It delivers a coil resistance of 3.0 ohms, with a primary resistance of 1.4 ohms (plus or minus 15 percent) and a secondary resistance of 8 ohms (plus or minus 20 percent), producing the spark energy needed for reliable ignition in a marine environment. The coil uses a male connector for straightforward wiring and is a bolt-on installation, letting it mount in place of the original coil without modification. Sierra manufactures this coil to meet or exceed the performance of the original equipment part it replaces, making it a direct functional replacement rather than a generic substitute. Housed in a compact 3.5 x 3.5 x 7 inch body, it is sized to fit into the same mounting locations as the original coil it replaces. This coil is intended for applications that specifically call for an internal-resistor ignition coil rather than an externally resisted setup, so confirming that requirement before ordering will ensure correct electrical compatibility.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
