The kit is centered on a contact (points) set and a matching condenser, the two wear items that most commonly cause hard starting, misfiring, or a rough idle as an outboard's ignition ages. Sierra manufactures the kit to meet or exceed original equipment quality, and it is designed as a direct equivalent to the OEM tune-up kit these engines originally shipped with, so it drops into the same ignition service points without modification.\u003c\/p\u003e\u003cp\u003eInside the kit you get a contact set and a Sierra 18-5199 condenser, letting you replace both critical ignition wear parts in a single service instead of sourcing them separately. This keeps the ignition timing and dwell consistent with OEM specifications, which is important for reliable spark and smooth running on points-type Johnson\/Evinrude outboards. The components are made of a plastic, metal, and composite construction consistent with OEM points-and-condenser hardware, and the kit is packaged as a complete 1-count service unit ready for installation.\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 18-5011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Tune-Up Kit (Contact Set and Condenser)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 172521\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContains:\u003c\/strong\u003e Contact Set (O.E.# 580148, Qty 2); Condenser, Sierra 18-5199 (O.E.# 580321, Qty 1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic, Metal, Composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e Outboard Motor Maintenance and Repair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282259273\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThe Sierra 18-5011 Tune Up Kit is designed for Johnson\/Evinrude outboard motors using breaker-point ignition components that match OEM part 172521.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e172521\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5011 Tune Up Kit include?\u003c\/strong\u003e The kit includes a contact (points) set and a Sierra 18-5199 condenser, the two core ignition wear items needed for a breaker-point tune-up on a Johnson\/Evinrude outboard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-5011 kit replace?\u003c\/strong\u003e Sierra 18-5011 replaces OEM part number 172521.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this kit fit any outboard motor?\u003c\/strong\u003e No, the Sierra 18-5011 Tune Up Kit is designed specifically for Johnson\/Evinrude outboard motors that use breaker-point ignition systems; always confirm the original part matches 172521 before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5011 Tune Up Kit weigh?\u003c\/strong\u003e It weighs 0.09 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the condenser included the same as buying it separately?\u003c\/strong\u003e Yes, the condenser packaged in the 18-5011 kit is the Sierra 18-5199 condenser (O.E.# 580321), the same part sold on its own.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the quantity of contact points in the kit?\u003c\/strong\u003e The contact set portion of the 18-5011 kit is supplied in a quantity of 2 (O.E.# 580148).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the tune-up kit components made from?\u003c\/strong\u003e The Sierra 18-5011 components are made of plastic, metal, and composite materials, consistent with standard points-and-condenser ignition hardware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-5011 a genuine Sierra part or aftermarket equivalent?\u003c\/strong\u003e It is a Sierra-manufactured tune-up kit built to meet or exceed original equipment quality as a direct equivalent to OEM part 172521, not a rebranded OEM part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms indicate I need this tune-up kit?\u003c\/strong\u003e Hard starting, misfiring, or a rough idle on a points-type Johnson\/Evinrude outboard often point to worn contact points or a failing condenser, the two items replaced by the Sierra 18-5011 kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many pieces come in the Sierra 18-5011 kit?\u003c\/strong\u003e The kit is sold as a single 1-count tune-up kit containing the contact set and condenser components needed for the service.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988199125211,"sku":"SIE-18-5011","price":16.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5011_lg__79902.1558126919.500.750.jpg?v=1785188759","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5011-tune-up-kit-for-johnson-evinrude-outboards-replaces-omc-172521-contact-set-condenser","provider":"Good Vibes Marina","version":"1.0","type":"link"}
