A stator generates the AC current that the outboard's rectifier converts to charge the battery and power the electrical system, making it a core component of the engine's charging circuit. The Sierra 18-5870 is built to meet or exceed the quality and output of the original equipment stator it replaces, using a machined exterior construction designed to hold up to the vibration, heat, and moisture of a harsh marine environment.\u003c\/p\u003e\u003cp\u003eThis stator fits Mercury 90 HP 3 cylinder electric models, Mercury 100 HP 4 cylinder models, Mercury 115 HP 4 cylinder electric models, and Mercury 125 HP 4 cylinder models, including both domestic and Belgium-built serial number ranges. It is not intended for 4 cylinder models equipped with a voltage regulator, which use a separate Sierra part number. The 18-5870 cross-references to a range of Mercury, Chrysler, CDI, and Mallory OEM stator numbers, so it can be used to replace any of those parts on a covered engine. Always confirm the serial number range and engine configuration of your outboard before ordering to ensure correct fitment.\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 18-5870\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard Stators \u0026amp;
