I have a 1997 Wellcraft with a 5.7 volvo penta outdrive cobra sx.The problem I have is when I turn,it makes a grinding kinda thumping sound more when I turn it to the left.I had the outdrive taken off and they said the u-joints were fine and gimble was changed resently.I bought the boat 7 months ago and I just got back from a 2 week vac. on the lake and drove it every day pulling tubes and riding.I did like 5 hours a day and I was waiting for something to break but it still runs great.I put a new prop on while I was up there too .Any help would be great!!This site has helped me in the past so I hope for some good help again thanks in advance for any help!!
