I have a 1993 Mercury XRi EFI 175hp Black Max. Voltage at battery with engine at Idle is around 13.5 volts. At roughly 1500 RPM's voltage at battery climbs to over 16 volts. I assume this is too much. This particular motor has 2 regulators. Is it worth just changing the one or should I change both or could there be some other problem. If so, is there a check I can do myself. Have read many different things regarding this issue. Some that suggest there could be a problem with the stator.
Thanks for the info>>>>>
