water temp gauge

When some gauges are not working they return to their neutral position which I'm guessing is 150 in your case.

I use to fly a 1962 Piper Cherokee. Both tanks were reading 1/2 full. I ran out of fuel in flight. I was at 9,000 feet and a small airport was close by so it was not a problem. When the gauges were checked out the ground wire had fallen off so they returned to their neutral position and showed 1/2 full.

 

Iam no pilot but been around planes and heard more than once you don't go by a gauge-you manually check before flight.

 

Lol....Yup. I actually did check but only one wing. My fuel selector was on the other wing and that's the one the ground fell off. I did go through the emergency procedure and pulled carb heat, switched tanks, established max glide and looked for a place to land. The engine did fire back up but I was too wigged out and landed. Mechanic found the problem in 5 minutes. Same procedure used to test a trucks fuel tank sensor.

 

so you did your pretrip like a lot of truck drivers, huh? present co included.
