    Trim Tab Adjustment

    On a 1981 75 hp Evinrude at full throttle the steering wants to constantly pull to the left. Which way should I adjust the trim tab (left or right) to correct this? I am assuming to the right but I want to make sure, and I am assuming that a slight adjustment would make a bid difference.
