You can feel when it’s running right—and you can definitely feel when it’s not. A reliable thermostat is one of those small pieces that quietly holds the whole system together. The Quicksilver 8M6010303 130-degree thermostat brings that steady reassurance back to your Evinrude, Johnson, or OMC two-stroke. Whether you’re easing away from the dock before sunrise or pushing through a choppy afternoon, it keeps your engine running at the temperature it was designed for so you can focus on the water instead of the worries.\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 stable 130° F engine temperature for proper two-stroke performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned to meet all original equipment specifications\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eP\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003erecision-built thermostat only (installation hardware sold separately)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDurable, marine-ready construction for consistent heating and cooling cycles\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDirect replacement for OEM part number 437090\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with V4 and V6 two-stroke platforms\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\u003cspan data-preserver-spaces=\"true\"\u003eFits select 90–250 horsepower Evinrude, Johnson, and OMC two-stroke outboards\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks with both V4 and V6 Crossflow engine families\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eI\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003edeal for fishing boats, older bass boats, offshore skiffs, inflatables, and runabouts powered by legacy two-stroke models\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for freshwater and saltwater applications when paired with proper maintenance\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 thermostat isn’t flashy, but you’ll feel the difference when it’s doing its job.

A thermostat that opens too early or too late can create a chain of small issues that eventually turn into big ones. Quicksilver components are engineered to match original specifications exactly, giving you the right fit, the right temperature behavior, and long-term dependability. Compared to aftermarket units—which often miss the mark on tolerances—this thermostat offers a true set-it-and-forget-it experience. It’s the kind of practical choice seasoned boaters make because they’ve seen what happens when shortcuts don’t pan out.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFAQ\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ1: Which engines does this thermostat fit?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e It fits select 90–250 horsepower Evinrude, Johnson, and OMC V4 and V6 two-stroke outboards.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ2: What sets this thermostat apart from aftermarket replacements?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e The temperature rating, machining quality, and material reliability match OEM specs, ensuring correct operation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ3: How do I confirm it’s right for my engine?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Check your model against your service manual or match the OEM number 437090.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ4: Can it be used in freshwater and saltwater?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Yes—just follow standard maintenance practices.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ5: Is installation easy?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Most boaters with basic tools can replace it, but hardware and gaskets are sold separately.\u003c\/span\u003e\u003c\/p\u003e","brand":"Mercury","offers":[{"title":"Default Title","offer_id":46935057465635,"sku":"8M6010303","price":22.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/8M6010303_Main.jpg?v=1760631551","url":"https:\/\/partsvu.com\/en-mx\/products\/mercury-wa-thermostat-j-e-437090-8m6010303","provider":"PartsVu","version":"1.0","type":"link"}
