Engine problems began approximately 5 mi south of los alamitos, which was about 10 mins into the flight. After landing it was discovered that the fuel was contaminated with water. Although both wing tanks had been drained and inspected prior to flight, the main sump under the cowling had not been sufficiently drained enough to eliminate all the water.
