It supplies the high-voltage spark needed to fire the spark plugs, and is a common wear item on outboard ignition systems where coils weaken or fail over time and cause misfires, hard starting, or a no-spark condition. The coil uses a male connector for a bolt-on installation, replacing the original unit without modification to the ignition harness. It measures 3 inches long, 3 inches wide, and 2 inches high, and weighs 0.356 pounds, making it a compact, direct-fit replacement sized to match the factory mounting location. This coil cross-references to Sierra part number 18-5179 and GLM part number 72010, so it is compatible with ignition systems calling for either of those numbers. Because ignition coils are wear parts, replacing a weak or failed coil with a properly matched unit like the 300-01991 restores reliable spark output and helps the outboard start and run consistently.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Engineered Marine Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 300-01991\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840080413303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.356 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Gender:\u003c\/strong\u003e Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Type:\u003c\/strong\u003e Bolt-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutboard Fitment:\u003c\/strong\u003e Evinrude\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Reference (Sierra):\u003c\/strong\u003e 18-5179\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Reference (GLM):\u003c\/strong\u003e 72010\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eEvinrude outboard motors.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eSierra 18-5179, GLM 72010\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 300-01991 ignition coil used for?\u003c\/strong\u003e The Engineered Marine Products 300-01991 is an ignition coil for Evinrude outboard motors, generating the high-voltage spark needed to fire the spark plugs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 300-01991 coil cross-reference to a Sierra part number?\u003c\/strong\u003e Yes, the 300-01991 coil cross-references to Sierra part number 18-5179.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a GLM equivalent number for this coil?\u003c\/strong\u003e Yes, the 300-01991 corresponds to GLM part number 72010.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 300-01991 ignition coil?\u003c\/strong\u003e The coil measures 3 inches long, 3 inches wide, and 2 inches high.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 300-01991 coil weigh?\u003c\/strong\u003e It weighs 0.356 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of connector does this coil use?\u003c\/strong\u003e The 300-01991 ignition coil has a male connector.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 300-01991 a bolt-on replacement?\u003c\/strong\u003e Yes, the Engineered Marine Products 300-01991 is a bolt-on installation, so it fits into the factory mounting location without modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard brand is the 300-01991 coil designed for?\u003c\/strong\u003e This coil is designed for Evinrude outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 300-01991 a genuine or aftermarket coil?\u003c\/strong\u003e The 300-01991 is manufactured by Engineered Marine Products as a direct-fit aftermarket replacement coil, cross-referenced to Sierra 18-5179 and GLM 72010.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat signs indicate my outboard's ignition coil needs replacement?\u003c\/strong\u003e Misfires, hard starting, or a no-spark condition are common signs of a failing ignition coil; installing a replacement like the 300-01991 restores spark output on Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 300-01991?\u003c\/strong\u003e The order includes one Engineered Marine Products 300-01991 ignition coil.\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":48991284429019,"sku":"EMP-300-01991","price":30.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/EMP-300-01991-BRP-Ignition-Coil__64331.1722503753.500.750.jpg?v=1785188358","url":"https:\/\/www.goodvibesmarina.com\/products\/emp-300-01991-marine-ignition-coil-for-evinrude-johnson-outboards-replaces-sierra-18-5179","provider":"Good Vibes Marina","version":"1.0","type":"link"}
