What a difference a day makes! Put a sample of the liquid and gunk from the radiator into a mason jar and went to the best diesel people around, walked into his shop and said I need a oil analysis on this, he took it from me, leaned back in his chair, smiled and asked me why and I proceeded to tell him, he interrupted me and said, "there's no oil in that" I asked him how he could tell and he said "it's it's a glass container and there is no oil on the glass, he said all it is is coolant that hadn't been changed in a long time. Asked where the boat came from I told him Washington and also Alaska. He went on to tell me that up there they put all kinds if fluid in the coolant, just flush the heat exchanger out several times and everything gonna be alright. A good example of plain ol common sense, an in the field oil analysing test! Tom Petty said it best "most things we worry about don't happen anyway!" Gonna sleep good tonite! Thanks to all who participated in helping me out, it's appreciated.
