What Sense

I have a new-to-me MP 5.7L carbureted engine in my North River jet boat that is a year 2000 build. As I have read from others, finding info on this MP engine setup is rather hard. I'm trying to learn as much as possible about this engine, and would like to know more about the ECM. Is information on the ECM for most any carbureted GM 5.7L from this year likely to be valid for my engine ECM, of course other than specific tuning for my marine application? Does this ECM store any data such as total engine hours? If so, can anyone point me to a reasonably priced reader? Or should I just tow the boat to Autozone and borrow their reader? I'd also like to learn exactly what this ECM does. Any links to that info?
