Do I need ICommand Gauge?

First time poster here! Thanks for having me.
just a quick question....i have the ICommand gauges hooked up via NMEA 2000 to a Garmin 740S (ETEC 150HO) Because of that all the info i need is on the 740 (speed, temps, trim etc) Does that mean I can remove the ICommand gauge from the dash? I have a small console on a flats boat and the hole would be great spot for a beverage holder. What do you think?

This assumes that the iCommand is internally terminated AND at the end of the NMEA 2000 bus. Neither is likely.

I have twin ETEC 200HO's hooked directly to my Garmin 4212. Works great. I get all the info my garmin can display including RPM's, fuel managment, trim position, engine hrs, engine alarms, water temp, off hand can't think of anything else at the moment...

Before placing that order, check your current NMEA 2000 network configuration. Even if you insist on removing the iCommand instrument, you near-certainly DO NOT want to add another terminator to the network.

ok, I admit I don't know enough about this stuff. I'll just have Jim at BOE walk me thru it. My luck and I'll blow the whole system up. Thanks again!

I still maintain that you should NOT remove that iCommand instrument. When you posted your previous query, I downloaded the iCommand Users Guide http://www.evinrude.com/BRPHtml/evin...UsersGuide.pdf to confirm my earlier contention that you would be giving up valuable functionality. I suggest you do the same, referring particularly to Pages 88-89. Your Garmin 740S cannot display at least most of these. I believe there are several other data types and functions which use proprietary PGNs, and are thus are unique to the iCommand; but I haven't bothered to chase them down.
Seriously, this is a dumb thing to do to avoid spending nine bucks on a surface-mount cupholder.

Keep in mind that your outboard has an Engine Monitoring system that monitors things like engine temp. no oil/low oil, and the ubiquitous Check Engine. In your case you are notified of problems in these systems through your ICommand gauge. If you remove the gauge and don't install a System Check gauge (which ruins your idea for making space on your console) you run the risk of destroying your engine if you have a failure in any of these systems.
Just sayin.
EDIT:Okay so you wont actually destroy your engine as the EMM will automatically reduce engine speed to 1200 RPM in order to allow you to limp home. But you will be bewildered as to why your engine suddenly shuddered, shook, and then slowed way down, AND you won't know what system is causing the fault.
