Not easily. I looked into this when installing a N2K network for stereo and chart plotter. Im forgetting the exact nomenclature but ECM is probably MEFI3 or 4 gen.
Needs to be 5 or later as I recall.
There?s a guy making interface boxes for a couple hundred bucks that bridge the older ECUs data to the N2K network. As usual I can?t recall all the specifics but I have it somewhere in my boat files. Will dig it up and post
