I have a 96 Hunter 376 with a Yanmar 3JH2E that has no gauges, just idiot lights for oil pressure and water temp. And because we only use the motor occasionally (in and out of dock) it would be prudent to know the thing is running within spec. So I found and interface that will work with my NMEA2000 network and will provide information to my chart plotter. That's all fairly simple stuff, but the question is, is there another oil pressure port in the motor or do I need to remove the factory sending unit and replace with a new sending unit. I can't seem to find info on this anywhere.
Thanks in advance for any insight.
