The power pack is the electronic component of the CD2 ignition system that manages spark timing and delivers the charge to the coils, and a failing unit is a common cause of no-spark, misfire, or hard-starting complaints on outboards using this ignition type. Replacing the power pack restores reliable spark generation without requiring a full ignition system overhaul.\u003c\/p\u003e\u003cp\u003eThis unit is sold under Sierra's marine parts line as a direct component replacement in the Evinrude Outboard Power Packs category, and is built to the light, compact form factor typical of CD2 power packs so it mounts in the same location as the original unit.\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 18-99312\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Power Packs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Type:\u003c\/strong\u003e CD2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282395452\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99312 power pack used for?\u003c\/strong\u003e It is a CD2-type power pack, the electronic ignition module that controls spark timing and delivers the charge to the coils on Johnson and Evinrude outboard motors equipped with this ignition system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-99312 a genuine Sierra part or aftermarket equivalent?\u003c\/strong\u003e The 18-99312 is a Sierra-branded power pack, sold as a direct replacement component within Sierra's Evinrude Outboard Power Packs line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the symptoms of a failing power pack that this part fixes?\u003c\/strong\u003e A failing CD2 power pack typically causes no-spark conditions, intermittent misfire, or hard starting; installing the Sierra 18-99312 replaces the ignition module responsible for generating and timing the spark.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-99312 power pack weigh?\u003c\/strong\u003e The Sierra 18-99312 power pack weighs 0.6 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat ignition system does the 18-99312 belong to?\u003c\/strong\u003e The 18-99312 is a CD2 (capacitor discharge) type power pack, designed as the electronic ignition control module for that system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering part number 18-99312?\u003c\/strong\u003e Ordering 18-99312 gets you the single Sierra CD2 power pack unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-99312 be installed as a direct swap for the original power pack?\u003c\/strong\u003e Yes, the Sierra 18-99312 is built as a component replacement power pack, intended to install in place of the original CD2 unit it is replacing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra list OEM cross-reference numbers for the 18-99312?\u003c\/strong\u003e No specific OEM cross-reference numbers are published for the Sierra 18-99312 power pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category does the Sierra 18-99312 fall under?\u003c\/strong\u003e The 18-99312 is listed in the Evinrude Outboard Power Packs category, reflecting its use as an ignition power pack for Johnson and Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the UPC for the Sierra 18-99312 power pack available?\u003c\/strong\u003e Yes, the Sierra 18-99312 power pack has UPC 808282395452.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988441477339,"sku":"SIE-18-99312","price":140.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-113-2474_lg__21928.1558114036.500.750.jpg?v=1785329178","url":"https:\/\/www.goodvibesmarina.com\/products\/power-pack-cd2-for-johnson-evinrude-outboards-sierra-18-99312-cd-ignition-module","provider":"Good Vibes Marina","version":"1.0","type":"link"}
