The rectifier converts AC output from the engine’s stator into DC current to keep the battery charged while the engine runs — when it fails, the battery drains progressively and the engine may eventually refuse to start. Built to OEM specifications, this unit is a direct-fit replacement for the applicable Johnson and Evinrude outboard applications.\u003c\/p\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson and Evinrude (OMC) outboard engines with AC charging systems\u003c\/li\u003e\n\u003cli\u003eReplaces OMC: 0582058\u003c\/li\u003e\n\u003cli\u003eRefer to Sierra’s current application guide to confirm fitment for your specific engine model and year\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConverts stator AC output to DC for battery charging\u003c\/li\u003e\n\u003cli\u003eBuilt to OEM specifications for reliable charging performance\u003c\/li\u003e\n\u003cli\u003eDirect-fit replacement design\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight for easy installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThis is the sibling to the \u003ca href=\"\/products\/sierra-rectifier-johnson-evinrude-47-5708\"\u003eSierra 47-5708 Rectifier\u003c\/a\u003e — both fit Johnson and Evinrude outboards, but they cover different engine applications. Use the OEM part number (OMC 0582058 for this unit, OMC 0581778 for the 47-5708) to confirm which one matches your engine before ordering. A failing rectifier is one of the most commonly misdiagnosed electrical problems on older OMC outboards — if your battery keeps draining despite being in good condition, test the rectifier before replacing anything else. It’s a low-cost fix that’s easy to overlook. If the rectifier tests good and you’re still not getting a charge, the stator is the next component to investigate.
