GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
Unable to answer why other then increasing pressure will help keep it sealed. Testing at 3 psi and rotating shafts "may" show something. A vacuum test may also
I didnt do vacuum test, only pressure test+rotating the shaft and nothing, no pressure drop, no bubbles..
Do You think to fix it or live with it? I know the prop seal is real pain to replace...
Guess it depends on how much. No one likes putting oil in the water but if your loosing a few ounces all season I would live with and recheck every year. If your loosing more, then might want to go for new seals
