My little brother is really not that boat savey. Well he is, but when booze are involved he tosses all his boat knowledge out the window. The lake I live on is super low right now, as are all lakes in MN. So the other day he takes out my X-star, after he calls me and says, "Hey man, I think I put a ding in the prop." I go right to the typical lecture about not being an idiot, and paying attention.
So yeah it had nothing to with the prop, check this crap out. In fact the prop is just fine. I have not Idea how in the hell he did this.
