I bought a used 2008 DF140 that had been used in salt water for about 300hrs. The oil was clear when I bought it. I used it once in salt water and several times in fresh water before I noticed that water had gotten into the oil and I had severe corrosion of internal engine parts.
I put a rebuilt powerhead on the engine and inspected everything else thoroughly finding nothing abnormal. When running the freshly-rebuilt engine in the test tank there was excessive oil accumulating in the water but no evidence of water in the oil. When the engine is cranked out of the test tank a small amount of engine oil drips out of the water intake. What did I miss? Where is the oil leaking into the cooling system?
Thanks in advance!
