If the prop is that worn due to age, maybe it’s time to look in the gearcase anyway. The clutch dog is made from soft metal and as such is the fastest wearing item in your gearcase. However, the yoke (fingers) that move the dog can wear quickly when the dog is damaged or worn.

Next is the dog and the faces of the forward and rear gears. Since the forward face of the dog wears faster, you can flip it end-to-end to get a few more miles out of it.

All the above wear points may cause a thump-thump-thump, clattering or grinding.

Check the health of the yoke pivot pin. Very rare but possible is breakage or bending of the pin.
