Temp Gauge barely moves into Normal

Temp Gauge barely moves into Normal
93 F150 with 4.9 I6
This started with the Temp gauge not moving at all. I tested the temp sending unit wire by grounding it to the body and the gauge moved all the way to Hot. I figured the sending unit was bad so a swapped it for a new one.
Now after driving around for 15 minutes the temperature moves to be just barely in the normal zone and then stops, maybe 1/10 into normal. So at least the gauge is moving!
Coolant levels seem good. Engine seems to be running fine.
I suspect the gauge is supposed to read higher when the engine is at operating temperature. I think its important to have a functional temp gauge. Also, I don't want to be running cold all the time if that is the issue.
Anyone have any suggestions of what to check next?
Thanks and regards

Thanks for the tips and advice. I did replace the thermostat and I now get to between the N and the O. It pretty much stays there regardless of the driving conditions.
I did get it up to the R last weekend by crawling up a logging road in 4x4, so it seems to be reading something! I was beginning to doubt its output! lol!
I guess if I want to know what's really going on I will need aftermarket gauges.
