As the wear component inside the water pump housing, the impeller drives raw water through the cooling system to keep the engine running at safe operating temperatures; a worn, cracked, or missing vane is one of the most common causes of overheating and reduced cooling flow. The 18-3051 is constructed from aluminum for durability under continuous rotation and contact with the pump housing, and it is rated for use in salt water as well as fresh water service, making it suitable for coastal and offshore applications where corrosion resistance and consistent water flow matter. It operates automatically as part of the engine's cooling circuit, requiring no separate controls once installed. This impeller is sold as a single unit and is intended to be installed as part of a routine water pump service, alongside inspection of the pump housing, wear plate, and gaskets. Sierra manufactures this part to be a straightforward OEM equivalent, so buyers replacing a worn factory impeller can order by the OEM number 395289 or the Sierra part number 18-3051 and get the correct replacement without needing to identify additional cross-reference numbers.\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 18-3051\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 395289\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Engine Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e For Salt Water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999315076\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Impeller\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits engines using OEM impeller 395289; verify against your engine's original part number before ordering.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e395289\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3051 impeller replace?\u003c\/strong\u003e The Sierra 18-3051 is a direct replacement for OEM part number 395289.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-3051 impeller made of rubber or aluminum?\u003c\/strong\u003e The impeller body and mounting hub are constructed from aluminum, though impellers of this type typically pair a metal hub with flexible drive vanes for pumping water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Sierra 18-3051 be used in salt water?\u003c\/strong\u003e Yes, this impeller is rated for salt water use as well as fresh water applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-3051 impeller?\u003c\/strong\u003e It is black in color.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-3051 weigh?\u003c\/strong\u003e The 18-3051 impeller weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3051 come with the water pump housing or gaskets?\u003c\/strong\u003e No, the package includes the impeller only; it does not include the pump housing, wear plate, or gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my impeller needs replacing?\u003c\/strong\u003e Reduced or no water flow from the engine's telltale, overheating, or visibly cracked or missing vanes on the old impeller are signs it is time to install a replacement like the Sierra 18-3051.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3051 an OEM part or an aftermarket part?\u003c\/strong\u003e It is a Sierra aftermarket impeller manufactured as an equivalent to OEM part 395289, not an OEM-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engine type is the 18-3051 impeller designed for?\u003c\/strong\u003e It is listed for 4 stroke engines with a gasoline fuel type and an engine-mounted water pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the operation of the 18-3051 impeller require any manual controls?\u003c\/strong\u003e No, the 18-3051 operates automatically as part of the engine's cooling water pump once installed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many impellers come in one order of part 18-3051?\u003c\/strong\u003e One order includes a single 18-3051 impeller unit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988137324763,"sku":"SIE-18-3051","price":17.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3051_lg__66373.1558123575.500.750.jpg?v=1785188298","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3051-water-pump-impeller-for-johnson-evinrude-outboards-replaces-omc-395289","provider":"Good Vibes Marina","version":"1.0","type":"link"}
