I picked up a new to me boat middle of last summer with a 2014 200 Etec HO. When I winterized it the LU lube was milky. I pressure tested the lower and it held 10lbs for well over a minute. I ran some lube through the top hole until it came out clean and then filled it up with fresh lube and replaced both gaskets which looked a little sketchy.
Since the pressure test seemed good and I replaced the gaskets I'm assuming that the gaskets were the issue. My plan is to run it for a few trips in the spring and drain it to see how it looks.
Am I missing anything?
