The water beads could be from a leaking head cover gasket. There is a separate gasket which goes under that cover and it could be leaking slightly around the plug. You could re-tighten all those bolts on that cover and see if that fixes it. What makes you think there is water in the gas...did you take a fuel sample from the tank, or do you have water in the cylinders? Water in the cylinders may not be from the fuel.
