2007 Mercury DFI 1B498790
For several weeks I've been having an alarm sound when I run around 4500rpm. It will limit the power and then alarm goes off and allows the rpm to go back up. If I keep rpm at or around 4000 the alarm will never sound. I've changed TPS, Water Pump, Poppett Valve. Water PSI are around 20 and temp is around 120-122. It never gives me a code on smart gauge. I've taken boat to mercury mechanic and no code come up on the computer. any help?

There should have been a fault recorded if it went into guardian mode and sounded an alarm.

Is it constant alarm like overheat or intermittent beeps?
