Hi,
I have a Sea ray 270 Sundancer with a Mercruiser 7,4 MPI (MEFI-3) modelyear: 2000
I just scanned my ECM and found this error code. I cleared the code and ran the boat and the alarm goes off again.
My engine alarm goes off between a few seconds and a few minutes of going on plane above 3000 RPM. This is a new problem that just came up this season. The engine runs well when the alarm is off. The alarm does not go off if I reduce RPM to idle, but will go away if I shut off and restart the engine. But it will come on again when i get back on plane.
I've changed both knock sensors and mounted new connections on the knock sensors.
I've also tested the wire from the ECU down to the connector with a multimeter and it beeps, so it seems to get connection all the way.
I've sprayed all the connections I can se with CRC 5-56 just to be sure nothing has rust on it.
Does any of you have had the same problem and how the h*ll did you fix it??
