Anybody know the Merc oil thermostat temp spec used with the 575sci oil cooler? I just changed the water stat and know that it is 140. Is there somewhere that Merc gives this spec? If anyone has a pic and description also of where the oil stat is located it would help. If I knew where to locate it maybe I could remove it and take a look.

Thanks
Dave

Well if no one knows, does anyone know someone that might know. Just point me in the right direction.

Here's a picture of where it's located:

I would bet it's going to be around 210*.

That's where my HP500's were.

( just hot enough to boil off condensation)

here you go, opening temp is 140
