Hi, Im thinking of buying this evinrude 130hp motor. The engine had a new lower unit installed on it a little over a year ago. The lower unit oil had never been drained since it was put on. So, I went to look at the motor today, and drained the lower unit oil. The oils color looked great, but there was a very small amount of fine metal on the magnetic drain, and fill plugs. Is this normal with the break-in of a lower unit? I just want to make sure there wont be any problems because of these metal shavings. Thanks
