Title: wrong temperature
Review: I bought two of these "143 degree thermostats" for my twin engine boat. The only problem is they don't open until much, much hotter. I tested them in a pot of hot water after my engines moved into the red on the temp gauges. The thermometer I used for testing maxed out at 190 degrees, and the thermostat didn't open until well after that. I don't know the exact temp, but it had to be over 200 degrees since there were gas bubbles forming on the thermostats in the water before they opened.
