It measures 12 inches long and is configured with a 90 degree male connector on the distributor end and a 90 degree female connector on the coil end, matching the exact routing angle these engines require so the lead sits flush without kinking or straining the terminals.\u003c\/p\u003e\u003cp\u003eCopper construction provides reliable electrical conductivity for consistent spark delivery, which is essential for dependable ignition performance in a marine environment. Because coil leads are a wear item exposed to heat and vibration, replacing a cracked or corroded lead with this Sierra 18-28100 helps restore proper coil-to-distributor connection and ignition reliability. Note that Sierra also offers 18-28101 (female distributor end, female coil end) and 18-28102 (male distributor end, 180 degree male coil end) as separate part numbers, so confirm the connector configuration needed before ordering.\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 18-28100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Coil Lead Wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistributor End Connector:\u003c\/strong\u003e 90 degree male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil End Connector:\u003c\/strong\u003e 90 degree female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 1.45 x 5.85 x 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282341466\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-28100 coil lead wire used for?\u003c\/strong\u003e It carries current from the ignition coil to the distributor on marine engines using a points-and-coil ignition system, connecting the coil to the distributor with a 90 degree male end and a 90 degree female end.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long is the 18-28100 coil lead?\u003c\/strong\u003e The lead measures 12 inches long, running from the coil terminal to the distributor terminal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat connector configuration does the 18-28100 have?\u003c\/strong\u003e It has a 90 degree male connector on the distributor end and a 90 degree female connector on the coil end.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the coil lead made of?\u003c\/strong\u003e The Sierra 18-28100 is made of copper for reliable electrical conductivity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-28100 coil lead weigh?\u003c\/strong\u003e It weighs 0.13 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-28100 the same as the 18-28101 coil lead?\u003c\/strong\u003e No. The 18-28100 has a 90 degree male distributor end and 90 degree female coil end, while the 18-28101 has a female distributor end and a 90 degree female coil end.
