{"product_id":"merc-1224","title":"Mercury MerCruiser Seawater Pump Impeller Kit - 8M0137219","description":"\u003cp\u003eThe Mercury MerCruiser Quicksilver 8M0137219, also referenced as 47-8M0137219, is a genuine OEM heavy duty sea water pump impeller repair kit for select MerCruiser sterndrive and inboard engine applications using the factory brass seawater pump. This kit is designed for brass pump housings with front housing wear or scoring caused by sand, silt, shell fragments, or marine debris. Instead of replacing the full brass pump assembly, the kit uses a shortened heavy duty impeller with an over-molded inner wear plate to restore the front sealing surface and help recover proper seawater pump pressure for engine cooling.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Mercury MerCruiser Quicksilver OEM seawater pump impeller repair kit.\u003c\/li\u003e\n\u003cli\u003ePart number: \u003cstrong\u003e8M0137219\u003c\/strong\u003e; commonly referenced with Mercury\/Quicksilver prefix \u003cstrong\u003e47-8M0137219\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eHeavy duty 8-blade neoprene impeller design for raw-water cooling service.\u003c\/li\u003e\n\u003cli\u003eShortened impeller design measures approximately \u003cstrong\u003e2-5\/8 in. diameter x 2 in. length\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eEngineered approximately \u003cstrong\u003e0.030 in. shorter than a standard impeller\u003c\/strong\u003e to work with the included front wear plate.\u003c\/li\u003e\n\u003cli\u003eIncludes an over-molded inner front wear plate to compensate for scoring or wear at the front of the brass seawater pump housing.\u003c\/li\u003e\n\u003cli\u003eIntended for factory brass sea water pump applications, not plastic or composite pump bodies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eApplication Compatibility\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eDesigned for select \u003cstrong\u003e2000 and newer MerCruiser V6 and V8 applications\u003c\/strong\u003e using the factory brass seawater pump, including commonly associated 4.3L, 5.0L, 350 MAG, 496, and 502 CID configurations where the parts diagram calls for this kit.\u003c\/p\u003e\n\u003cp\u003eCommon application context includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMerCruiser V6 and V8 engines with factory brass seawater pump\u003c\/li\u003e\n\u003cli\u003eMCM\/MIE 4.3L MPI applications where specified\u003c\/li\u003e\n\u003cli\u003eMCM\/MIE 5.0L MPI applications where specified\u003c\/li\u003e\n\u003cli\u003e350 MAG MPI applications where specified\u003c\/li\u003e\n\u003cli\u003e305, 350, 496, and 502 CID MerCruiser applications where specified\u003c\/li\u003e\n\u003cli\u003eSelect Mercury\/MerCruiser 4.5L and 6.2L applications where specified by serial number and pump configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis kit is \u003cstrong\u003enot intended for standard plastic or composite body seawater pumps\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSerial Number Fitment Notice\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eConfirm fitment using the engine serial number, seawater pump body material, and the Mercury\/MerCruiser parts diagram for the exact engine.

The included over-molded wear plate is intended to restore the front wear surface, but deep housing damage, cracks, distorted covers, damaged shafts, or worn seals may require additional pump service. Lubricate the impeller with an approved installation lubricant, confirm correct impeller vane direction during assembly, and replace related seals or gaskets supplied with the kit. Use the Mercury\/MerCruiser service manual procedure for the specific engine and pump assembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8M0137219\u003c\/strong\u003e — Mercury\/MerCruiser Quicksilver kit number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e47-8M0137219\u003c\/strong\u003e — Mercury\/Quicksilver prefixed impeller kit reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8M0103389\u003c\/strong\u003e — Heavy duty shortened impeller component\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8M0072979\u003c\/strong\u003e — Over-molded inner front wear plate component\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8M2021987\u003c\/strong\u003e — Custom formed rubber O-ring component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis kit is useful when the brass seawater pump housing has light to moderate front wear but the complete pump body does not need replacement. The shorter impeller and wear plate work together as a matched repair setup, so standard-length impellers should not be mixed into this configuration. Always confirm the pump style before ordering because similar MerCruiser engines may use different seawater pump housings depending on year, serial range, and cooling-system layout.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563916853284,"sku":"8M0137219","price":85.16,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/9d40d776-0d11-462a-9127-5ed5aa7f3773.png?v=1780971359","url":"https:\/\/marisolmarine.com\/products\/merc-1224","provider":"Marisol Marine Company","version":"1.0","type":"link"}
