When it is built right, you feel the difference every time you ease out of the slip, trim up onto plane or settle into a long cruise along open water. The Quicksilver Alpha One Gen II Sterndrive with a 1.47 gear ratio brings that steady confidence back into your boat—no hesitation, no surprises, just a smooth, sure connection between your engine and the water. Whether you are navigating a tight marina or running down the coastline at first light, it is the kind of drive that lets you relax and focus on the day ahead.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eComplete stan\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003edard-rotation sterndrive replacement for Quicksilver 350 MPI Alpha propulsion systems\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eTri-Paint protective coating creates a tough, multi-layer barrier against corrosion\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eConstructed with XK360 low-copper alloy for enhanced durability in harsh marine environments\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSpiral-cut steel bevel gears engineered for strength and long wear\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eGear design refined for quieter, smoother operation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eMercury Marin\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003ee part number 51100008P\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for Quicksilver 350 MPI Alpha sterndrive engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for many runabouts, sport boats and family cruisers in the Alpha One Gen II lineup\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal for single-engine applications where standard rotation is required\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks well for recreational boating, coastal cruising and watersports\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eA good drive should feel solid and predictable, and that is exactly what this one delivers.

Acceleration stays steady without vibration, and the drive holds firm even as you push into chop or load up the boat with crew and gear. The corrosion-resistant alloys and multi-layer coating help the drive shrug off salt, spray and long days in the water—so you spend more time boating and less time worrying about hidden wear.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eInstallation is straightforward, and once in place, the drive becomes one of those components you do not think much about because everything simply works.
