Well If you told us exactly what waa going on we wouldnt be guessing . The prop in the picture is a pressed in hub and is not removable, the part above the prop is for the "Flo-Tork: style hub that fits into the back of the prop
Yeah you need a flo torq hub kit for your engine/prop combo what markings are on the prop and what engine or outdrive you trying to mount it on looks like you have some of the parts already may just need the Delrin sleeve? Just be careful the thrust washer that sits down on th prop shaft is differnt between pressed rubber hubs and the flo torq
