It is designed as a direct upgrade for the ignition system on 1995-2006 4-cylinder engines, replacing the original power pack with a digital optical unit for more consistent spark timing and reliable starting. The kit is a complete package rather than a single part, and includes the power pack along with the additional components needed to complete the ignition upgrade, so the correct mating hardware is on hand at install time.\u003c\/p\u003e\u003cp\u003eThis kit fits 1995-2006 Johnson\/Evinrude 4-cylinder outboards, including 80 JET, 90, 100, 105 Comm, and 115 HP models. It replaces several original Johnson\/Evinrude part numbers, making it a straightforward swap for boat owners whose original power pack has failed or is due for a reliability upgrade. Buyers should confirm the exact engine model and original part number before ordering to ensure correct fitment.\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 18-99170\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 7 x 9 x 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.92 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282393717\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Type:\u003c\/strong\u003e Digital Optical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Configuration:\u003c\/strong\u003e 4 Cylinder\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude 4 Cylinder, 1995-2006: 80 JET, 90, 100, 105 Comm, 115 HP\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e765386\u003c\/li\u003e\n\u003cli\u003e586015\u003c\/li\u003e\n\u003cli\u003e586098\u003c\/li\u003e\n\u003cli\u003e586292\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-99170 power pack kit fit?\u003c\/strong\u003e The Sierra 18-99170 kit fits 1995-2006 Johnson\/Evinrude 4-cylinder outboards, specifically the 80 JET, 90, 100, 105 Comm, and 115 HP models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does this kit replace?\u003c\/strong\u003e Kit 18-99170 replaces original Johnson\/Evinrude part numbers 765386, 586015, 586098, and 586292.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99170 power pack kit weigh?\u003c\/strong\u003e It weighs 1.92 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this power pack kit?\u003c\/strong\u003e The kit measures 7 x 9 x 2.5 inches as packaged.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a digital or analog ignition upgrade?\u003c\/strong\u003e Sierra 18-99170 is a digital optical power pack, an upgrade over the original analog-style ignition module on these Johnson\/Evinrude 4-cylinder engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the kit include everything needed for installation?\u003c\/strong\u003e Yes, 18-99170 is sold as a complete kit with the power pack and the additional components required to complete the ignition upgrade, not just a single loose part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this work on a 2-cylinder or V6 Johnson\/Evinrude motor?\u003c\/strong\u003e No, the 18-99170 kit is designed specifically for 4-cylinder Johnson\/Evinrude outboards in the 1995-2006 80 JET, 90, 100, 105 Comm, and 115 HP range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use my original OEM part number to confirm fitment before ordering?\u003c\/strong\u003e Yes, cross-check your engine's original part number against 765386, 586015, 586098, or 586292, which the 18-99170 kit is built to replace.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy upgrade to a digital optical power pack instead of replacing with the original style?\u003c\/strong\u003e The 18-99170 digital optical design gives more consistent ignition timing and reliability compared to the original power pack it replaces on these 4-cylinder Johnson\/Evinrude engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the box with the 18-99170 kit?\u003c\/strong\u003e The kit includes the power pack unit along with the additional mounting and wiring components needed to complete the ignition upgrade on the 4-cylinder Johnson\/Evinrude engines it fits.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988438135003,"sku":"SIE-18-99170","price":353.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-113-6292K1_lg__66498.1722498783.500.750.jpg?v=1785188306","url":"https:\/\/www.goodvibesmarina.com\/products\/optical-ignition-power-pack-kit-for-johnson-evinrude-4-cylinder-90-115-hp-outboards-1995-2006-replaces-oem-586292-sierra-18-99170","provider":"Good Vibes Marina","version":"1.0","type":"link"}
