Aftermarket Rectifier Regulator Assy | Replaces Yamaha 6H2-81960-10

Restore Your Charging System. Protect Your Battery.

If your outboard is suffering from a flat battery, erratic tachometer readings, or blown bulbs, your rectifier regulator is likely the culprit. This high-quality aftermarket assembly is a direct "plug-and-play" replacement for Yamaha OEM part 6H2-81960-10-00. It performs the two most critical electrical tasks for your engine: converting AC power from the stator into DC power to charge your battery and regulating that voltage to prevent damaging overcharging.
