Have an 2001 opti 150. First time out today. Here is my problem. When at idle the temp would rise until it went into safe mode. If I let it cool down, and don’t idle very long, and then get on plane all the way to WOT the temp drops like a rock to 90 – 100 degrees. And stays there as long as I’m on plane. I think its the thermostats, because in my repair manual it states “Thermostats (2) 143 degrees F, If stuck closed, engine will overheat at idle.” I don’t understand this, why the over heat just at idle? And would like to know if anyone has had the same problem. Thanks!
