i second that.Hick said:Change your oil. If there is any water in the engine, that is where it woudl be. If there was any more water, you would have hydrolocked the motor.
if there was water in the pistons, you woulda been screwed way before you got home.
drain all the oil out, let it sit there with the plug out for a bit, then fill'er up.
and get a snorkle =) because the intake is the most likely place where you'll get water in your engine from.
