Hello all, I'm new here and wish I didn't have to post this. I had a rock stuck in between my impeller prop, good news is I got it out.I tried to remove the impeller grate bolts but, they just kept spinning, is this common? I ended up using an awning rod to knock it loose. I looked at the rock and it has a little gouge on the one side and something black on the other. Should I take it and try it on the water or just take it to the shop? What could've been damaged by this? I also have OTAS failure on my screen. How do I attach a picture? Any and all help is greatly appreciated. Thanks
