How do I know if it is compatible?

We recommend checking your existing part's number against the OEM Cross Reference list above. If your original part number matches any of those listed, this unit is a guaranteed fit for your Mercury engine.

What symptoms indicate I need a new regulator?

Common signs include a battery that will not charge, dimming or flickering lights, or the battery "boiling" over due to over-voltage. Replacing a faulty regulator prevents damage to your ignition system and battery.
