I think I have tracked down the issue with my 1995 Merc 200 EFI after I noticed I have used a gallon of 2 cycle oil in less than a few hours of running.Could the oil injection pump be stuck in the open position? My thought for testing is to simply premix a tank of gas and try it out.
Will it cause any damage to any of the systems if I simply plug the oil injection supply line from the tank to cut off the oil supply during the test on the lake?
