u003c\/strong\u003e It replaces Mercury OEM numbers 27-32770 and 27-19551.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the gasket made from?\u003c\/strong\u003e Glass is the material used for the Sierra 18-2824-9 upper water pump gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow thick is the gasket?\u003c\/strong\u003e 0.25 inches is the thickness of the Sierra 18-2824-9 gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-2824-9 gasket?\u003c\/strong\u003e Black is the color of this gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the gasket weigh?\u003c\/strong\u003e The Sierra 18-2824-9 upper water pump gasket weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-2824-9 is a Sierra-branded gasket manufactured to meet or exceed the specifications of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should the upper water pump gasket be replaced?\u003c\/strong\u003e Replacing the upper water pump gasket is recommended during water pump service or impeller replacement to ensure a proper seal and prevent coolant water leaks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a lower water pump gasket available separately?\u003c\/strong\u003e Yes, the upper water pump gasket (18-2824-9) is a distinct part from a lower water pump gasket, so buyers should confirm which position they need before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2824-9?\u003c\/strong\u003e The UPC for this pack of 2 upper water pump gaskets is 808282163310.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988130083035,"sku":"SIE-18-2824-9","price":3.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2824-9__48151.1737896784.500.750.jpg?v=1785188602","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2824-9-upper-water-pump-gasket-2-pack-for-mercury-40-50-70-hp-outboards-replaces-27-32771","provider":"Good Vibes Marina","version":"1.0","type":"link"}
