Hello everyone. I am new to this forum and have a question. I have a Mercury 200 EFI Pro Max Ser# OG367943 and I'm having issues with the engine killing when I run above 5500RPM. Below that it runs great and will do so all day until I get over 5500, then it just kills like someone pulls the kill switch. I have about 14.5 volts when running and changed the voltage regulators because the plugs were burnt looking but that didn't fix the issue. Any Ideas? Thanks for any help in advance.
