The power pack is a core component of the capacitor discharge (CD) ignition circuit, working alongside the stator, trigger, and coils to generate and time the spark that fires each cylinder. When a power pack begins to fail, common symptoms include hard starting, misfiring, rough idle, loss of power at higher RPM, or a complete no-spark condition, so replacing it with a correctly matched unit restores reliable ignition timing and spark output. This unit is designated for CD3\/6 applications and is intended as a direct replacement for the ignition power pack in that 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 18-99346\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Johnson Evinrude Power Pack CD3\/6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Power Packs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282398477\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.58 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99346 power pack used for?\u003c\/strong\u003e The Sierra 18-99346 is a power pack for Johnson Evinrude CD3\/6 outboard ignition systems, supplying the timed electrical discharge that fires the ignition coils.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich ignition system does part number 18-99346 fit?\u003c\/strong\u003e Part number 18-99346 is designated for the Johnson Evinrude CD3\/6 capacitor discharge ignition system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99346 power pack weigh?\u003c\/strong\u003e The Sierra 18-99346 power pack weighs 0.58 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-99346 power pack?\u003c\/strong\u003e The UPC for the Sierra 18-99346 Johnson Evinrude CD3\/6 power pack is 808282398477.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the symptoms of a failing power pack on a CD3\/6 ignition system?\u003c\/strong\u003e Hard starting, misfiring, rough idle, loss of power at higher RPM, or no spark at all are typical signs that the power pack in a CD3\/6 ignition system needs replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-99346 an original equipment part or an aftermarket part?\u003c\/strong\u003e The 18-99346 is sold under the Sierra brand as a power pack for the Johnson Evinrude CD3\/6 ignition system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the power pack come with the stator or ignition coils?\u003c\/strong\u003e No, the Sierra 18-99346 is the power pack component only; it does not include the stator, trigger, or ignition coils used elsewhere in the CD3\/6 system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the power pack be installed without special tools?\u003c\/strong\u003e The Sierra 18-99346 power pack mounts to the ignition system wiring harness of the CD3\/6 setup using standard hand tools and connectors already present on the outboard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the 18-99346?\u003c\/strong\u003e The 18-99346 is listed in the Evinrude Outboard Power Packs category as an ignition component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace a power pack instead of the whole ignition system?\u003c\/strong\u003e If diagnosis points specifically to the power pack rather than the stator or coils, replacing just the Sierra 18-99346 power pack restores CD3\/6 ignition function without the added cost of replacing the entire ignition system.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988442198235,"sku":"SIE-18-99346","price":144.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-113-2537_lg__45311.1558114084.500.750.jpg?v=1785329177","url":"https:\/\/www.goodvibesmarina.com\/products\/johnson-evinrude-cd3-cd6-ignition-power-pack-sierra-18-99346-outboard-replacement-module","provider":"Good Vibes Marina","version":"1.0","type":"link"}
