ok just gettin around to this, been a while since I rode in the boat. I keep leakin oil, its grey when i drain it, etc. Water is gettin in, so I got the new prop nut. Is this the seals everyone talks about? This will be the second time to address the issue, the last time, I had the lower swapped out with the new teflon seals. the lower is also stamped TS. What do i need to do to keep this from happening?
