Lower Drive "Milkshake"

[pinecliff]

Would like some info on what would be possible cause for the lower drive oil on my '71 Evinrude "Triumph" 60hp to be taking water. It works OK but when I drained the oil to winterize it I got what looks like a milkshake. Is there an internal gasket or seal that would be the source ? The 2 external screw/plugs were tight, and I see no obvious cracks or external oil leaks.

There are seals where the driveshaft runs through the gearcase, the propshaft, and should be one where the gearcase "cap" is bolted.

The most common cause of water intrusion is the fill/drain plug seals. They are available at any John/Rude dealer and are cheap.
