Gotta question - do your engines have an EMM (Engine Management Module
- aka "computer") and if so, how is it cooled?

Yes, Honda BF20 OB, not cooled at all as far as I know.

Yes, Mercruiser 6.2L EFI I/O, ditto.

The EMM knows all and tells all, except when it doesn't. Sensor
reliability appears to be more of an issue than the EMM itself.
