Hi Guys
Ocean Diamond is a 2000 SO 40 with a Yanmar 56 and a Lowrance GPS/Plotter ( HDS7 )among other kit.
I have noted that the Lowrance has the ability to display readings from the engine, such as RPM, consumption, temperature, oil pressure etc. via some kind of connection to the engine
Does anyone have any practical experience in doing this ??

Hello oceandiamond, I once installed a fuel flow function on both engines of a flybridge cruiser. The flow sensors were cut into the fuel lines and I assume they had a sort of paddle wheel which spun at a rate determined by the amount of fuel flowing through the pipe. After travelling around slowly staying out on the boat for a week, I was quite happy with the fuel consumption. I decided to fill the tanks at a convenient fuel wharf even though I didn't think I had to. I explained to the attendant that the tanks would not take much fuel. In fact they were nearly empty. I had neglected to calibrate the fuel flow sensors and I was not seeing the correct fuel flow and hence then the amount left in the tank.  A trap for the unwary. I feel a bit silly telling this story as i should have realised but I nearly did get quite caught out by trusting the reading from uncalibrated flow sensors. The calibration was done from a drop down menu on the chart plotter. Good luck with the interface. Regards, Trevor |

I wish you lots of luck with this. As you say the Lowrance will accept engine parameters but only as NMEA 2000 sentences, the Yanmar engine is not processor controlled as would be the case if it was a common rail engine so your first issue is to capture the analogue outputs for RPM, Temp and oil pressure and convert them to digital then present them to the Lowrance as a NMEA2000 sentence. Good luck with that. |

Thanks guys
Done some more research and it seems that my version of engine does not ave the nemea2000 output needed( more modern engines seem to) so frankly doesn't seem like its worth the effort. Thanks for the input
