I am in the market for a 28CC with Tower and have noticed that most of those available have the Cummins 4BTA250 engines. Most are in the 2001 vintage. Given past comments on this board, just how bad is that engine combination? Noise appears to be a common complaint. I'm all the way over in Hawaii and am depending on quite of bit of internet research and photos to narrow the search down before a site visit. Any help would be nice.
