The ignition pack is a core component of the outboard's electronic ignition system, controlling spark timing and delivery to keep the engine firing correctly and running smoothly. As a direct-fit replacement component, it is designed to restore reliable ignition performance on Yamaha 2-cylinder outboards experiencing hard starting, misfiring, stalling, or a complete no-spark condition caused by a failed or failing ignition pack.\u003c\/p\u003e\u003cp\u003eIgnition packs like this one are a common wear item on outboard engines, since they are exposed to constant vibration, heat, and marine moisture. Replacing a worn or failed unit with the Sierra 18-99317 helps restore consistent spark output and dependable engine starting and running characteristics. At a compact 0.4 pounds, it installs in place of the original ignition pack using the existing mounting and wiring connections on applicable Yamaha 2-cylinder outboard models.\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 18-99317\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Yamaha Ignition Pack - 2 Cyl.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Yamaha Outboard CDI \/ Ignition Pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282396145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Yamaha 2-cylinder outboard engines.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-99317 ignition pack do?\u003c\/strong\u003e It controls spark timing and delivery for a Yamaha 2-cylinder outboard's ignition system, and the part number for this ignition pack is 18-99317.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this ignition pack fit my outboard?\u003c\/strong\u003e The 18-99317 ignition pack is built for Yamaha 2-cylinder outboard engines; confirm your engine is a Yamaha 2-cylinder model before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99317 ignition pack weigh?\u003c\/strong\u003e This Sierra ignition pack weighs 0.4 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms indicate the ignition pack needs to be replaced?\u003c\/strong\u003e Hard starting, misfiring, stalling, or a no-spark condition on a Yamaha 2-cylinder outboard are common signs the ignition pack, such as the Sierra 18-99317, has failed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99317 a genuine Yamaha part or aftermarket?\u003c\/strong\u003e The 18-99317 is a Sierra-branded ignition pack designed as a replacement component for Yamaha 2-cylinder outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the ignition pack come with mounting hardware?\u003c\/strong\u003e The listing covers the Yamaha 2-cylinder ignition pack itself, part number 18-99317; no additional components are specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install the 18-99317 ignition pack myself?\u003c\/strong\u003e Installation involves replacing the existing ignition pack using the outboard's original mounting points and wiring connections, though anyone unfamiliar with marine ignition systems should have a qualified marine technician perform the replacement of this Sierra 18-99317 unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-99317 ignition pack?\u003c\/strong\u003e The UPC for this Yamaha 2-cylinder ignition pack is 808282396145.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this ignition pack for a 2-cylinder or a different cylinder count Yamaha outboard?\u003c\/strong\u003e The Sierra 18-99317 is specifically designed for Yamaha 2-cylinder outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does an outboard need a functioning ignition pack?\u003c\/strong\u003e The ignition pack, also called a CDI module, is required to fire the spark plugs at the correct timing; without a working unit like the 18-99317, a Yamaha 2-cylinder outboard will not start or run properly.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988441510107,"sku":"SIE-18-99317","price":205.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-117-696-12_lg__97952.1722508164.500.750.jpg?v=1785329165","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-99317-cdi-ignition-pack-for-2-cylinder-yamaha-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
