I'm thinking of buying a mid 70's Mercury inline 6 cylinder 150 hp that has no controls. I have a 80's Mariner on my ebko with electric tilt/trim it is a V-6 150 hp. Will my controls work on this unit? And do you think $500 is a good price for the motor without controls? "He said it ran before he took it off the other boat with a bad transom" I'm going to take pictures of my motor setup, controls, gas lines, and oil line setups. And then compare them to the other motor. Please chime in with the advice. I know there are a lot out there that have or know how to either make this work, or to save my money.
