It is designed as a replacement for the original Mercury Marine sensor used in Thunderbolt ignition (1981-1997) applications with nut connectors, restoring reliable spark timing signal to the ignition module.\u003c\/p\u003e\u003cp\u003eThe sensor uses a flange mount design with a push-pull output type, and its housing is constructed of ceramic and metal for durability in a marine engine environment. It is a compact, discreet-style component measuring 0.39 x 0.39 x 0.39 inches, making it a precise, drop-in replacement rather than a universal part. The kit includes one ignition sensor.\u003c\/p\u003e\u003cp\u003eThis sensor is intended for GM V-6 \u0026amp; V-8 engines with Thunderbolt ignition, and it replaces the Mercury Marine 87-861780A2, 87-861780Q4, and 87-892150A02 ignition sensors.\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 18-5116-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Ignition Sensor Kit\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 0.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Ceramic, Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Flange Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Type:\u003c\/strong\u003e Push-Pull\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Ignition Sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282197926\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282197926\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eGM V-6 \u0026amp; V-8 engines with Thunderbolt ignition (1981-1997), nut connectors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e87-861780A2\u003c\/li\u003e\n\u003cli\u003e87-861780Q4\u003c\/li\u003e\n\u003cli\u003e87-892150A02\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5116-1 ignition sensor fit?\u003c\/strong\u003e This sensor fits GM V-6 \u0026amp; V-8 marine engines equipped with Thunderbolt ignition (1981-1997) using nut connectors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-5116-1 replace?\u003c\/strong\u003e The Sierra 18-5116-1 replaces Mercury Marine ignition sensors 87-861780A2, 87-861780Q4, and 87-892150A02.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5116-1 an OEM Mercury Marine part or aftermarket?\u003c\/strong\u003e It is a Sierra aftermarket replacement sensor built to match the fit and function of the original Mercury Marine 87-861780A2 and 87-861780Q4 sensors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this ignition sensor?\u003c\/strong\u003e The Sierra 18-5116-1 measures 0.39 x 0.39 x 0.39 inches, a compact flange-mount unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5116-1 ignition sensor weigh?\u003c\/strong\u003e It weighs 0.23 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the ignition sensor made from?\u003c\/strong\u003e The 18-5116-1 sensor housing is made of ceramic and metal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the sensor mount and connect?\u003c\/strong\u003e It uses a flange mount design with a push-pull output type, matching the nut-connector setup used on Thunderbolt ignition systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when you order the 18-5116-1?\u003c\/strong\u003e The kit includes one ignition sensor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this sensor work on non-GM Thunderbolt ignition engines?\u003c\/strong\u003e No, the 18-5116-1 is specified for GM V-6 \u0026amp; V-8 engines with Thunderbolt ignition (1981-1997).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the 18-5116-1 to replace a failed OEM sensor without other modifications?\u003c\/strong\u003e Yes, since it is built as a direct replacement for the Mercury Marine 87-861780A2, 87-861780Q4, and 87-892150A02 sensors on the same Thunderbolt ignition system.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988199813339,"sku":"SIE-18-5116-1","price":74.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Untitled-1__66394.1753840681.500.750.jpg?v=1785188006","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5116-1-ignition-coil-sensor-for-delco-est-v6-v8-marine-engines-replaces-811639","provider":"Good Vibes Marina","version":"1.0","type":"link"}
