I was out on the river and sucked up a rock and some weeds. I pulled over and pulled out the weeds and got the rock out through the hand hole. It looks like no major damage was done ( no chunks out of the impeller). It has a few tiny nicks that look like can be cleaned up with a file. The boat has no power after 3000 RPMs. Its acting like sometjing else is still in it, but I dont see anything. Is it possible there is something else behind the impeller? What else should i be looking for. Thanks guys.
