ARCO VR004 Yamaha 75-115HP Voltage Regulator

The ARCO VR004 voltage regulator is specified for several Yamaha four-stroke outboard families from the 1990s and early 2000s. The supplier identifies 75 and 80HP applications from 1997-2000, 90HP applications from 1994-1999, and selected 90 and 115HP engines extending into the early 2000s. Because Yamaha revised charging systems over time, the original regulator number should be checked rather than relying on horsepower alone. The VR004 is intended to preserve the factory charging-system layout.

Yamaha 6H0-81960-00-00 is the primary OEM cross-reference. CDI Electronics 197-0002 is also listed as an aftermarket interchange number. Those references make it easier to identify the correct regulator when the current part is not Yamaha-branded. Compare the connector, mounting, and wire routing with the removed unit before installation.

Inspect the stator leads, battery connections, grounds, and charging-system plugs for corrosion or heat damage while the regulator is accessible. A damaged terminal can create charging symptoms even when the regulator is functional, so surrounding wiring should be corrected at the same time. ARCO lists 12 months of materials-and-workmanship warranty coverage for leisure use and 90 days for commercial or racing applications. Confirm charging performance with the applicable Yamaha test procedure after installation.
