"One of my Yanmar SD20 saildri
"One of my Yanmar SD20 saildrives is leaking oil. It seems to be coming from the upper diaphragm seal, only when it is running.
Q1. Is it correct that the space between upper and lower seal is filled with gear oil?
Q2. the upper seal is fixed with a thin inox band that can not be tightened. Could I replace this seal with the boat in the water?"
