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 :confused:

This really isn't abnormal...I think it shows up in the front when the engine is trimmed up or out and I have personally seen this using one particular type of oil being worse than others.<br />Are you having to run at idle for a distance inside of "no-wake" bouys or something, maybe not alot of WOT time???<br />You may want to take a peak and make sure all oil lines are connected properly...

We most certantly have @ 20 min. no wake zone before we get to the launch, that sounds like it could be my problem! Thanks

squeeze the oil return hose between the oil injector and the pressure regulator(red&white thingy in oil return hose)if oil leaks at the injecter there is a fix-new oring only avaiable from dealers thur bombardier no part number avaiable have your dealer call tech support to get an oring <br />if not the problem may be just oil leaking out of throttle shafts
