This kit is designed to restore proper water pump performance and cooling-system function, and Mercury describes it as one of the more complete repair kits for these applications. The published fitment trail centers on \u003cstrong\u003e25HP to 50HP 2-stroke and 4-stroke outboards\u003c\/strong\u003e, with especially strong support across the 25\/30\/40\/45\/50HP range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine \u003cstrong\u003eMercury MerCruiser \/ Quicksilver\u003c\/strong\u003e part number \u003cstrong\u003e821354A2\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eWater pump repair kit for select \u003cstrong\u003e25HP–50HP\u003c\/strong\u003e outboards\u003c\/li\u003e\n\u003cli\u003eIncludes \u003cstrong\u003ewater pump impeller, drive key, face plate, gaskets, and water tube seal\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned to help restore \u003cstrong\u003ecooling flow and water pump function\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eOEM service kit for Mercury and Mariner outboard applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eEngine Compatibility\u003c\/strong\u003e\u003cbr\u003eThe strongest confirmed application trail covers \u003cstrong\u003eMercury and Mariner 25HP, 30HP, 40HP, 45HP, and 50HP\u003c\/strong\u003e outboards in both \u003cstrong\u003e2-stroke and 4-stroke\u003c\/strong\u003e configurations. Mercury's own listing describes it broadly for \u003cstrong\u003e25–50HP 2-stroke and 4-stroke outboards\u003c\/strong\u003e, while additional parts references show extensive serial-range coverage across those engine families. Exact fitment should still be confirmed by engine serial number before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSerial Number Fitment Notice\u003c\/strong\u003e\u003cbr\u003ePlease confirm fitment by \u003cstrong\u003eengine model and serial number\u003c\/strong\u003e before ordering. Mercury specifically directs owners to use the owner's manual or service manual for exact application and replacement instructions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003cbr\u003eReplace this kit when the water pump is due for service, when the impeller has worn or failed, or when cooling performance has dropped and the pump needs a full refresh. Since this is a repair kit rather than a single loose impeller, it is a strong choice when servicing multiple wear components in the water pump assembly at the same time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003cbr\u003eInstall only on the correct Mercury or Mariner application and verify fitment before ordering. Matching by \u003cstrong\u003epart number, engine horsepower, stroke type, and serial number\u003c\/strong\u003e is the safest approach. Mercury also recommends using the service manual for exact replacement instructions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlternate \/ Superseded Part Numbers\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e821354A2\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eRelated replacement references commonly grouped with this kit include \u003cstrong\u003e821354A1\u003c\/strong\u003e and \u003cstrong\u003e821354A04\u003c\/strong\u003e, but those should still be confirmed against the exact application before substituting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003cbr\u003eThe biggest advantage of \u003cstrong\u003e821354A2\u003c\/strong\u003e is that it goes beyond just the impeller.
