A list of Mercruiser engine alarms and fault codes has been widely posted all over the webby-net, so I reformatted it into a 1-page table that I can print and keep on the boat for reference. Maybe some of you will find it useful.
This list is specific to PCM-555 engines (496 MAG and 8.1S), but the basic features are similar for ECM-555 engines (4.3 MPI, 5.0 MPI, 350 MAG MPI, MX 6.2 MPI).
This list is only a summary. For a detailed list, including a full troubleshooting guide, get a copy of Mercruiser Service Manual 33 (for PCM-555 engines) or Service Manual 36 (for ECM-555 engines). You can download a PDF online, or buy a paper copy (e.g., from Amazon). It is an excellent resource.
Let me know if you spot any errors.
