X-Star won't start, and perfect pass dash won't display anything. What could this be?

So I was out for a wakesurf today. My buddy was driving and when he took off, the perfect pass normally kicks in and sets my speed for about 11mph. However, this time I noticed he was going well over 11mph. At first I thought he forgot to turn on the perfect pass, but he basically yelled back to me stating that the Perfect Pass had shut itself off. So I basically told him to cut the throttle. I got in the boat, and he had already turned the boat off. At that point, we weren't able to start the boat again. And nothing on the dash was working, and the perfect pass dash wasn't displaying anything. I thought at first that maybe the battery was dead, but all the pumps and lights in the boat were working perfectly fine. So we basically drifted to shore and got someone to give us a pull back to my dock. The problem remains! It still won't start.

Anyone have any idea what this could be? Maybe something electrical? There was a little bit of water in the bottom of the boat today because of unrelated things I was trying to fix in the boat. Could that have shorted something out?
