Thanks everyone, tonight I am going to hook the hose up to the boat and turn it on and see if it does it in idle. Not sure if I should try to put it into gear, to see if I can replicate the sound to get a better idea where it is coming from. I did find this article which has a video of a very similar sounding grind, let me know what you guys think. Thank you for everything
