I have a 2001 evinrude 200 hp, efi. My prob;em is that every time I run the boat I get what appears to be straight oil dripping down the tail shaft. I have pulled thye cowl several times ( and taken to shop) to find no noted leaks anywhere, except that the air box seems to have a puddle of oil in it. The shop can give no reason why the motor would drip oil back into the air box and cause the oil streaking that I am getting. Is there a cause of this other than gravity? When I bought the boat it showed no signs of oil streaking, and I did'nt get the streaking until I had to have the computer changed. But I can find no evidence of any oil leaks other thatn what is building up in the air box.<br /><br /> Any one got any ideas? Is this normal?<br /><br /><br />Thanks for any help<br /><br />Mark
