I’ve seen plenty come in with noisy gears or rough shifting that just isn’t worth trying to patch. Dropping in a complete assembly like this gets everything back to smooth, solid operation. It’s the kind of replacement that lets you trust the motor again every time you put it in gear.\u003c\/p\u003e\n\u003chr data-start=\"526\" data-end=\"529\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"531\" data-end=\"546\"\u003eKey Features\u003c\/h2\u003e\n\u003cul data-start=\"547\" data-end=\"929\"\u003e\n\u003cli data-section-id=\"19yrus5\" data-start=\"547\" data-end=\"654\"\u003e\n\u003cstrong data-start=\"549\" data-end=\"579\"\u003eComplete Gearcase Assembly\u003c\/strong\u003e – Includes internal gears and housing for a full lower unit replacement.\u003c\/li\u003e\n\u003cli data-section-id=\"13q8tex\" data-start=\"655\" data-end=\"738\"\u003e\n\u003cstrong data-start=\"657\" data-end=\"682\"\u003eSmooth Power Transfer\u003c\/strong\u003e – Delivers consistent engine output to the propeller.\u003c\/li\u003e\n\u003cli data-section-id=\"1xic15j\" data-start=\"739\" data-end=\"836\"\u003e\n\u003cstrong data-start=\"741\" data-end=\"768\"\u003eHeavy-Duty Construction\u003c\/strong\u003e – Built to handle high horsepower loads and long-term marine use.\u003c\/li\u003e\n\u003cli data-section-id=\"12sgrnp\" data-start=\"837\" data-end=\"929\"\u003e\n\u003cstrong data-start=\"839\" data-end=\"867\"\u003eReliable Gear Engagement\u003c\/strong\u003e – Provides clean shifting with reduced noise and vibration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"931\" data-end=\"934\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"936\" data-end=\"966\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"967\" data-end=\"1128\"\u003eFits Yamaha outboard engines in the 200 to 225 horsepower range.
