Yeah, there seems to be a lot of different temps... with gauge inaccuracies and water temps, air temps, boat usage i guess. Seems as long as you got a temp that it stays at, you're good. I'd be worried at 190. Mine stays rock solid at 160 once it has warmed up unless I turn the boat off right after a barefoot run.
From what i've read, indmar puts 160 thermostats in... but that doesn't mean the engine will run at 160. It can and will run warmer... should not run cooler unless just warming up. Raw water cooled runs cooler because there is no pressure in the system... so boiling point is right around 212 which you don't want to happen. Also, salt and other minerals start leaching out of the water around 180-190 and can form deposits in the cooling system.
however with new reg's coming with cat's and stuff... and closed cooling... running temps will be increased. Cooler temps make the engine run less efficiently.2010 LSV

Glad to see that 180 is the norm. I was worried the impeller might not be working correctly. Is there any way to test the impeller?

You can't really test it without running the engine/cooling system. Sounds like yours is working. You should conduct an annual visual inspection of it and change I think every 2 years or 100 hours or something like that. You are looking for cracked rubber or missing veins. Most change it out after a year or two and save the backup one for a spare if it looks ok. Keep it in a sealed plastic bag.

I installed a new impeller this year, she is still running at 180. The weather and water temps have been very cold here this year, no change.
