Proper thermostat function is critical on a marine outboard: it regulates coolant flow through the powerhead so the engine reaches and holds its intended operating temperature, protecting against overheating on one end and inefficient, incomplete combustion from running too cool on the other. A worn, stuck, or corroded thermostat is a common cause of erratic temperature gauge readings, overheating alarms, or reduced performance, and replacing it is standard maintenance for these outboard models.\u003c\/p\u003e\u003cp\u003eThis thermostat is sold under Sierra part number 18-3545 and is built to replace the original equipment thermostat rated for the same 130 degree opening temperature, so it drops in without requiring a change in cooling system calibration. It is designed to fit Evinrude E200, E225, and E250 outboards (2000-05) and Johnson J200, J225, and J250 outboards (2000-01).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-3545\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Thermostat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Temperature:\u003c\/strong\u003e 130 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 3.2 cm (L) x 9.6 cm (W) x 11.8 cm (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 5001036\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Evinrude E200, E225, E250 (2000-05); Johnson J200, J225, J250 (2000-01)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEvinrude E200, E225, E250 (2000-05)\u003c\/li\u003e\n\u003cli\u003eJohnson J200, J225, J250 (2000-01)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e5001036\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-3545 thermostat fit?\u003c\/strong\u003e The 18-3545 thermostat fits Evinrude E200, E225, and E250 outboards (2000-05), as well as Johnson J200, J225, and J250 outboards (2000-01).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat temperature does this thermostat open at?\u003c\/strong\u003e It is rated to open at 130 degrees Fahrenheit, matching the original thermostat specification for these Evinrude and Johnson outboard models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3545 an OEM-equivalent part?\u003c\/strong\u003e Yes, Sierra part number 18-3545 replaces OEM number 5001036 and is built to the same 130 degree opening specification for a direct fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-3545 thermostat?\u003c\/strong\u003e This thermostat is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3545 thermostat weigh?\u003c\/strong\u003e It weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of this thermostat?\u003c\/strong\u003e The 18-3545 thermostat ships in packaging measuring 3.2 cm (L) x 9.6 cm (W) x 11.8 cm (H).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this thermostat work on a Johnson outboard as well as an Evinrude?\u003c\/strong\u003e Yes, part number 18-3545 is designed to fit both Johnson (J200, J225, J250, 2000-01) and Evinrude (E200, E225, E250, 2000-05) outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-3545 cross-reference to?\u003c\/strong\u003e It replaces OEM part number 5001036.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my thermostat needs to be replaced?\u003c\/strong\u003e Symptoms like an overheating alarm, an erratic temperature gauge, or an engine that runs too cool typically point to a failed thermostat; the 18-3545 is the correct 130 degree replacement for the listed Evinrude and Johnson models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a gasket included with the 18-3545 thermostat?\u003c\/strong\u003e The listing covers the thermostat itself, part number 18-3545, rated to open at 130 degrees Fahrenheit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use a different temperature rated thermostat on my Evinrude or Johnson outboard?\u003c\/strong\u003e The 18-3545 is specifically rated at 130 degrees Fahrenheit to match the original equipment specification for the E200\/E225\/E250 and J200\/J225\/J250 models; using a different rating is not covered by this part.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988152955099,"sku":"SIE-18-3545","price":20.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3545_lg__70962.1558126349.500.750.jpg?v=1785188050","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-thermostat-130-degree-for-evinrude-johnson-200-225-250-hp-outboards-replaces-omc-5001036-sierra-18-3545","provider":"Good Vibes Marina","version":"1.0","type":"link"}
