Mercury 200 EFI, am I hitting a rev limiter?

I I’ll say the experts usually recommend replacing regulators in pairs because if one went bad the other might be damaged too. Have you checked the timing with a timing light. Highly recommend buying a Mercury service manual which will have all the troubleshooting techniques needed for this.
