What kind of temperature range should there be on a 2.57 - 1 reduction velvet drive transmission? Its connected to a 135hp Perkins in a 45ft trawler. I had an issue with some slippage my last trip out and a mechanic friend of mine said to check the oil and it was black instead of red and also smelled like it was burnt. Auto-Matic Transmission Fluid. Only had the boat for a year and don't know if or when the oil was changed last. My Perkins guy told me to pump out the oil and replace it with SAE 30 or heavier, which I did and it seems to have solved the problem with the slipping has she hasn't done it since. Just wondering what the temp should be. I have a laser thermometer and after running the boat for a couple hours its showing around 190F. Is that normal or is something going on that I need to address asap?
