I have a evinrude ficht 150. Model e150fpleea and I had my cousin over to help me get my speedometer working and he found a peice of wood stuck in the little hole in front of motor on the lower unit and we couldn't get it out. So he got a drill bit the same size of hole and went in too deep now there is lower unit oil leaking out. I need to know what needs done and how bad is this, very worried, just bought the boat a week ago. Thanks Aaron
