As the impeller wears, worn or cracked vanes can no longer maintain proper water flow through the cooling system, leading to overheating and potential engine damage; replacing it with the Sierra 18-3071 restores the pump's ability to draw and circulate cooling water at the correct volume. The impeller has a machined exterior finish and is manufactured to meet or exceed original equipment quality, giving it a direct fit and consistent performance in place of the factory part. It is sized to install into the Yamaha outboard water pump housing alongside the associated pump components, and it directly replaces Yamaha OEM part number 6E5-44352-01-00. This impeller is intended for routine water pump maintenance and rebuild kits on Yamaha 2-stroke outboard engines, and should be inspected and replaced as part of scheduled cooling system service to help prevent overheating-related failures.\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 18-3071\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Impeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 1.25 x 6 x 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999315236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha outboard 2-stroke water pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 6E5-44352-01-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha outboard water pumps (2-stroke)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e6E5-44352-01-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3071 impeller fit?\u003c\/strong\u003e The Sierra 18-3071 is designed for Yamaha outboard water pumps on 2-stroke engines, replacing the factory impeller in the pump housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3071 a direct OEM replacement?\u003c\/strong\u003e Yes, the Sierra 18-3071 directly replaces Yamaha OEM part number 6E5-44352-01-00 and is manufactured to meet or exceed original equipment quality.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the part number for this impeller?\u003c\/strong\u003e This impeller is Sierra part number 18-3071, the manufacturer part number used to identify and order it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3071 impeller weigh?\u003c\/strong\u003e The Sierra 18-3071 impeller weighs 0.35 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-3071 impeller?\u003c\/strong\u003e Product dimensions for the 18-3071 impeller are 1.25 x 6 x 7 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the impeller have?\u003c\/strong\u003e The Sierra 18-3071 has a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace my outboard water pump impeller?\u003c\/strong\u003e An impeller like the Sierra 18-3071 should be replaced as part of routine cooling system maintenance or as soon as reduced water flow or overheating is noticed, since worn vanes can no longer move enough cooling water through the engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if I do not replace a worn impeller?\u003c\/strong\u003e A worn impeller loses its ability to pump adequate cooling water, which can cause the outboard engine to overheat; the Sierra 18-3071 is intended to restore proper water pump flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-3071 come with the pump housing or bolts?\u003c\/strong\u003e No, the Sierra 18-3071 is the impeller only; it does not include the pump housing, mounting bolts, or the insert cup used elsewhere in the water pump assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-3071 genuine Sierra or aftermarket?\u003c\/strong\u003e The 18-3071 is a Sierra-branded impeller manufactured to meet or exceed original equipment quality as a replacement for the Yamaha factory part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Sierra 18-3071?\u003c\/strong\u003e The UPC for the Sierra 18-3071 impeller is 030999315236.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988138799323,"sku":"SIE-18-3071","price":22.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3071_lg__14378.1558124969.500.750.jpg?v=1785188677","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3071-water-pump-impeller-for-yamaha-2-stroke-outboards-replaces-yamaha-oem-6e5-44352-01-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
