A slipping prop hub will act like a car with a worn clutch, RPM will climb excessively when power is applied but the prop isn’t really spinning due to the worn rubber hub in the prop.
A worn clutch dog will be more of a violent jump when power is applied, almost as if you hit something. Perhaps your shift linkage is loose or misadjusted causing the problem, but misadjustments like this usually cause clutch dog wear as well.
I sure hope the problem is the prop hub!
