    '85 150 GT Idle Speed, and Screw

    Can anyone tell me what the Idle speed should be on a 1985 Johnson 150 GT? and in case I need to adjust, where is the idle screw?

    A bad day fishing is better than any day of work.....

    Idle Speed (In Gear With Proper Propeller) ............. 600 To 700 RPM
    Full Throttle Operating Range .............................. 4500 To 5500 RPM
    (However, the big boys recommend 5500 to 5800 RPM)
    The Idle Screw is located just above the pivot point on the throttle lever.
    Turn the Idle adjustment screw:
    Clockwise to raise idle speed.
    Counterclockwise to lower idle speed.
