9.8 Merc lower seals

[pontoon chief]

Just completely redid all seals in the lower end of a late 70's early 80's 9.8.<br />Within several weeks the lower unit started pushing oil and water mixed UGH up and out the seams and exaust ports etc.Checked the lower end and the oil was mixed with water (milky) and low.<br />Removed lower end and all areas within the housing was filled with gunk and slime.Cleaned unit up and pressure tested the lower unit.No visable leaks noted and no air leaks that I could find.<br />Any ideas?

Probable the driveshaft is damaged on the seal surface thats the most common problem
