As the impeller wears, cooling flow drops and the engine runs hotter, so a fresh impeller at the recommended service interval keeps the water pump delivering full flow to the powerhead. This impeller is engineered to meet or exceed the performance of the original equipment part it replaces, and it is built to Sierra's standard for withstanding the demands of high-horsepower engines operating in the harsh marine environment.\u003c\/p\u003e\u003cp\u003eThe 18-8920 is designed for Mercury 8 (8B models) and Mercury 98 (98B model) outboards, including the 8 4-Stroke (All) and 98 4-Stroke (All) applications. Installing the correct impeller for your specific model is important, since an impeller sized or shaped for a different water pump housing will not seal or pump correctly. This is a single impeller, sold as one item, intended as a service replacement part for the outboard's water pump housing.\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 18-8920\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282256890\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282256890\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard Water Pumps \u0026amp; Impellers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 8 (8B models)\u003c\/li\u003e\n\u003cli\u003eMercury 98 (98B model)\u003c\/li\u003e\n\u003cli\u003eMercury 8 4-Stroke (All)\u003c\/li\u003e\n\u003cli\u003eMercury 98 4-Stroke (All)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-8920 impeller fit?\u003c\/strong\u003e The 18-8920 is built for Mercury 8 (8B models) and Mercury 98 (98B model) outboards, including the 8 4-Stroke (All) and 98 4-Stroke (All) applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-8920 impeller?\u003c\/strong\u003e It is white, which is the standard color for this Sierra impeller.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-8920 weigh?\u003c\/strong\u003e The Sierra 18-8920 impeller weighs 0.06 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many impellers come in one order?\u003c\/strong\u003e One order of the 18-8920 includes a single impeller (number of items: 1).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-8920 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-8920 is a Sierra replacement impeller engineered to meet or exceed the performance of the original equipment part it replaces on Mercury 8 (8B) and 98 (98B) outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-8920 fit a 4-stroke Mercury outboard?\u003c\/strong\u003e Yes, the 18-8920 covers the 8 4-Stroke (All) and 98 4-Stroke (All) Mercury models in addition to the 8B and 98B models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-8920 impeller?\u003c\/strong\u003e The UPC for the Sierra 18-8920 water pump impeller is 808282256890.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the 18-8920?\u003c\/strong\u003e The 18-8920 is a water pump impeller listed under Mercury Outboard Water Pumps \u0026amp; Impellers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-8920 come with a warranty?\u003c\/strong\u003e The Sierra 18-8920 impeller is covered under Sierra's standard customer satisfaction warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does an outboard need a new impeller?\u003c\/strong\u003e A worn water pump impeller reduces raw water flow to the engine's cooling system, and the Sierra 18-8920 is a direct replacement impeller to restore that flow on compatible Mercury 8B and 98B outboards.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988436103387,"sku":"SIE-18-8920","price":12.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-8920_lg__41738.1558132310.500.750.jpg?v=1785188200","url":"https:\/\/www.goodvibesmarina.com\/products\/water-pump-impeller-for-tohatsu-nissan-mercury-8-9-8-hp-outboards-replaces-oem-3b2650211m-sierra-18-8920","provider":"Good Vibes Marina","version":"1.0","type":"link"}
