Thanks, JClark. I suspected marine age was a contributor. These turbos were refurbished in 2008 and have 1800 hrs of salt use. Some of the other forums think vertical drop to waterline is the contributing factor, but I don't think so. My turbo guy thinks they look normal for that amount of time and hrs.
