This assembly is built for LF300 and LF350 platforms, delivering smooth, consistent power transfer from the engine down to the prop. Whether you're running long offshore trips or pushing through rough water, having a solid gearcase underneath matters. If your current unit is worn or starting to show signs of failure, replacing it brings back that confident, steady performance you expect from a Yamaha.\u003c\/p\u003e\n\u003chr data-start=\"718\" data-end=\"721\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"723\" data-end=\"738\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"740\" data-end=\"1110\"\u003e• Heavy-Duty Gearcase Assembly – Designed to handle high horsepower loads and offshore use.\u003cbr data-start=\"831\" data-end=\"834\"\u003e• Efficient Power Transfer – Ensures smooth delivery of engine power to the propeller.\u003cbr data-start=\"920\" data-end=\"923\"\u003e• Corrosion-Resistant Build – Built to withstand harsh saltwater and marine conditions.\u003cbr data-start=\"1010\" data-end=\"1013\"\u003e• OEM Yamaha Fitment – Engineered to factory specs for proper alignment and reliable operation.\u003c\/p\u003e\n\u003chr data-start=\"1112\" data-end=\"1115\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"1117\" data-end=\"1147\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"1149\" data-end=\"1209\"\u003e• LF300 - 2007-2009\u003cbr data-start=\"1168\" data-end=\"1171\"\u003e• LF350 - 2007-2012\u003cbr data-start=\"1190\" data-end=\"1193\"\u003e• FL350 - 2010\u003c\/p\u003e\n\u003chr data-start=\"1211\" data-end=\"1214\"\u003e\n\u003ch2 data-section-id=\"1hryhf7\" data-start=\"1216\" data-end=\"1222\"\u003eFAQ\u003c\/h2\u003e\n\u003cp data-start=\"1224\" data-end=\"1374\"\u003e\u003cstrong data-start=\"1224\" data-end=\"1277\"\u003eQ: What are signs a lower unit needs replacement?\u003c\/strong\u003e\u003cbr data-start=\"1277\" data-end=\"1280\"\u003eA: Grinding noise, vibration, shifting issues, or water in the gear oil are common indicators.\u003c\/p\u003e\n\u003cp data-start=\"1376\" data-end=\"1495\"\u003e\u003cstrong data-start=\"1376\" data-end=\"1422\"\u003eQ: Is this a complete lower unit assembly?\u003c\/strong\u003e\u003cbr data-start=\"1422\" data-end=\"1425\"\u003eA: Yes, it’s a full gearcase assembly designed for direct replacement.\u003c\/p\u003e\n\u003cp data-start=\"1497\" data-end=\"1660\"\u003e\u003cstrong data-start=\"1497\" data-end=\"1554\"\u003eQ: Will replacing the lower unit improve performance?\u003c\/strong\u003e\u003cbr data-start=\"1554\" data-end=\"1557\"\u003eA: If your current unit is worn or damaged, it will restore smooth operation and proper power transfer.\u003c\/p\u003e\n\u003cp data-start=\"1662\" data-end=\"1778\"\u003e\u003cstrong data-start=\"1662\" data-end=\"1695\"\u003eQ: Is installation difficult?\u003c\/strong\u003e\u003cbr data-start=\"1695\" data-end=\"1698\"\u003eA: It’s a more advanced repair and typically handled by experienced technicians.\u003c\/p\u003e\n\u003cp data-start=\"1780\" data-end=\"1915\"\u003e\u003cstrong data-start=\"1780\" data-end=\"1818\"\u003eQ: Are these updated part numbers?\u003c\/strong\u003e\u003cbr data-start=\"1818\" data-end=\"1821\"\u003eA: Yes, these assemblies supersede earlier versions while maintaining proper fit and function.\u003c\/p\u003e","brand":"Yamaha","offers":[{"title":"Default Title","offer_id":46937842581795,"sku":"6AX-45300-3A-8D","price":8235.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/6ax-45300-3a-8d.jpg?v=1698803370","url":"https:\/\/partsvu.com\/en-mx\/products\/yamaha-lower-unit-assembly-lf300-lf350-fl350-6ax-45300-3a-8d-see-description-for-applicable-model","provider":"PartsVu","version":"1.0","type":"link"}
