I have buddy needing a lower S/N og283141. The sop is telling him it a counter rotation and that seemed odd to me especially after looking at his prop compared to mine, they look the same and mine is standard. We are in Missouri so i dont understand why his old rig would have a counter rotater on a Cobra Bass Boat And any leads on a lower would be great too, he just is worried about ordering the wrong thing. Am i missing something obvious?
