Manufactured to OEM specifications using durable neoprene rubber, it restores reliable raw-water cooling performance across applicable Mercury\/Mariner outboard engine configurations. At 77g, this impeller is suited to a range of Mercury and Mariner outboard applications. Sierra impellers are a trusted choice for marine technicians and boat owners performing routine cooling system maintenance.\u003c\/p\u003e\u003ch3\u003eBest Use — Parts Desk Insight\u003c\/h3\u003e\u003cp\u003eDesigned for Mercury and Mariner outboard applications — always confirm fitment against Sierra's current application guide by engine horsepower, model, and year before ordering. Mercury outboards are sensitive to impeller condition; a worn or heat-set impeller can cause overheating and powerhead damage quickly. Replace on a seasonal schedule or every 100–200 hours of operation, whichever comes first. During service: remove the lower unit, inspect the pump housing, wear plate, and cam for scoring or grooves — replace the housing if damaged, as a scored housing will destroy a new impeller rapidly. Lubricate the impeller with dish soap or glycerin only — never petroleum-based products. Never run the engine out of water, even briefly. After installation, verify water flow from the tell-tale before returning the boat to service.\u003c\/p\u003e\u003ch3\u003eCompatible \u0026amp; Related Products\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sierra-3059-johnson-evinrude-impeller\"\u003eSierra 3059 Johnson\/Evinrude Impeller\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sierra-31041-johnson-evinrude-impeller\"\u003eSierra 31041 Johnson\/Evinrude Impeller\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sierra-3058-johnson-evinrude-impeller\"\u003eSierra 3058 Johnson\/Evinrude Impeller\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sierra-3245-honda-impeller\"\u003eSierra 3245 Honda Impeller\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sierra-8900-impeller\"\u003eSierra 8900 Impeller\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sierra-3275-volvo-impeller-kit\"\u003eSierra 3275 Volvo Impeller Kit\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sierra-32761-volvo-impeller-kit\"\u003eSierra 32761 Volvo Impeller Kit\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eSee Sierra's current catalog for complete application information and fitment verification.\u003c\/em\u003e\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51156142915620,"sku":"47-3056","price":54.69,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/a0c44d55-61f7-4105-a42b-55fc2092c9b4.png?v=1785115382","url":"https:\/\/marisolmarine.com\/products\/sierra-3056-impeller","provider":"Marisol Marine Company","version":"1.0","type":"link"}
