The Quicksilver 8951A33 Counter Rotation (LH) Gearcase brings that feeling back to MerCruiser MR and Alpha One sterndrives. Whether you’re running twin engines offshore or maneuvering a cruiser into a crowded marina, it’s good to know the drive under you is built to handle the hard work without complaint.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eComplete counter-rotation (left-hand) gearcase for MerCruiser MR and Alpha One sterndrives\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eConstructed with XK360 low-copper alloy for enhanced corrosion resistance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFinished with Mercury’s Tri-Paint system for durable, long-lasting protection\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBuilt with spiral-cut Stainless Steel bevel gears for smooth, quiet operation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned and tested to meet Mercury Marine OEM performance standards\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits MerCruiser MR and Alpha One sterndrive models requiring a counter-rotation (LH) gearcase\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal for twin-engine boats using one left-hand and one right-hand drive\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon on bowriders, sport boats, cabin cruisers, offshore fishing boats, and multi-engine setups\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDirect OEM replacement for original LH MerCruiser gearcases\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e A good gearcase changes the way the whole boat feels. With this Quicksilver LH unit under you, shifts feel crisp and positive, even when you’re working through tight spots around a marina or adjusting the boat’s angle in wind or current. The spiral-cut bevel gears run smooth and quiet, reducing chatter and vibration at all speeds. That means less fatigue at the helm and a more relaxed day on the water especially during long runs.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThe corrosion-resistant XK360 alloy and Tri-Paint finish hold up beautifully in tough environments. Whether you’re in salt, brackish water, or freshwater lakes that see big temperature swings, the housing is built to resist pitting and wear. It’s designed to take the kind of punishment that comes from years of launching, trailering, docking, and idling in shallow water. Once installed, the gearcase delivers the kind of steady, predictable performance that lets you focus on where you’re headed, not what’s happening below the transom.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWhy Buy OEM\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Gearcases are not the kind of component you gamble with. Mercury Marine parts are engineered to match the power curve, shift characteristics, and load expectations of MerCruiser sterndrives. Aftermarket cases may bolt up, but internal tolerances, gear hardness, and hydrodynamic shaping often vary just enough to cause long-term problems. \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eAn OEM Quicksilver gearcase \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003egives\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e you fitment you can trust, long-term reliability, and the \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003ecomfort\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e of knowing your boat will respond exactly \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003ehow\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e MerCruiser designed it to.\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e It’s the kind of choice seasoned boaters make because they’ve learned the value of getting it right the first time.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFAQ\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ1: Which MerCruiser systems does this gearcase fit?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e It fits MerCruiser MR and Alpha One sterndrives requiring a counter-rotation (left-hand) gearcase.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ2: What makes this different from aftermarket gearcases?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e OEM housings use corrosion-resistant XK360 alloy, spiral-cut gears, and Mercury’s Tri-Paint finish for lasting performance.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ3: How do I know if this is the correct replacement?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e If your sterndrive requires an LH counter-rotation case and your model is MR or Alpha One, part number 8951A33 is the correct match.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ4: Can it be used in both saltwater and freshwater?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Yes it’s engineered for harsh marine exposure with corrosion-resistant alloys and coatings.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ5: Is installation straightforward?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Most marine technicians can install it quickly, and many experienced boat owners can handle it with proper tools.\u003c\/span\u003e\u003c\/p\u003e","brand":"Mercury","offers":[{"title":"Default Title","offer_id":46941261693219,"sku":"1623-8951A26","price":2960.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/PV502154_6.jpg?v=1698817188","url":"https:\/\/partsvu.com\/en-mx\/products\/mercury-gc-alpha-c-r-1623-8951a26","provider":"PartsVu","version":"1.0","type":"link"}
