Chris, Check the shear pin on the prop. Also check the adjustment on the shift linkage.

If the shear pin is okay... then it would sound as if the prop hub (a rubber spacing between the prop and the shaft) might be shot. It is almost impossible to tell by visual inspection - but if it is split, the prop will slip on the shaft when you give it gas - though seem snug when you check it manually....
