The gasket seals the thermostat housing to the cylinder head, maintaining proper cooling system pressure and preventing water leakage around the thermostat during operation. It is round in shape with a multi-colored appearance and is built to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eThis gasket is designed for Johnson\/Evinrude outboards rated at 200 HP (1977-83) and 235 HP (1978-85). It is also cross-referenced to several other aftermarket and OEM part numbers, making it a straightforward swap for boat owners and marine technicians sourcing a replacement gasket by an equivalent part number. Each pack ships as a lightweight, low-cost maintenance item intended to be replaced any time the thermostat housing is removed or serviced, ensuring a proper seal and preventing coolant leaks after reassembly.\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 18-0182-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Thermostat Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Multi-colored\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282161484\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e GLM 30610, Evinrude\/Johnson 310058, Mallory 9-60002, Mercury 27-62386, 27-62386001\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson\/Evinrude 200 HP outboards, 1977-83\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 235 HP outboards, 1978-85\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGLM 30610\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 310058\u003c\/li\u003e\n\u003cli\u003eMallory 9-60002\u003c\/li\u003e\n\u003cli\u003eMercury 27-62386\u003c\/li\u003e\n\u003cli\u003eMercury 27-62386001\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-0182-9 thermostat gasket fit?\u003c\/strong\u003e It fits Johnson\/Evinrude outboards rated at 200 HP built from 1977-83 and 235 HP built from 1978-85.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets are in one package?\u003c\/strong\u003e The Sierra 18-0182-9 comes as a pack of 2 thermostat gaskets, giving you a spare or enough for a two-bank service job.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0182-9 interchangeable with other brands?\u003c\/strong\u003e Yes, it cross-references to GLM 30610, Evinrude\/Johnson 310058, Mallory 9-60002, and Mercury 27-62386 \/ 27-62386001, so it can be ordered under any of those numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape and color is this gasket?\u003c\/strong\u003e The 18-0182-9 gasket is round in shape with a multi-colored appearance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-0182-9 pack weigh?\u003c\/strong\u003e The pack weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine OEM part or an aftermarket replacement?\u003c\/strong\u003e The Sierra 18-0182-9 is an aftermarket thermostat gasket built to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0182-9 thermostat gasket?\u003c\/strong\u003e The UPC is 808282161484.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-0182-9 work on a 225 HP Johnson\/Evinrude outboard?\u003c\/strong\u003e No, the fitment for the 18-0182-9 covers 200 HP (1977-83) and 235 HP (1978-85) models; other horsepower and year ranges use a different Sierra thermostat gasket part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes in the box with this purchase?\u003c\/strong\u003e Each order includes 2 Sierra 18-0182-9 thermostat gaskets and nothing else.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Mercury 27-62386 gasket be used in place of the Sierra 18-0182-9?\u003c\/strong\u003e Yes, Mercury 27-62386 (and 27-62386001) is one of the cross-reference numbers for the Sierra 18-0182-9, so either number will get you the same gasket.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988029649115,"sku":"SIE-18-0182-9","price":3.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-0182-9__25311.1722487561.500.750.jpg?v=1785188852","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0182-9-thermostat-gasket-replaces-evinrude-johnson-337068-pack-of-2-for-evinrude-johnson-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
