What pitch prop? High pitch props are often thicker at the hub than a lower pitch.

tyhanks for your reply its a 16x8 as recomended

You most likely will need a special nut like used on the Mc Coy racing engines . A nut with a machined shank ( shoulder nut ) that goes into a enlarged hole in the prop & also threaded in the hex end to take the spinner bolt or screw . Max H.
