A thermostat is one of those pieces—simple, essential, and absolutely tied to how your motor behaves on the water. The Quicksilver 8M6010304 143-degree thermostat gives your Evinrude, Johnson, or OMC two-stroke a steady, predictable operating temperature, the same way it ran when it was new. Whether you’re idling out before dawn or pushing toward your favorite offshore ledge, there’s real comfort in knowing your cooling system is doing its job without hesitation.\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\u003cspan data-preserver-spaces=\"true\"\u003eMaintains a reliable 143° F operating temperature\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSingle-piece, Vernatherm-style thermostat for consistent performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBuilt to match full OEM specifications\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThermostat only (installation hardware sold separately)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDirect replacement for OEM part number 436195\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned specifically for select 60–70 horsepower two-stroke models\u003c\/span\u003e\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 select \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e60–70 horsepower Evinrude, Johnson, and OMC two-stroke outboards\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for mid-size fishing boats, skiffs, pontoons, runabouts, and vintage rigs still running strong\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks with both freshwater and saltwater setups when properly maintained\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal for V4 platforms that rely on stable thermal control for fuel efficiency and longevity\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\"\u003eTwo-stroke e\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003engines have their own heartbeat—any longtime boater can tell when the temperature isn’t quite right.
