Oil Problem Evinrude 175 Ficht 2003
After my last 2 offshore trolling trips I noticed that I am using A LOT more xd50 oil than normal. I have oil staining on the transom and dark oil leaking out of the Lower unit mid section meeting seam and inside the prop exhaust is coated in oil. The engine runs fine and there is no excessive smoke while running in the water or on the hose.
I have disconnected the return oil line at the oil tank and marked a container at 12 floz and started the engine. The service manual states that you should get about 12 oz in approx. 2 min. I am getting double that amount, 12 oz in 1 min.
I then removed the oil pressure regulator and vacuum tested it. The manual says that it should open at no more than 12 hg mine is opening at about 10hg.
The manual states that there is a internal nozzle in the end of the oil injector housing and if this nozzle is leaking it can cause excessive oil consumption.
This leads me to believe that I have bad oil injector/manifold. (900.00$ part)
Is there anything else that could be causing this problem?
Thank you for any help!
