The last two days I've been testing this 20hp Merc out that my brother is considering buying. It's not new, probably early 80's if I had to guess, but this thing has run flawlessly since I've put it on my boat. I used to be a die-hard OMC person, but this motor has really impressed the heck out of me. <br /> <br />I'm gonna have to get the serial number to see what year it is. <br /><br />I told him that I wouldn't hesitate to buy it, it's a damn good motor.
