How would it rust from the inside if it was full of gear oil?I agree! Those Zeus pods are like a time bomb. When it goes off, and it will, it will cost thousands to fix. I replaced one entire pod. It rusted out from the inside! $20k to replace. Then the power steering seals blew on the other motor - $4,500. I couldn't wait to sell it, which I did just a few weeks ago. They don't make them anymore for a reason and Cummins has distanced themselves for Mercury. Never again!
