I have never had a problem spraying down my engine bay with water. Do not use a high pressure stream or power washer. Other than that, don't have any worries about it. Modern cars are designed to be "weather proof". think about it, when you drive through a rain storm your motor gets wet, so whats the difference if you spray it with a hose? If you are that worried about it, you can blow it off with some air to help dry it.
