"As the Captain says you shoul
"As the Captain says you should be fine, normal Cobra's that are raw water cooled should have a 160 t-stat in them, If you have the closed cooling option (heat exchanger) then they can run hotter with a 170 t-stat as they usually have antifreeze in them. You could always pull the t-stat and see if it's a 160, they are stamped on the top. I also have a pair of Cobra's 1989 460's and the starboard engine has always shown 170 on the gauge and the port has always shown 160. I have changed both t-stats over the years for stuck open problems and it didn't change the reading on the gauge so it is most likely in the sender or gauge and I'm ok with that."
