Just did my first engine oil change on my ’12 500 HO. When I removed drain plug from oil tank, I got about a 1/2 cup of water before oil started flowing out. The oil level was a bit high before I started change, but not that bad. Engine ran fine before, with no unusual sounds or exhaust smoke. After re-reading manual, I found section on oil change that mentions possible water in oil tank from cold weather use. I use mine a lot during the winter hunting season, so I am guessing that is why the water was in the tank. I have 55 hours and 160 miles on the bike. I am the 2nd owner, so I am assuming the oil has been changed at least once before I got it.

Was this a quirk, or should I expect to get water in the oil tank every winter?
