[This article was originally posted to a very old thread in the archives on a different topic. It has been separated into its own thread--jimh]

I have an older 1980 diesel engine that I want to connect into a [NMEA-2000 backbone] I currently have installed. Obviously my engine is not new or wired for electronic output of RPM, Oil Pressure, Engine Temperature, etc. What are my options for [an interface] for an older analog output engine? I do have a basic harness that brings information to the current set of analog gauges at my helm. Are there sensors that will allow me to pull this information into my NMEA-2000 system and display it on [Evinrude I-Command Classic gauges]?

Check the MARETRON website for NMEA-2000 devices which can be connected to conventional analogue sensors on an engine. Diesel engines are not generally used in small boats, so the general topic of converting older diesel engines to use NMEA-2000 instrumentation is probably outside of the area of interest here. Evinrude I-Command instruments are designed specifically to be used with Evinrude E-TEC outboard engines, so I would not anticipate they will be able to display parameters that might be important on a diesel engine, such as oil pressure, fuel pressure, and other diesel engine parameters. You would be better to use a NMEA-2000 display which was intended for use with diesel engines.

I suggest you move your inquiry to

Thanks for your help. I'll check with Maretron and see what they might have that could help me with engine monitoring.

for information on the MARETRON product that seems most appropriate.
