Hi. Yeah. Think I can.
So you won’t get anything more than the basic screen without it running. All becomes active when she’s running.
Very briefly and basically, the main screen shows three sections. Speed, rpm and fuel. Should you click on each one of those readings, it will go to a more detailed sub menu screen in relation to each. Then further sub menus after that even.
If you press the rpm read out…you will get basic pressures and temps on the screen. You can (and should) then press the top of the screen where it has an add or plus sign. That will allow you to select and display a host of further details and readouts to show water pressure, oil pressure and a fair few other things too.
I could go on for a while about the set up and things…but I’ll leave you with just the basics for now. Some readouts require the engine to have the required sensors and/or digital module unit to suit. You should also take the time to create a user account and log in too. This means you can also see exact descriptive detail on screen, from any faults picked up, should you have any. All the best and any issues, get in touch, by all means. I have this on the mercruiser mpi and also more relevant (to you), on my mercury 115 outboard. Basically the same engine you have there. Just different mapping between them, on the 75-115 models. Clocked up over 1400 hours so far on her.
