Hi; Have a propeller that matches up to the dimensions listed in the identification section of this website for a Curtiss engine, except for the hub thickness. Center bore, bolt size and bolt circle all look good. but the hub thickness is about 5 3/4" not 4". Can anyone in the community shed any light on this? Thanks
