The Quicksilver 8M6010299 Thermostat is one of those quiet protectors. It keeps your Yamaha 150–200hp 4-stroke running at the temperature it was engineered for, whether you’re drifting over calm flats at sunrise or hammering through afternoon chop to beat the weather home. It’s the kind of part that brings real peace of mind: steady heat control, consistent performance, and the confidence that your outboard’s heart is beating exactly as it should.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eYamaha F\/VF150 through F\/VF200 4-stroke outboards\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eBuilt to \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ematch all OEM specifications\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e for reliability and temperature accuracy\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHigh-quality marine-grade construction for long service life\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThermostat only\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e — installation hardware and seals sold separately\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eReplaces Yamaha \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e6DA-12411-00-00\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e and \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e6DA-12411-01-00\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eFits Yamaha \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e150hp–200hp\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e 4-stroke outboards, including F150, F175, F200, VF150, and VF200\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon on a wide range of boats:Bay boats and flats skiffs\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCenter consoles\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePontoon boats\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMulti-species fishing rigs\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eRunabouts and coastal cruisers\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with both fresh and saltwater environments\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eA good thermostat doesn’t just “open and close.” It quietly shapes the entire feel of your engine.
