Rather than a fixed-length pre-terminated wire, the kit is built around a 25 foot roll of 7mm Hypalon ignition wire with a metallic core, paired with a large assortment of three different end fittings so you can cut the wire to the exact length each cylinder requires and terminate it with the correct fitting for your engine. This makes the kit useful for replacing cracked, brittle, or misfiring ignition wires on multi-cylinder outboards without having to source individual pre-made leads.\u003c\/p\u003e\u003cp\u003eThe Hypalon jacket is a synthetic rubber compound chosen for its resistance to heat, oil, and the harsh marine environment, while the metallic core is designed to carry ignition voltage reliably to the spark plugs. Because the kit supplies bulk wire and multiple fitting sizes rather than one fixed harness, it is well suited to shops and owners who need to service more than one cylinder or more than one engine from a single kit. The Sierra 18-5225 directly replaces Mercury ignition wire kits 84-99215A26 and 84-813706A26.\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 18-5225\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Spark Plug Wire Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Length:\u003c\/strong\u003e 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter:\u003c\/strong\u003e 7 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Material:\u003c\/strong\u003e Hypalon jacket with metallic core\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Fittings:\u003c\/strong\u003e Large assortment of three different sizes to fit outboard motors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.55 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned to fit outboard motors that use the Mercury ignition wire kits listed below.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 84-99215A26\u003c\/li\u003e\n\u003cli\u003eMercury 84-813706A26\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5225 Spark Plug Wire Kit include?\u003c\/strong\u003e The kit includes a 25 foot roll of 7mm Hypalon ignition wire with a metallic core, plus a large assortment of three different end fittings so you can build wires to fit outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the ignition wire in this kit?\u003c\/strong\u003e The wire supplied in the Sierra 18-5225 kit is 7 millimeters in diameter and comes as a 25 foot roll, letting you cut leads to the length each cylinder needs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the wire jacket made of?\u003c\/strong\u003e The 18-5225 kit uses 7mm Hypalon ignition wire with a metallic core, a synthetic rubber jacket chosen for durability in the marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does the Sierra 18-5225 replace?\u003c\/strong\u003e This kit replaces Mercury ignition wire kits 84-99215A26 and 84-813706A26.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this kit fit my specific outboard motor?\u003c\/strong\u003e The Sierra 18-5225 is built to fit outboard motors that originally used Mercury ignition wire kits 84-99215A26 or 84-813706A26; the assortment of three end fitting sizes is provided to match different outboard applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the kit come with pre-cut, terminated wires?\u003c\/strong\u003e No. The 18-5225 supplies a 25 foot roll of bulk 7mm Hypalon ignition wire along with an assortment of end fittings, so wires are cut and terminated to the length and fitting needed for each cylinder.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much wire is in the Sierra 18-5225 kit?\u003c\/strong\u003e There are 25 feet of 7mm Hypalon ignition wire included in the kit, enough to build multiple spark plug leads.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many end fitting sizes come with the kit?\u003c\/strong\u003e The Sierra 18-5225 includes a large assortment of three different end fitting sizes to fit outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5225 kit weigh?\u003c\/strong\u003e The kit weighs 0.55 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5225 an OEM Mercury part or an aftermarket replacement?\u003c\/strong\u003e It is a Sierra aftermarket kit engineered to replace Mercury ignition wire kits 84-99215A26 and 84-813706A26.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this kit be used on more than one cylinder or engine?\u003c\/strong\u003e Because the 18-5225 provides a full 25 foot roll of wire and multiple end fitting sizes rather than a single pre-made lead, it can be used to service more than one cylinder or spark plug wire from a single kit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988202205403,"sku":"SIE-18-5225","price":32.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-5225__67788.1739458813.500.750.jpg?v=1785188550","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5225-marine-spark-plug-wire-kit-replaces-mercury-84-99215a26-84-813706a26-25-ft-7mm-hypalon-ignition-wire-for-outboard-motors","provider":"Good Vibes Marina","version":"1.0","type":"link"}
