This engine family requires 3 coils per powerhead, and the 18-5170 is engineered as a drop-in match for that application, restoring correct spark output for reliable starting and smooth running.\u003c\/p\u003e\u003cp\u003eEach coil is cross-referenced to GLM 72060, Evinrude\/Johnson 0583740, Mallory 9-23104, and OMC 583740, so it can be ordered using any of those familiar part numbers. It uses a male-to-female connector and is available as a bolt-on or clip-in installation depending on the engine's mounting configuration. Compact at just 0.39 x 0.39 x 0.39 inches and 0.77 pounds, the 18-5170 is a straightforward maintenance-item replacement for anyone servicing an aging 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 18-5170\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Evinrude\/Johnson 150 HP (1991-2006) and 175 HP (1991-2006)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoils Required Per Engine:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.77 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Gender:\u003c\/strong\u003e Male-to-Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Type:\u003c\/strong\u003e Bolt-On or Clip-In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e GLM 72060, Evinrude\/Johnson 0583740, Mallory 9-23104, OMC 583740\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEvinrude\/Johnson 150 HP, 1991-2006\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 175 HP, 1991-2006\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGLM 72060\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 0583740\u003c\/li\u003e\n\u003cli\u003eMallory 9-23104\u003c\/li\u003e\n\u003cli\u003eOMC 583740\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5170 ignition coil fit?\u003c\/strong\u003e The Sierra 18-5170 is built for Evinrude\/Johnson 150 HP outboards from 1991 to 2006 and 175 HP outboards from 1991 to 2006.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many of these coils does my engine need?\u003c\/strong\u003e Evinrude\/Johnson 150 HP and 175 HP engines covered by the 18-5170 each require 3 coils per powerhead, so most owners replace them as a set.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5170 the same as OMC 583740?\u003c\/strong\u003e Yes, the 18-5170 is cross-referenced to OMC 583740 as well as Evinrude\/Johnson 0583740, GLM 72060, and Mallory 9-23104, so any of those numbers point to the same coil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this ignition coil?\u003c\/strong\u003e The Sierra 18-5170 measures 0.39 x 0.39 x 0.39 inches and weighs 0.77 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of connector does the 18-5170 use?\u003c\/strong\u003e It uses a male-to-female connector configuration for its wiring connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine OEM coil or an aftermarket replacement?\u003c\/strong\u003e The Sierra 18-5170 is an aftermarket replacement coil manufactured to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 18-5170 installed?\u003c\/strong\u003e Depending on the engine setup, the Sierra 18-5170 installs as either a bolt-on or clip-in component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5170 work on a 175 HP Evinrude from the late 1970s?\u003c\/strong\u003e No. The 18-5170 is specified for 175 HP applications from 1991 to 2006; earlier 175 HP model years use different Sierra coil part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes in the box with the 18-5170?\u003c\/strong\u003e Each order includes one Sierra 18-5170 ignition coil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-5170 replace a Mallory 9-23104 coil?\u003c\/strong\u003e Yes, the Sierra 18-5170 is cross-referenced to the Mallory 9-23104 and can be used as a direct equivalent.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988200567003,"sku":"SIE-18-5170","price":40.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5170_lg__94452.1558128652.500.750.jpg?v=1785188093","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5170-ignition-coil-for-evinrude-johnson-omc-outboards-replaces-omc-583740-583298","provider":"Good Vibes Marina","version":"1.0","type":"link"}
