Here's the deal, I had, had my boat to the mechanic to do a lower shift cable replacement. Allot of other things went on during that so to make a long story short I took the boat out and my lower went out. The mechanic broke the skeg backing it into the garage and had a new one welded on so when it went out I thought the welder burned a seal and that is how the water got in. I called the mechanic and he said it wasn't his responsibility on that but he would pressure test it and see were the water got in. I knew he took the entire uppper and lower out in one piece so something kept eating at me and I decided to take the upper off and when I did there were two big o rings there. The mechanic evidently didn't see the old o ring on there and put the new one on and tightened the upper up. With the two o rings smashed together would that allow water to get in the upper drive there for mixing with the lower? As soon as I loosened the six bolts holding the upper on water started coming out and I knew there the problem was. I got it off and the boot had water in it. I'm going to see this mechanic tomorrow and I just want to make sure my thinking is right. Thanks, guys, Chris
