Engine Temp Gauge on 5.0 Volvo

My engine isn't overheating or anything, but the temp gauge doesn't register anything, until it does. Is this common? Yesterday it started out dead and after 45 minutes or so I noticed it was working. I just bought this boat and knew this gauge had an issue. A few weeks ago on the test drive with the previous owner it did the opposite. It started out working and then stopped after we were out for a while. Any ideas what could be going on?
Not working.

With no overheating alarms I’m guessing it’s a faria gauge getting tired. Which is possibly a good thing right?
Loosen then re tighten your gauge connections , and the same with the engine temp sensor.
You would have to multi meter or ground the gauge to check for sweep during the failure.
Faria does a repair service but that gauge may be findable with a part number search.

Tap on the guage glass and see if it comes back to life. It's easy to diag once you find the sensor.
