I don't know what I said that made to mods upset - more time to spend with the family!
Massive - I have had to oil issues on my boat:
1. Trim Cylinder on the right is seeping oil out of the o-ring where it goes into the rear cylinder port - bad design, and I haven't been able to find an oversize o-ring that stops the leak. I did buy a virtually new used ram cylinder from ebay, but haven't had time to install it yet.
2. Drive oil had water in it - compression / vacuum test was stable - the heli-coil on the top of the drive dip-stick had a the end lifted, I think it allowed a bit of water into the drive when it wasn't tight enough. hammered the heli-coil end down, new o-ring, and no issues since.
