Voltage Regulator Rectifier For Evinrude/Johnson Outboards 4-60 HP - Replaces 173692, 581778, 582304, 583940

About This Product

Is your Evinrude or Johnson outboard not charging the battery properly, or are your lights dimming? A faulty voltage regulator/rectifier is a common issue. This part is an aftermarket replacement designed to fit a wide range of Evinrude and Johnson outboard motors from 4 horsepower up to 60 HP. It's compatible with many common OEM part numbers, including 173692, 581778, 582304, 583940, 777675, 581366, 18-5709, AR104, 72350, and 9-17201. This crucial component does two jobs: it 'regulates' the alternating current (AC) voltage produced by the engine's stator to a safe level for your boat's 12V system, and it 'rectifies' that AC current into direct current (DC) to charge the battery and run your electronics. The unit has 4 cables for connection. Always compare the physical shape, mounting holes, and connector of your old unit to the photos before purchasing to ensure a correct match.
