You cannot see it by just looking at the rubber hub since it's pressed in, but if that prop is as old as the engine there's a good possibility that the rubber is dry rotted just enough to loose some of it's adheasion to the inside and outside walls of the prop, allowing the inside to spin under load. Point is before you pull the motor apart, might be worth your while to just try a different prop.. could be something as simple as that.

Now THAT'D be a homerun!!...
