X2 I'd like to know about this as well

 

I have a 115HO networked to a Garmin 740s. It also has the iCommand gauges which also are NMEA 2000 based.
There is a bit a extra electronics, like the engine has a fuel memory module, fuel tank sending unit, etc depending on your priorities. I keep 4 little data boxes on my gap screen including speed, water temp, depth and mpg. MPG is the only one that gets engine info. I have to push several menu choices to get to the screen that has engine info - fuel flow gph, rpm, engine temperature, etc. I generally get this info from iCommand only. I set it for engine temp, rpm, water pressure which displays all the time, and trim pops up when I hit the trim switch.
So, unless mpg is really important to you, iCommand may be best for real world use. Otherwise you will spend all day punching on the gps to switch views around.

 

It is very dependent on which FF/chart plotter unit you have. Humminbirds have 3 preset view buttons down to the 700 series. You will need NMEA2K backbone, ff/ chart plotter, and the HB NMEA interface. You could set one preset view button to engine data. Also, on HB's you can hide views so you do not have to rotate through views you do not use.

HDS 8 and 10 have soft keys that can be used in a similar way as the HB prest view buttons. The HDS 5 and 7 do not have this feature.

 

Does NMEA work with Yamahas?

 

still not sure if I want to do icommand or garmin :-/

 

Go with I command and rethink the 40hp , unless you fish Alone a lot.
