The ones buried deep inside the sterndrive that keep everything feeling tight, smooth, and predictable. The Mercury Marine part number 861792 Driven Gear Bearing is one of those pieces you trust without needing to think about it. You install it, you head back out, and you just know the drive beneath you is ready for whatever the day turns into.\u003c\/p\u003e\n\u003chr data-start=\"645\" data-end=\"648\"\u003e\n\u003cp data-start=\"650\" data-end=\"668\"\u003e\u003cstrong data-start=\"650\" data-end=\"666\"\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"669\" data-end=\"994\"\u003e\n\u003cli data-start=\"669\" data-end=\"733\"\u003e\n\u003cp data-start=\"671\" data-end=\"733\"\u003eComplete driven gear bearing assembly ready for installation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"734\" data-end=\"799\"\u003e\n\u003cp data-start=\"736\" data-end=\"799\"\u003ePrecision-ground bearing surfaces for smooth, steady rotation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"800\" data-end=\"863\"\u003e\n\u003cp data-start=\"802\" data-end=\"863\"\u003eHardened marine-grade steel for durability under heavy load\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"864\" data-end=\"916\"\u003e\n\u003cp data-start=\"866\" data-end=\"916\"\u003eBuilt to exact Mercury Marine OEM specifications\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"917\" data-end=\"994\"\u003e\n\u003cp data-start=\"919\" data-end=\"994\"\u003eDesigned for consistent alignment and driveline stability in Bravo drives\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"996\" data-end=\"999\"\u003e\n\u003cp data-start=\"1001\" data-end=\"1034\"\u003e\u003cstrong data-start=\"1001\" data-end=\"1032\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1035\" data-end=\"1324\"\u003e\n\u003cli data-start=\"1035\" data-end=\"1128\"\u003e\n\u003cp data-start=\"1037\" data-end=\"1128\"\u003eFits MerCruiser Bravo I, Bravo II, Bravo III, Bravo X, Bravo XR, and Bravo XZ sterndrives\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1129\" data-end=\"1241\"\u003e\n\u003cp data-start=\"1131\" data-end=\"1241\"\u003eSuitable for performance sterndrive boats, offshore hulls, sport boats, cruisers, and high-load applications\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1242\" data-end=\"1324\"\u003e\n\u003cp data-start=\"1244\" data-end=\"1324\"\u003eIdeal for any Bravo-series sterndrive requiring OEM-grade gear bearing support\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1326\" data-end=\"1329\"\u003e\n\u003cp data-start=\"1331\" data-end=\"1744\"\u003e\u003cstrong data-start=\"1331\" data-end=\"1367\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003cbr data-start=\"1367\" data-end=\"1370\"\u003eA driven gear bearing may not be flashy, but out on real water, it plays a starring role in how your boat feels. This 861792 bearing cradles the driven gear with a smooth, secure fit that holds everything true. The rotation feels tight without binding, steady without chatter. You’ll feel the benefit each time you push out of the marina or ease into a long, relaxed cruise.\u003c\/p\u003e\n\u003cp data-start=\"1746\" data-end=\"2058\"\u003eThe hardened steel resists the punishment that naturally comes with Bravo-series power—shock loads, vibration, long runs, tight turns, and the occasional unexpected jolt from the water beneath you. By maintaining alignment and reducing friction, it helps the entire gear assembly last longer and operate quieter.\u003c\/p\u003e\n\u003cp data-start=\"2060\" data-end=\"2333\"\u003eInstallation is straightforward for technicians familiar with Bravo drives. Fitment is exact, so there’s no hunting for shims or compensating for cheap machining. It seats properly, protects your gears, and gives your drive the steady backbone it needs to perform its best.