Precision-engineered for smooth engagement, this gear plays a key role in forward propulsion and overall drivetrain efficiency. It works in coordination with other internal gears to ensure reliable shifting and consistent performance on the water. If worn or damaged, it can cause grinding, slipping, or reduced performance. Replacing it helps restore smooth operation and dependable power transfer. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr data-start=\"728\" data-end=\"731\"\u003e\n\u003ch2 data-section-id=\"1j5qwet\" data-start=\"733\" data-end=\"752\"\u003e\u003cspan role=\"text\"\u003e\u003cstrong data-start=\"736\" data-end=\"752\"\u003eKey Features\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul data-start=\"754\" data-end=\"1122\"\u003e\n\u003cli data-section-id=\"1rq13q9\" data-start=\"754\" data-end=\"851\"\u003e\n\u003cstrong data-start=\"756\" data-end=\"783\"\u003ePower Transfer Function\u003c\/strong\u003e – Transmits engine power through the lower unit to the propeller.\u003c\/li\u003e\n\u003cli data-section-id=\"13iln4h\" data-start=\"852\" data-end=\"934\"\u003e\n\u003cstrong data-start=\"854\" data-end=\"879\"\u003ePrecision Gear Design\u003c\/strong\u003e – Ensures smooth engagement and efficient operation.\u003c\/li\u003e\n\u003cli data-section-id=\"f9s45w\" data-start=\"935\" data-end=\"1030\"\u003e\n\u003cstrong data-start=\"937\" data-end=\"964\"\u003eOEM Yamaha Construction\u003c\/strong\u003e – Built to factory specifications for durability and exact fit.\u003c\/li\u003e\n\u003cli data-section-id=\"8at9mx\" data-start=\"1031\" data-end=\"1122\"\u003e\n\u003cstrong data-start=\"1033\" data-end=\"1059\"\u003eLower Unit Integration\u003c\/strong\u003e – Designed for proper function within the gearcase assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1232\" data-end=\"1235\"\u003e\n\u003ch2 data-section-id=\"1ww02hn\" data-start=\"1237\" data-end=\"1271\"\u003e\u003cspan role=\"text\"\u003e\u003cstrong data-start=\"1240\" data-end=\"1271\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp data-start=\"1273\" data-end=\"1415\"\u003eCompatible with Yamaha outboards using this component within the \u003cstrong data-start=\"1338\" data-end=\"1372\"\u003elower unit \/ gearcase assembly\u003c\/strong\u003e (commonly found in mid-range outboards).\u003c\/p\u003e\n\u003chr data-start=\"1417\" data-end=\"1420\"\u003e\n\u003ch2 data-section-id=\"elc90z\" data-start=\"1422\" data-end=\"1432\"\u003e\u003cspan role=\"text\"\u003e\u003cstrong data-start=\"1425\" data-end=\"1432\"\u003eFAQ\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp data-start=\"1434\" data-end=\"1545\"\u003e\u003cstrong data-start=\"1434\" data-end=\"1464\"\u003eQ: What does this gear do?\u003c\/strong\u003e\u003cbr data-start=\"1464\" data-end=\"1467\"\u003eA: It transfers rotational power within the lower unit to drive the propeller.\u003c\/p\u003e\n\u003cp data-start=\"1547\" data-end=\"1664\"\u003e\u003cstrong data-start=\"1547\" data-end=\"1598\"\u003eQ: What are signs this gear is worn or damaged?\u003c\/strong\u003e\u003cbr data-start=\"1598\" data-end=\"1601\"\u003eA: Grinding noise, vibration, slipping, or difficulty shifting.\u003c\/p\u003e\n\u003cp data-start=\"1666\" data-end=\"1762\"\u003e\u003cstrong data-start=\"1666\" data-end=\"1708\"\u003eQ: Is this part inside the lower unit?\u003c\/strong\u003e\u003cbr data-start=\"1708\" data-end=\"1711\"\u003eA: Yes, it is an internal gear within the gearcase.\u003c\/p\u003e\n\u003cp data-start=\"1764\" data-end=\"1886\"\u003e\u003cstrong data-start=\"1764\" data-end=\"1801\"\u003eQ: Is this a high-wear component?\u003c\/strong\u003e\u003cbr data-start=\"1801\" data-end=\"1804\"\u003eA: It can wear over time, especially with poor lubrication or water contamination.\u003c\/p\u003e\n\u003cp data-start=\"1888\" data-end=\"2026\"\u003e\u003cstrong data-start=\"1888\" data-end=\"1921\"\u003eQ: Is installation difficult?\u003c\/strong\u003e\u003cbr data-start=\"1921\" data-end=\"1924\"\u003eA: Yes, it requires disassembly of the lower unit and is typically handled by experienced technicians.\u003c\/p\u003e","brand":"Yamaha","offers":[{"title":"Default Title","offer_id":46938245529891,"sku":"689-45560-10-00","price":228.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/PV234779.jpg?v=1698804766","url":"https:\/\/partsvu.com\/en-mx\/products\/yamaha-gear-689-45560-10-00","provider":"PartsVu","version":"1.0","type":"link"}
