The stator generates the AC current that feeds the engine's ignition and charging systems, and a worn or failed stator is a common cause of no-spark, weak charging, or intermittent electrical faults on older outboards. This unit is designed as a direct fit for Mercury\/Mariner 115 HP 6 cylinder outboards with engine numbers 5314656 and up, and it cross-references to several widely used OEM and aftermarket part numbers, making it easy to identify as the correct replacement regardless of which number appears on your old unit or your parts diagram.\u003c\/p\u003e\u003cp\u003eConstruction uses a copper alloy winding for consistent electrical output and long service life in the marine environment. The stator ships with an extra black lead that must be connected to engine ground for correct operation; this is a factory-specified wiring detail rather than an optional connection. As a properly fitted replacement, it is designed to meet or exceed the output and durability of the original equipment part it replaces, restoring normal ignition and charging performance without modification to the powerhead.\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 18-5854-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Copper alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Engine mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Horsepower:\u003c\/strong\u003e 115 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Note:\u003c\/strong\u003e Extra black lead connects to engine ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282392482\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury\/Mariner 115 HP, 6 cylinder outboard, engine numbers 5314656 and up\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 398-5454A17\u003c\/li\u003e\n\u003cli\u003eMercury 398-5454A8\u003c\/li\u003e\n\u003cli\u003eCDI 174-5456\u003c\/li\u003e\n\u003cli\u003eMallory 9-25500\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5854-1 stator fit?\u003c\/strong\u003e It fits Mercury\/Mariner 115 HP, 6 cylinder outboard motors with engine numbers 5314656 and up.
