It delivers the spark energy the ignition system needs to fire the engine's spark plugs, and each package includes one ignition coil. Sierra builds this coil to meet or exceed the performance of the original equipment part it replaces, making it a straightforward swap for a failing or worn factory coil.\u003c\/p\u003e\u003cp\u003eThe coil is fit specific to the Johnson\/Evinrude outboard engines it is designed for, so buyers should confirm part numbers before ordering to ensure proper fit. It measures 4 x 1.7 x 0.6 inches and uses a screw-in or bolt-on style installation, keeping the replacement process simple for anyone servicing their own outboard ignition system.\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 18-5179-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 4 x 1.7 x 0.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.33 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Type:\u003c\/strong\u003e Screw-In or Bolt-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Ignition Coil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Service Type:\u003c\/strong\u003e PWC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e GLM 72010, Mallory 9-23107, CDI 183-2508, Johnson\/Evinrude 0582508, OMC 582508\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use with Johnson\/Evinrude outboard engines.
