The ignition coil is a core part of the outboard's ignition system, stepping up battery voltage to the level needed to fire the spark plugs and keep the engine running smoothly through the RPM range. Replacing a weak or failed coil with the correct Sierra part restores reliable spark delivery, which shows up as easier starting, smoother idle, and steadier performance under load.\u003c\/p\u003e\u003cp\u003eSierra part 18-5176 is application-specific: it fits Evinrude 150 HP outboards from model years 1979 to 1984 and again in 1988, 155 HP outboards in 1984 and 1988, 175 HP outboards from 1979 to 1983, and 185 HP outboards in 1984. Each of these applications uses a 6-coil setup. Other Evinrude model years in the same horsepower classes use different Sierra coil numbers, so confirming the exact model year against the fitment list below ensures the correct coil is ordered the first time.\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 18-5176\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Ignition Coil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Quantity:\u003c\/strong\u003e 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.41 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999236784\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Evinrude 150 HP (1979-1984, 1988), 155 HP (1984, 1988), 175 HP (1979-1983), 185 HP (1984)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEvinrude 150 HP: 1979-1984 and 1988\u003c\/li\u003e\n\u003cli\u003eEvinrude 155 HP: 1984 and 1988\u003c\/li\u003e\n\u003cli\u003eEvinrude 175 HP: 1979-1983\u003c\/li\u003e\n\u003cli\u003eEvinrude 185 HP: 1984\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5176 ignition coil fit?\u003c\/strong\u003e The Sierra 18-5176 fits Evinrude outboards: 150 HP for model years 1979-1984 and 1988, 155 HP for 1984 and 1988, 175 HP for 1979-1983, and 185 HP for 1984.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many coils come with part number 18-5176?\u003c\/strong\u003e Sierra 18-5176 is used in a 6-coil configuration on all of its listed Evinrude applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5176 ignition coil weigh?\u003c\/strong\u003e The Sierra 18-5176 ignition coil weighs 0.41 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5176 the same coil used on later Evinrude model years?\u003c\/strong\u003e No. Evinrude 150 HP and 175 HP outboards built from 1991 to 2006 use Sierra coil 18-5170 in a 3-coil configuration, and other years in between use Sierra 18-5179, so 18-5176 is specific to the model years listed for this part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-5176 ignition coil?\u003c\/strong\u003e The UPC for the Sierra 18-5176 ignition coil is 030999236784.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMy 1988 Evinrude 150 HP needs a coil, which part number is correct?\u003c\/strong\u003e For a 1988 Evinrude 150 HP outboard, Sierra 18-5176 is the correct ignition coil in the 6-coil configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5176 fit both 155 HP and 185 HP Evinrude engines?\u003c\/strong\u003e Yes, Sierra 18-5176 covers Evinrude 155 HP in 1984 and 1988, and Evinrude 185 HP in 1984, in addition to its 150 HP and 175 HP applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or aftermarket?\u003c\/strong\u003e This is a genuine Sierra ignition coil, part number 18-5176, manufactured by Sierra for the listed Evinrude outboard applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering the 18-5176?\u003c\/strong\u003e Ordering Sierra 18-5176 includes the ignition coil itself, sized for the 6-coil setup used on its listed Evinrude 150, 155, 175, and 185 HP applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy are there different Sierra coil numbers for the same horsepower rating?\u003c\/strong\u003e Evinrude changed ignition coil designs across model years, so the same horsepower rating can require different Sierra part numbers depending on the year; 18-5176 covers the specific years listed for 150, 155, 175, and 185 HP models.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988200468699,"sku":"SIE-18-5176","price":40.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-5176__25706.1722358964.500.750.jpg?v=1785329163","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5176-ignition-coil-kit-for-evinrude-johnson-outboards-replaces-omc-582106-583737","provider":"Good Vibes Marina","version":"1.0","type":"link"}