\u003c\/p\u003e\n\u003chr data-start=\"2335\" data-end=\"2338\"\u003e\n\u003cp data-start=\"2340\" data-end=\"2699\"\u003e\u003cstrong data-start=\"2340\" data-end=\"2355\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003cbr data-start=\"2355\" data-end=\"2358\"\u003eWhen it comes to sterndrive internals, there’s simply no room for approximation. Aftermarket bearings can look fine at first glance, but slight inconsistencies in hardness, machining, or surface finish can cause noise, premature wear, or failure. The 861792 is built to the same standard your drive was built with—nothing more, nothing less.\u003c\/p\u003e\n\u003cp data-start=\"2701\" data-end=\"2724\"\u003eChoosing OEM ensures:\u003c\/p\u003e\n\u003cul data-start=\"2725\" data-end=\"2964\"\u003e\n\u003cli data-start=\"2725\" data-end=\"2773\"\u003e\n\u003cp data-start=\"2727\" data-end=\"2773\"\u003eProper tolerances and seamless compatibility\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2774\" data-end=\"2831\"\u003e\n\u003cp data-start=\"2776\" data-end=\"2831\"\u003eLong-term reliability and fewer unexpected breakdowns\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2832\" data-end=\"2885\"\u003e\n\u003cp data-start=\"2834\" data-end=\"2885\"\u003eMaterials and machining trusted by Mercury Marine\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2886\" data-end=\"2964\"\u003e\n\u003cp data-start=\"2888\" data-end=\"2964\"\u003eA smart, cost-effective choice over time, especially for high-load boating\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"2966\" data-end=\"3086\"\u003eIt’s the kind of decision seasoned boaters make because they’ve already lived through what happens when you cut corners.\u003c\/p\u003e\n\u003chr data-start=\"3088\" data-end=\"3091\"\u003e\n\u003cp data-start=\"3093\" data-end=\"3100\"\u003e\u003cstrong data-start=\"3093\" data-end=\"3100\"\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"3102\" data-end=\"3249\"\u003e\u003cstrong data-start=\"3102\" data-end=\"3183\"\u003eQ1: Which Mercury engines or systems does the Driven Gear Bearing 861792 fit?\u003c\/strong\u003e\u003cbr data-start=\"3183\" data-end=\"3186\"\u003eIt fits MerCruiser Bravo I, II, III, X, XR, and XZ sterndrives.\u003c\/p\u003e\n\u003cp data-start=\"3251\" data-end=\"3402\"\u003e\u003cstrong data-start=\"3251\" data-end=\"3311\"\u003eQ2: What sets this part apart from aftermarket bearings?\u003c\/strong\u003e\u003cbr data-start=\"3311\" data-end=\"3314\"\u003eOEM bearings offer superior machining accuracy, correct hardness, and proven durability.\u003c\/p\u003e\n\u003cp data-start=\"3404\" data-end=\"3564\"\u003e\u003cstrong data-start=\"3404\" data-end=\"3468\"\u003eQ3: How do I confirm this is the right bearing for my drive?\u003c\/strong\u003e\u003cbr data-start=\"3468\" data-end=\"3471\"\u003eMatch your sterndrive model and serial number with the specifications in your service manual.\u003c\/p\u003e\n\u003cp data-start=\"3566\" data-end=\"3719\"\u003e\u003cstrong data-start=\"3566\" data-end=\"3638\"\u003eQ4: Is this part suitable for both saltwater and freshwater boating?\u003c\/strong\u003e\u003cbr data-start=\"3638\" data-end=\"3641\"\u003eYes—its hardened steel build performs well in all typical marine environments.\u003c\/p\u003e\n\u003cp data-start=\"3721\" data-end=\"3904\"\u003e\u003cstrong data-start=\"3721\" data-end=\"3773\"\u003eQ5: Is installation simple for most boat owners?\u003c\/strong\u003e\u003cbr data-start=\"3773\" data-end=\"3776\"\u003eBearing installation is best handled by a qualified marine technician, but the part itself is designed for clean, exact fitment.\u003c\/p\u003e","brand":"Mercury","offers":[{"title":"Default Title","offer_id":46940734947619,"sku":"31-861792","price":39.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/861792_main.jpg?v=1760631271","url":"https:\/\/partsvu.com\/en-ca\/products\/mercury-mercruiser-driven-gear-bearing-fits-bravo-i-ii-iii-x-xr-xz-31-861792","provider":"PartsVu","version":"1.0","type":"link"}
