Re: Which propeller
Your question reads a little odd...not sure what you're asking....counter rotating props swing left(counterclockwise)....but if you're asking how to tell a c.r. prop, just rotate the prop slowly with your hand and imagine it going through, say soft butter, and you'll be able to tell...the blades have to turn in whichever direction will take 'butter' from in front and put it behind the blade....counter rotating lower units will have an 'L' stamped into the 'spine' above the trim tab anode as you look down on it....
