View Full Version : Engine Rotation Confusion

06-25-2012, 01:02 PM
I have a question around engine rotation and I've been unable to find a post that fully answers my question. I have a 1991 PS190, 351W that has standard rotation(LH rotation). Does this mean I need a Clockwise Starter (opposite the rotation) or would it be Counter-Clockwise(same direction as engine). I understand that it has to turn opposite of engine rotation, but is that taken into consideration when they label the direction of the starter? I went ahead and ordered CW Starter but am starting to second guess myself. Can anyone give me some clarification on this. Im switching to the permanent magnet (new) starter due to the fact that it would cost just as much to rebuild the old one.

LH engine = CW starter
RH engine = CCW starter

Thank you very much. That's is what I assumed
