Yes it's the separate oil tank I just bought the motor and want to get rid of it! So I just mix the oil in the gas and hook up directly to the motor? Nothing to plug or by pass on the motor I've never seen this setup before? Thanks for the info!
I have a 1987 40hp Mariner with AutoBlend and I would like to disable the oil injection and run premix. What do I need to do to this motor to archive this?
