Built from brass for reliable electrical conductivity and corrosion resistance in the marine environment, this terminal is the connection point where ignition wire meets the spark plug boot, completing the circuit that fires the spark plug. Because it comes packaged in a quantity of 10, it is well suited for shops and boat owners servicing multiple cylinders or keeping spares on hand for ignition wire repairs and rebuilds.\u003c\/p\u003e\u003cp\u003eSierra engineers its ignition parts to meet or exceed the original equipment they replace, and this terminal is built to withstand the vibration, heat, and moisture exposure typical of outboard engine compartments. It is a direct equivalent for several OEM terminal numbers used across outboard and sterndrive ignition systems, making it a straightforward replacement when rebuilding ignition wire assemblies or repairing a damaged terminal connection.\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 18-5224-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 10 terminals per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282164911\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Ignition wire terminal for outboard motors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned to fit outboard motor ignition wire applications.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson\/Evinrude 510364\u003c\/li\u003e\n\u003cli\u003eMercury Marine 20121\u003c\/li\u003e\n\u003cli\u003eMercury Marine 8M0084600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow many terminals come in the Sierra 18-5224-9 package?\u003c\/strong\u003e The Sierra 18-5224-9 is sold as a package of 10 spark plug wire terminals, making it convenient for servicing an entire outboard motor's ignition wiring or keeping spares on hand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-5224-9 terminal made of?\u003c\/strong\u003e It is made of brass, which provides good electrical conductivity and resists corrosion in the marine environment where ignition components are exposed to moisture.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-5224-9 terminal replace?\u003c\/strong\u003e It replaces Johnson\/Evinrude 510364, Mercury Marine 20121, and Mercury Marine 8M0084600, so it can be used as a direct equivalent for any of those OEM terminal numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5224-9 genuine Sierra or aftermarket?\u003c\/strong\u003e It is a genuine Sierra part, manufactured by Sierra as an aftermarket replacement engineered to meet or exceed the original equipment terminal it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is each spark plug wire terminal?\u003c\/strong\u003e Each 18-5224-9 terminal measures 0.39 x 0.39 x 0.39 inches, a compact size that fits onto ignition wire before the spark plug boot is attached.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5224-9 package weigh?\u003c\/strong\u003e The package of 10 Sierra 18-5224-9 terminals weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a spark plug wire terminal used for?\u003c\/strong\u003e A spark plug wire terminal, like the Sierra 18-5224-9, connects ignition wire to a spark plug boot, forming the electrical connection needed to deliver spark to the plug on an outboard motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5224-9 come with installation instructions or crimping tools?\u003c\/strong\u003e The package contains only the brass terminals themselves;
