This gear plays a role in transferring power through the gearcase, and any wear shows up fast once the engine is under stress. I’ve seen gears like this cause vibration or loss of efficiency when they start to go. When it’s in good shape, everything runs smooth and power transfers clean to the prop.\u003c\/p\u003e\n\u003chr data-start=\"520\" data-end=\"523\"\u003e\n\u003ch2 data-section-id=\"14at72t\" data-start=\"525\" data-end=\"542\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"544\" data-end=\"996\"\u003e• \u003cstrong data-start=\"546\" data-end=\"575\"\u003ePower Transfer Function –\u003c\/strong\u003e Moves engine power through the lower unit to support propulsion.\u003cbr data-start=\"640\" data-end=\"643\"\u003e• \u003cstrong data-start=\"645\" data-end=\"673\"\u003eGenuine Yamaha Fitment –\u003c\/strong\u003e Designed to match factory gearcase specifications precisely.\u003cbr data-start=\"734\" data-end=\"737\"\u003e• \u003cstrong data-start=\"739\" data-end=\"767\"\u003eSmooth Gear Engagement –\u003c\/strong\u003e Helps reduce noise and ensures efficient operation.\u003cbr data-start=\"819\" data-end=\"822\"\u003e• \u003cstrong data-start=\"824\" data-end=\"856\"\u003eHigh Strength Construction –\u003c\/strong\u003e Built to handle torque and continuous marine use.\u003cbr data-start=\"906\" data-end=\"909\"\u003e• \u003cstrong data-start=\"911\" data-end=\"942\"\u003ePrecision Machined Design –\u003c\/strong\u003e Ensures proper alignment and long-term reliability.\u003c\/p\u003e\n\u003chr data-start=\"998\" data-end=\"1001\"\u003e\n\u003ch2 data-section-id=\"1b7w7ff\" data-start=\"1003\" data-end=\"1035\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"1037\" data-end=\"1145\"\u003eCompatible with select Yamaha outboards using this gear.
