Hit a log

I hit a log on the lake today and bent the prop. I took the boat to the local marine, and he said he can repair the prop. I was talking to a buddy of mine and he said I may have bent the drive shaft . It does not look bent and the owner of the marine did not say it was bent. I'm wondering is it hard to bend the drive shaft, or if there is a way I could tell if I bent it. There was a small vibration after I hit the log and I went straight to the dock and checked the boat. Only two ears on the prop tip were bent. Hopefully it's only the prop I can't tell. I,m leaving the 15th for Alabama to wakeboard and want to make sure my boat will be ok. Any help would be great.
