I had my boated winterized and my 2003 bravo 3 pressure tested serviced and reinstalled. when I unwrapped my boat I found all of the drive oil leaked out and the drive was in a puddle of oil. Looking at the back of the drive the rear anode is soaked in oil. The marina that did the work said they would look at it and repair any damage that they caused, but if it is something I did I would have to pay for it. All I did was trailer my boat 6 miles to my house. I need to know what could they have done wrong for this to happen? This was the first time I used this marina.
