The stator is the charging component inside the flywheel housing that generates AC current as the flywheel spins, feeding the rectifier to keep the battery charged and supply power to the ignition system. This coil is designed as a direct replacement for the OEM unit on covered Johnson\/Evinrude outboards, restoring reliable charging output when the original stator has failed, weakened, or shows signs of insulation breakdown.\u003c\/p\u003e\u003cp\u003eWeak or failed charging output is a common cause of a dead battery or an engine that runs fine but won't keep its battery topped off underway. Installing a fresh stator coil like the 18-99231 addresses this at the source rather than masking the symptom with a bigger battery or an external charger. The unit is sized to match the 2-cylinder charging system architecture used across a range of Johnson\/Evinrude horsepower ratings, so it bolts into the same mounting location as the original part it replaces.\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 18-99231\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Stator Charging Coil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinders:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e 5 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine Brand:\u003c\/strong\u003e Johnson\/Evinrude\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment Years:\u003c\/strong\u003e 1977-2007\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower Range:\u003c\/strong\u003e 4 to 60 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282393984\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboard engines, 4 to 60 HP, model years 1977-2007\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e582926\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-99231 stator coil fit?\u003c\/strong\u003e The Sierra 18-99231 fits 2-cylinder Johnson\/Evinrude outboard engines from 4 to 60 HP, model years 1977-2007.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99231 a direct replacement for OEM part 582926?\u003c\/strong\u003e Yes, the Sierra 18-99231 replaces OEM number 582926 and installs in the same location as the original stator.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many amps does this stator coil put out?\u003c\/strong\u003e The 18-99231 is a 5 amp stator charging coil, matching the output rating of the 2-cylinder charging system it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a stator coil actually do on an outboard?\u003c\/strong\u003e A stator coil sits inside the flywheel housing and generates AC current as the flywheel rotates, which is then fed to the rectifier to charge the battery and power the ignition system;
