Gear 1 handles a big part of the power transfer, and when it starts to wear, you’ll hear it and feel it right away. I’ve seen these cause everything from rough shifting to full-on slipping under throttle. Getting a fresh, properly machined gear back in place brings everything back to that solid, tight Yamaha feel.\u003c\/p\u003e\n\u003chr data-start=\"542\" data-end=\"545\"\u003e\n\u003ch2 data-section-id=\"14at72t\" data-start=\"547\" data-end=\"564\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"566\" data-end=\"665\"\u003e• \u003cstrong data-start=\"568\" data-end=\"594\"\u003e21-Tooth Gear Design –\u003c\/strong\u003e Maintains proper gear ratio for smooth and efficient power transfer.\u003c\/p\u003e\n\u003cp data-start=\"667\" data-end=\"759\"\u003e• \u003cstrong data-start=\"669\" data-end=\"694\"\u003ePrecision Cut Teeth –\u003c\/strong\u003e Ensures clean engagement and reduces internal drivetrain wear.\u003c\/p\u003e\n\u003cp data-start=\"761\" data-end=\"860\"\u003e• \u003cstrong data-start=\"763\" data-end=\"785\"\u003eOEM Fit Accuracy –\u003c\/strong\u003e Matches Yamaha factory specifications for proper alignment and function.\u003c\/p\u003e\n\u003cp data-start=\"862\" data-end=\"957\"\u003e• \u003cstrong data-start=\"864\" data-end=\"896\"\u003eHigh Strength Construction –\u003c\/strong\u003e Built to handle torque, load, and harsh marine conditions.\u003c\/p\u003e\n\u003chr data-start=\"959\" data-end=\"962\"\u003e\n\u003ch2 data-section-id=\"1b7w7ff\" data-start=\"964\" data-end=\"996\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"998\" data-end=\"1098\"\u003eVerify compatibility with your specific Yamaha outboard model and part number before installation.\u003c\/p\u003e\n\u003chr data-start=\"1100\" data-end=\"1103\"\u003e\n\u003ch2 data-section-id=\"w36ijk\" data-start=\"1105\" data-end=\"1114\"\u003eFAQs\u003c\/h2\u003e\n\u003cp data-start=\"1116\" data-end=\"1231\"\u003e\u003cstrong data-start=\"1116\" data-end=\"1161\"\u003eQ1: What are signs this gear is worn out?\u003c\/strong\u003e\u003cbr data-start=\"1161\" data-end=\"1164\"\u003eA: Grinding noise, slipping under load, or rough gear engagement.\u003c\/p\u003e\n\u003cp data-start=\"1233\" data-end=\"1391\"\u003e\u003cstrong data-start=\"1233\" data-end=\"1294\"\u003eQ2: Can I replace just this gear instead of the full set?\u003c\/strong\u003e\u003cbr data-start=\"1294\" data-end=\"1297\"\u003eA: You can, but if other gears show wear, replacing the full set is usually the better move.\u003c\/p\u003e\n\u003cp data-start=\"1393\" data-end=\"1512\"\u003e\u003cstrong data-start=\"1393\" data-end=\"1431\"\u003eQ3: What causes this gear to fail?\u003c\/strong\u003e\u003cbr data-start=\"1431\" data-end=\"1434\"\u003eA: Poor gear oil condition, heavy load use, or debris inside the lower unit.\u003c\/p\u003e\n\u003cp data-start=\"1514\" data-end=\"1625\"\u003e\u003cstrong data-start=\"1514\" data-end=\"1560\"\u003eQ4: Will this affect shifting performance?\u003c\/strong\u003e\u003cbr data-start=\"1560\" data-end=\"1563\"\u003eA: Yes, worn gears can cause rough or inconsistent shifting.\u003c\/p\u003e\n\u003cp data-start=\"1627\" data-end=\"1744\"\u003e\u003cstrong data-start=\"1627\" data-end=\"1668\"\u003eQ5: Is this a difficult installation?\u003c\/strong\u003e\u003cbr data-start=\"1668\" data-end=\"1671\"\u003eA: It requires full lower unit disassembly, so experience is important.\u003c\/p\u003e","brand":"Yamaha","offers":[{"title":"Default Title","offer_id":46937642959139,"sku":"6CB-45561-00-00","price":456.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/PV243159.jpg?v=1698802501","url":"https:\/\/partsvu.com\/en-au\/products\/yamaha-gear-1-21t-6cb-45561-00-00","provider":"PartsVu","version":"1.0","type":"link"}
