I have a yr2000 Johnson 150 ocean pro. Burning lots of oil (1 gal oil to 8gal fuel). Do I have a bad VRO pump? I have checked the fuel line and found no restrictions. Lots of blue smoke but runs and idles great. Any help would be appreciated..
Well you are off to a good start by checking the fuel line...is there any sign of oil leaking into the boat somewhere?<br /><br />As you already suspect..there is something wrong with your VRO. Either change it out...discontinue with oil injection...or have a Tech test the pump...sounds like the fuel side is a little weak.<br /><br />TMD
An air leak in the fuel system is the most common culprit for making a VRO pump too much oil. Insert a piece of clear fuel line at the inlet fitting and run the motor at all speeds while looking for bubbles in the line. A vacuum gauge "teed" into the clear line should show a restriction of less than 4", 2.5 is ideal.
