The power pack is the central switching module of a capacitor discharge ignition setup, controlling spark timing and delivery to the engine's cylinders. As an ignition system component, it plays a direct role in reliable starting and smooth running, and is a common replacement part when an outboard develops hard-starting, misfiring, or intermittent ignition symptoms tied to the CD3\/6 system.\u003c\/p\u003e\u003cp\u003eThis part is sold under Sierra part number 18-99323 and is identified by UPC 736983850171. It is intended as a direct fit for Johnson Evinrude outboards equipped with the CD3\/6 power pack ignition arrangement, allowing an owner or technician to replace a failed or aging unit with a like-for-like component rather than sourcing a used original part.\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 18-99323\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Evinrude Outboard Power Pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 736983850171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.64 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson Evinrude outboard engines with CD3\/6 ignition\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eNo OEM cross-reference numbers published for this part\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-99323 power pack fit?\u003c\/strong\u003e The 18-99323 is built for Johnson Evinrude outboard engines that use the CD3\/6 ignition system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a power pack on an outboard engine?\u003c\/strong\u003e A power pack is the ignition control module in a capacitor discharge (CD) ignition system, and on the Johnson Evinrude CD3\/6 setup the Sierra 18-99323 serves as this switching and timing component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99323 power pack weigh?\u003c\/strong\u003e It weighs 0.64 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow can I confirm I am ordering the correct part?\u003c\/strong\u003e Sierra part number 18-99323 and UPC 736983850171 both identify this specific Johnson Evinrude CD3\/6 power pack, so matching either number confirms the correct item.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-99323 a new part or refurbished?\u003c\/strong\u003e The Sierra 18-99323 is sold as a replacement power pack unit for Johnson Evinrude CD3\/6 outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms indicate a power pack needs replacement?\u003c\/strong\u003e Hard starting, misfiring, or intermittent spark on a Johnson Evinrude outboard with CD3\/6 ignition are common signs pointing to the power pack, which the 18-99323 is designed to replace.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99323 include mounting hardware or wiring?\u003c\/strong\u003e The listing covers the Sierra 18-99323 power pack unit itself for Johnson Evinrude CD3\/6 outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this power pack be used on both Johnson and Evinrude branded outboards?\u003c\/strong\u003e Yes, the Sierra 18-99323 is designated for Johnson Evinrude outboards with the CD3\/6 ignition system, covering both brand names under that shared ignition platform.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat ignition system does the CD3\/6 designation refer to?\u003c\/strong\u003e CD3\/6 refers to the capacitor discharge ignition arrangement used on the Johnson Evinrude outboards that the Sierra 18-99323 power pack is built to fit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988441805019,"sku":"SIE-18-99323","price":144.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-113-2817_lg__22909.1558111108.500.750.jpg?v=1785329177","url":"https:\/\/www.goodvibesmarina.com\/products\/power-pack-for-johnson-evinrude-outboards-cd3-cd6-ignition-sierra-18-99323","provider":"Good Vibes Marina","version":"1.0","type":"link"}
