I recently installed a PSS shaft seal in my 1982 Mirage 33 with a Yanmar 3 GMD. This is my first time having the boat in the water with the seal installed. When the boat was first launched I motored for about 15 min went down and checked it and it was really hot. I called the company and was asked a few questions and told to burp it. After that it did help but still felt warmer than I expected. I went out again this time with a infrared temp sensor and found the temperatures ranging between 90 degrees to 105 degrees Fahrenheit on both the carbon stator and the stainless steel rotor. According to PSS anything upto 100 degrees is within safe operating range I'm curious what others have experienced.
