This Gear 1 Assembly plays a key role in transferring power smoothly from the driveshaft to the prop, especially when you’re shifting under load or cruising for long stretches. It’s the kind of part you don’t think about until shifting gets rough or you start hearing something you shouldn’t. Built for durability and proper engagement, it keeps your drivetrain running the way Yamaha intended out on the water.\u003c\/p\u003e\n\u003chr data-start=\"632\" data-end=\"635\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"639\" data-end=\"654\"\u003eKey Features\u003c\/h2\u003e\n\u003cul data-start=\"656\" data-end=\"1092\"\u003e\n\u003cli data-section-id=\"1blt8qw\" data-start=\"656\" data-end=\"773\"\u003e\n\u003cstrong data-start=\"658\" data-end=\"687\"\u003ePrecision Gear Engagement\u003c\/strong\u003e – Designed to mesh cleanly with mating components for smooth and reliable shifting.\u003c\/li\u003e\n\u003cli data-section-id=\"1b73lkl\" data-start=\"775\" data-end=\"882\"\u003e\n\u003cstrong data-start=\"777\" data-end=\"808\"\u003eHardened Steel Construction\u003c\/strong\u003e – Built to handle continuous load, torque, and harsh marine conditions.\u003c\/li\u003e\n\u003cli data-section-id=\"1jm3ijr\" data-start=\"884\" data-end=\"985\"\u003e\n\u003cstrong data-start=\"886\" data-end=\"913\"\u003eOptimized Tooth Profile\u003c\/strong\u003e – Reduces wear and noise during operation, especially under throttle.\u003c\/li\u003e\n\u003cli data-section-id=\"1xynow8\" data-start=\"987\" data-end=\"1092\"\u003e\n\u003cstrong data-start=\"989\" data-end=\"1015\"\u003eDirect Replacement Fit\u003c\/strong\u003e – Matches original Yamaha specifications for straightforward installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1096\" data-end=\"1099\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"1103\" data-end=\"1133\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"1135\" data-end=\"1409\"\u003eCompatible with a wide range of Yamaha outboard engines that utilize this style of lower unit gear assembly.
