Brass construction resists the corrosive effects of raw water and exhaust condensation, making it a durable choice for below-waterline and engine-block drain points. The NPT-threaded end allows it to thread directly into a tapped drain port, while the 1 inch hose end accepts standard marine hose for directing drained water or coolant away from the engine. This drain plug is used in Mercruiser exhaust manifold applications and is a direct replacement for OEM part number 22-807155, letting you restore a factory-fit seal without sourcing the original manufacturer part. Its compact brass body is built to hold up under repeated draining and re-installation, a routine task for winterizing and off-season storage of sterndrive and inboard engines. Whether you are replacing a corroded or stripped original plug or performing scheduled maintenance, this fitting provides a reliable, leak-resistant connection point.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 22-22000-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/4 inch - 14 NPT x 1 inch Hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-Resistant Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Mercruiser Exhaust Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.28 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840080455808\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 22-807155\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUsed in Mercruiser exhaust manifold drain applications.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e22-807155\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the EMP 22-22000-2 drain plug replace?\u003c\/strong\u003e It is a direct replacement for OEM part number 22-807155.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size threads does this drain plug use?\u003c\/strong\u003e The EMP 22-22000-2 uses a 3\/4 inch - 14 NPT thread on one end and a 1 inch hose connection on the other.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this drain plug made of?\u003c\/strong\u003e It is made of corrosion-resistant brass, which holds up well against raw water and exhaust condensation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the EMP 22-22000-2 drain plug weigh?\u003c\/strong\u003e It weighs 0.28 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat application is this drain plug designed for?\u003c\/strong\u003e The 22-22000-2 is used in Mercruiser exhaust manifold drain applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this an OEM or aftermarket part?\u003c\/strong\u003e The EMP 22-22000-2 is an aftermarket brass drain plug engineered to replace OEM number 22-807155 with equivalent fit and function.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this fitting be used with standard marine hose?\u003c\/strong\u003e Yes, the 1 inch hose end of the 22-22000-2 accepts standard 1 inch marine hose.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace a drain plug like this?\u003c\/strong\u003e Drain plugs corrode or crack over time from exposure to raw water and heat cycling, and the EMP 22-22000-2 provides a corrosion-resistant brass replacement for OEM part 22-807155.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the NPT threading seal without additional parts?\u003c\/strong\u003e The 3\/4 inch - 14 NPT threads on the 22-22000-2 are tapered pipe threads designed to seal when properly installed; using thread sealant is standard practice for a leak-free fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this drain plug part of routine winterizing?\u003c\/strong\u003e Yes, drain plugs like the EMP 22-22000-2 are commonly removed and reinstalled during winterizing and off-season draining of exhaust manifolds.\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":48991281053915,"sku":"EMP-22-22000-2","price":3.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/EMP_22-22000-2_Mercury_MerCruiser_Drain_Plug__33349.1739477073.500.750.jpg?v=1785329103","url":"https:\/\/www.goodvibesmarina.com\/products\/mercruiser-exhaust-manifold-drain-plug-replaces-22-806608a1-22-806608a02-marine-engine-cooling-system-drain-plug","provider":"Good Vibes Marina","version":"1.0","type":"link"}
