Yamaha Rectifier & Regulator Assembly – SKU 6D3‑81960‑01‑00

Your outboard’s stator cranks out raw AC power; this unit turns it into clean, battery‑friendly DC while keeping voltage right where your electronics like it. Built on a chunky, finned aluminum heat sink, the 6D3 rectifier‑regulator sheds heat fast—even when you’re trolling all day with lights, fish‑finder, and stereo humming.

• Steady 14.2 V output at up to 35 A keeps batteries topped off and EFI systems happy
• Epoxy‑potted electronics lock out saltwater and shock, protecting delicate diodes from corrosion and vibration
• OEM six‑pin harness with weather‑sealed connectors clicks straight into F90, F100, and F115 wire looms—no cutting or splicing
• Integrated mounting ears line up with the factory bracket, so swap‑over takes about ten minutes with basic tools
• Built‑in over‑voltage protection shields gauges, GPS, and LED lighting from sudden spikes

Replace a weak or failed regulator and you’ll notice brighter displays at idle, fewer low‑voltage alarms, and longer battery life on overnight trips. It’s a small part that makes a big difference: consistent power, worry‑free starts, and the confidence to run every accessory without draining the bank of amps. Drop it in, tighten two bolts, and get back to chasing the horizon
