It is molded from durable black plastic designed to seal the manifold drain port securely, helping prevent freeze damage and corrosion-related leaks when the engine is winterized or drained for service. As a genuine Sierra part, it is built to meet or exceed the quality of the original equipment plug it replaces.\u003c\/p\u003e\u003cp\u003eThis drain plug is a straightforward, one-piece replacement part sold individually, making it an easy and affordable fix when an original Mercruiser drain plug is lost, cracked, or no longer seals properly. Because it is cross-referenced to the Mercruiser 22-806608A1 and 22-806608A02 numbers, boat owners and technicians can confirm fitment by matching the old part number before ordering. Sierra part 18-4226 is a reliable choice for routine engine maintenance, winterization, and exhaust manifold servicing.\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 18-4226\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Drain Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.27 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282125158\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 22-806608A1, 22-806608A02\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Mercruiser Exhaust Manifold\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Mercruiser exhaust manifold applications using drain plug numbers 22-806608A1 or 22-806608A02.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e22-806608A1\u003c\/li\u003e\n\u003cli\u003e22-806608A02\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the Sierra 18-4226 drain plug replace?\u003c\/strong\u003e The Sierra 18-4226 drain plug replaces Mercruiser part numbers 22-806608A1 and 22-806608A02.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-4226 drain plug made of?\u003c\/strong\u003e It is made of black plastic, molded to seal the drain port of a Mercruiser exhaust manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-4226 drain plug weigh?\u003c\/strong\u003e It weighs 1.27 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e Sierra 18-4226 is a Sierra-brand replacement part built to meet or exceed the quality of the original Mercruiser drain plug it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this drain plug used for?\u003c\/strong\u003e It is used to seal the drain port on Mercruiser exhaust manifolds, commonly removed during winterization or engine maintenance to drain water from the manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many drain plugs come in a package?\u003c\/strong\u003e The Sierra 18-4226 is sold as a single drain plug, one count per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-4226 drain plug?\u003c\/strong\u003e It is black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if 18-4226 is the correct drain plug for my engine?\u003c\/strong\u003e Check the part number stamped on your existing drain plug; if it reads 22-806608A1 or 22-806608A02, the Sierra 18-4226 is the correct replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-4226 include any other hardware in the box?\u003c\/strong\u003e No, it includes only the drain plug itself; no additional hardware is included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra part number for this drain plug?\u003c\/strong\u003e The part number is 18-4226.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988172058843,"sku":"SIE-18-4226","price":3.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/88911_18-4226front__50468.1753840680.500.750.jpg?v=1785188449","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-4226-marine-drain-plug-for-mercruiser-replaces-22-806608a1-22-806608a02","provider":"Good Vibes Marina","version":"1.0","type":"link"}
