This is what I was looking at. The props run in opposite rotation, cancelling the torque and increasing propulsive efficiency, they say. The props are opposite hand as well.
There is a modest amount of what you might call wobble. I eyeballed it at 1/16-3/32" when spinning, comparing one prop from the other. I didn't pull the props and put a dial indicator on it. so it could be the sum of shaft straightness, hub concentricity/non coaxial error, or prop variation/damage. It looks ok to me for a single prop outboard, but I don't know I/Os or counter rotation in stern drives. The counter rotation drives I am used to are bigger and custom.
There are a few things wrong with the install- like the antifouling paint masking. But I can't afford a new one
