Having an issue with my Bravo XR leaking oil and also getting some water in the oil of my drive only when its under power. I had it pressure and vacuum tested and holds pressure fine. After running it yesterday I can see some oil residue on both sides of the upper where the drive bolts to the bell housing. Assuming it has to be one of the o-rings not sealing around the shift cable to reserviour line but wouldn't that make the pressure test fail?
