Bud, you make a good point, and I guess everything is a gamble, but other than the electrical system, or maybe I should say, "electronics", I personally would chance flushing the engine and running gear, based on the experience that I had with the lawn and garden equipment. This stuff was in a flash flood, so you know how much silt and contaminants were in that water. I purchased 6hp shredder myself and wore it out without any problems from the flood. Other employees purchased tractors, mowers, etc. without problems. As I said, I will give you the point, and will admit that today's vehicles have more that can suffer damage than in older days, but still, you constantly see warnings about checking a vehicle for signs of flood damage, so obviously someone is cleaning them up and selling them.
