You feel it when you push off from the dock — that quiet confidence in knowing your outboard is running at the temperature it was built for. The Quicksilver 8M6010302 Thermostat brings that kind of peace of mind. It’s small, sure, but it plays a huge role in keeping your motor steady, responsive, and ready for long days exploring hidden coves or riding back in through a choppy inlet. When the temperature is right, everything just works smoother, and you can focus on the water instead of what’s happening under the cowling.\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 proper operating temperature for select 6–55hp Evinrude, Johnson, and OMC two-stroke outboards\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned to meet OEM specifications for 143°F operation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDurable thermostat engineered for consistent, reliable heat regulation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThermostat only — seals, gaskets, and mounting hardware sold separately\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBuilt to match exact fit and performance requirements of the original part\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits select Evinrude, Johnson, and OMC two-stroke outboards from 6–55hp\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with V4 and V6 Crossflow outboard engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommonly used on runabouts, skiffs, tiller-steered fishing boats, and lightweight utility hulls\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks with standard two-stroke cooling systems found on these models\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\"\u003eWhen a thermos\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003etat performs exactly as it should, you don’t have to think about it — and that’s the beauty of this part. At 143°F, the engine warms quickly but avoids the stress caused by running too hot. You’ll notice smoother idle, cleaner throttle response, and a steadier feel when cruising. It helps maintain proper fuel burn, protects internal components, and keeps your outboard from laboring unnecessarily.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eOn older two-stroke motors especially, temperature swings can lead to everything from fouled plugs to excessive wear. This Quicksilver thermostat delivers tight, predictable control so your engine stays in the zone where it’s happiest.

OEM-grade components like this Quicksilver unit are built to match the precise heat range, opening rate, and durability your engine was engineered around. Aftermarket versions often drift out of spec, stick open, or fail early, leaving your motor running too cold or too hot. With Quicksilver, you get reliability you can trust season after season.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIf a friend on the dock asked for advice, you’d probably say the same thing: \u003c\/span\u003e\u003cem\u003e\u003cspan data-preserver-spaces=\"true\"\u003euse the part that’s built to the original standard\u003c\/span\u003e\u003c\/em\u003e\u003cspan data-preserver-spaces=\"true\"\u003e.
