My wife and I live on a 1978 44' Gulf Star trawler with two Perkins 120's in San Diego Harbor. I try to run the engines 3 or 4 times each month for 30 - 40 minutes. Each time I fire up the engines they blow lots of smoke -- which doesn't worry me -- but a good deal of brown stuff which I suspect is rust -- into the water for the first few minutes. This I do worry about. Is this normal? Should I be doing this a different way? Any suggestions or information appreciated.
