I recently replaced my impeller and hooked up the water lines backwards, so my boat overheated while running at about 30mph. I switched them back and the boat wouldnt turn over. So I pulled the boat and took it to the shop. The guy called and said the oil level was about 3 quarts too high, so they drained the oil and had about 3 quarts of water in the oil pan. He didn't really know how it got there. His though was that water got in the intake, but I don't see how that would have happened. Everything is fine with the boat now. He replaced the spark plugs, oil and filter and it runs fine now.
Has this happened to anyone else? Does anyone know how the water got in there?
