When it’s strong, smooth, and dependable, you feel it instantly—your boat lifts with purpose, tracks clean through chop, and settles into a rhythm that just feels right. That kind of confidence is priceless, especially when you’re miles from the ramp with a full crew and the weather starts shifting. The Mercury 8M0046738 Complete Gearcase is built for boaters who rely on their equipment not just for performance, but for peace of mind. It restores that steady, predictable feel you remember from the boat’s best days.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eComplete OEM gearcase for Bravo Three, Three X, and Three XR sterndrives\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e1.81, 2.00, and 2.20 gear ratio\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e applications\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eC\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eorrosion-fighting XK360 alloy for long-term durability\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eTri-Paint protective coating resists harsh marine environments\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHeavy-duty near-net forged gears for smoother, stronger engagement\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFactory-spec construction for precise fit and optimal performance\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBravo Three and Bravo Three X sterndrives\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e with 1.81, 2.00, or 2.20 gear ratios\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eB\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eravo Three XR sterndrives\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e with 2.00 gear ratio\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon boat types:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eOffshore fishing boats\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSport cruisers\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eTow and surf boats\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMulti-engine offshore setups\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHeavier cabin boats and performance hulls\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWhen you bolt on the 8M0046738 gearcase, the difference is more than mechanical—it’s something you feel every moment you’re behind the helm.
