    Lower Unit Trim Tabs

    Is there a difference between CW and CCW trim tabs?
    The ones behind the prop under the cavitation plate.
    Have twin CW lowers and found a CCW one I am installing.
    Read in the manual that the trim tabs are NOT interchangeable???

    Yes the curvature is on opposite sides due to the co-ro prop. Because you have both lower as standard rotation you should use the same tab in each for the cooling water pickup in the tab.

    Guess you missed this: found a CCW one I am installing.
    So, I do need different ones.

    No I saw that. My intent was to write use CW on both lowers. My reference to rotation is standard / right hand rotation or counter rotation / left hand, as reference to clock movements has not been part of usual Evinrude nomenclature.

    CCW does have a different part number than std rotation. CCW # 0338743 Std # 0338742 so it appears there is a difference as Bighare said.
