Sometimes at idle the guage would climb to 160 and then drop after accelerating. I assume everything is working as it should.

I may still relocate that sensor this spring and see where that takes me. I like to have accurate temp reading while using the boat. Don't want to overheat that LT-1!
You know your engine has two thermostats, right? If the second one is sticking open, it will never get warm.
