What is not so??? I fail to see the point.
OK, I see where you're coming from. You're going on the assumption that a 4 stroke can never equal the torque of a 2 stroke when both are optimised for a particular rev. I read what you said as meaning that if both a 4 stroke and a 2 stroke produced the same torque at the same revs then the 2 stroke could swing a bigger prop.
