Losing Drive Oil

[navcon@cfl.rr.com]

I have a 2005 5.0 Volvo Penta OSi-E, with 130 hours on it. Had standard 100 service done at 90 hours. The engine has a visible drive oil reservoir, which drops about 1/8 of and inch every couple of hours of use. Had the system pressure checked and came back fine. Is it normal to lose a little drive oil in the reservoir after each use.

No it's not normal. It shouldn't leak ANY.

Not sure how the pressure check was done, but the gear lube MUST be drained from the drive, then pressure checked with about 15 psi of air.
I would suspect the gear lube is in the ujoint bellows, did they check the bellows for oil????
