I'd say halfway submerged is about right. gives you some room to load up the boat. that tracker is floating low imo, probably a 20footer with a large motor. I suspect someone added that wedge to lower the pod, it might not be original to the boat. my pod is 3-4 inches below the waterline at rest, with water in it. I'd still swap props first, who knows, your hub could be slipping. to check, mark the prop on each side of the hub a see if they stay lined up. either way, it's still not a good prop for your setup. and get a working tach, buy one made for johnson/evinrude 2 strokes. they have them on iboats.
