75 hp Mercury Lower Unit

[buckorama01]

Drained oil out of lower unit to service and noticed the oil was creamy like coffee. Not milky white. The drain screw, vent screw, and fill screw were missing O-rings. Could it be just O-rings or do I have a big problem. Shifts good no noises.

Missing seals can certainly allow water intrusion.
