I’m with Carl… what the hey is “Contra” rotating.????!!!!… no credibility with me.
Each engine has two props, that turn in opposite directions. It makes for a tremendous bite on the water. I have always called them counter-rotating. Volvo has had this on their outdrives back into at least the 1990’s and I think they got the idea from torpedoes. I am not sure you guys caught this, but the whole engine doesn’t turn to steer; just the lower unit, which will turn further than a whole engine would turn. Some of our antiques did that, didn’t they?
Long live American manufacturing!
