The water temp and oil pressure gauges are off. Autometer marine's are 100 to 250 water temp, and 0 to 100 oil pressure. Gaffrig and Livorsi are 100 to 240 water temp and 0 to 80 oil pressure. I've installed them both and no matter what Autometer says they are both off. You need the Autometer sending units for them to read properly. I personally like the Autometer gauge, I think the 2 1/16 full sweep with the round rings are better looking then the step rings with 90 deg sweep on the other two, but you will need new sending units with those two particular gauges. The volt, trim, fuel, tach, speedo, gps speedo and probably all the other gauges are fine. Give it a try back to back with one of the other gauges Rex and you will see the temp and pressure differences. Maybe no-one has ever brought it to Autometer's attention??

The looks of Auto meter marine gauges are by far sweeter looking then the others....just my opinion


.

I wouldn't put them in my kids go cart ether, way to nice of gauges for that Plus there still not that cheap in price.
Heck...if there good enough for Herbie the lovebug, there good enough for me. NASCAR use um.
