OV 17.7 0 168 3 (Power is down and won't idle)

I'm going to guess this has something to do with washing the 900 XP. We went out a couple of weeks ago and got stuck in a mud hole. Tilted to the left and water got in the clutch belt cover and we had to drain the water.

Everything fine for another 3 hours that day.

Had to pressure wash the thing for hours. Tried to make sure I didn't get water in any air openings.

However in just sitting in the garage, went to take it out yesterday. It idles rough and the engine dies when trying to take off frequently.

Once running engine is fine, just down on power. OV 17.7 keeps flashing on the display while running.

I'm assuming water has gotten into something and we're going to start troubleshooting today. Would appreciate any pointers anybody may have.

I'm assuming P0563 or C1063 may tell us what could be wrong?

Thanks.
