How much is redundant? Gauges.

[Vezo, Part II]

My MA console is getting ready for rewire. I want my original Johnson hour meter hidden inside console. I’m hoping my compass, mounted top side to port, will not interfere with Garmin 10(84?) xsv face mounted starboard side. That’s a lot of real estate. So, count on Garmin for fuel level and voltmeter? Actually, now that I think about it, I’m upgrading to a Smart tach. Maybe a dumb question.

Not a dumb question at all, going through the same thing as I repower this winter.

I am going to be linking my new Crusader to my Garmin screens (2 840xs units). via NMEA 2000. The Garmin will have RPM, volts, temperature, oil pressure, essentially all the vital info. In between. both screens, I will be putting a tach and two fuel gauges for each tank. I was concerned at first that I needed to have an analog gauge as a backup for everything, but my shop convinced me that I'll be fine. At the very least I want to know my RPMs if NMEA went down. The engine will have an audible oil and temperature alarm.

Hope that helps.

Dealer told me I didn’t need it BUT I’m still a believer in a mechanical water pressure gauge had them hook it up on my gen 1etec had to school the tech a bit as know days everything is electronic

Ditto. I added a water pressure gauge to my ETEC 150HO shortly after purchase.
Also have redundant speedometers. I have GPS on the PerfectPass speed control I added to my ETEC and a pitot tube analog gauge. The analog finally settles in but two slow responding for good watersports control. At speed when there is s difference the GPS is speed over earth with the pitot speed relative to the water. So the difference is the current of the river feeding the lake.

I have a evinrude 115 with an i-con pro gauge ,and a simrad go-7 I networked it all together and engine temp, and tach are the things i look at the most! go figure
