Remove the prop and draw a line with a Sharpie across the back side of the prop. Remount the prop and go for a ride. Once it slips remove the prop and see if the line you drew is still straight across. If it isn’t your prop hub is slipping.

Absolutely agree with johnny on this.  However, there is a simpler way.  No need to remove the prop to mark it.  Simply mark the prop NUT and an aligning mark on the prop.  If the hub spins, the hub, shaft and nut all turn at the same time, and the marks will no longer align.  Nice part is, you can check by tilting the motor out of the water and looking.  No off and on with the prop.
