I recently obtained a Johnson brass racing prop made in Oakland, Calif. that will fit a Mercury Super 10 Hurricane. The prop has two small round indents in the rear, the prop is not splined. I heard there is an adapter that will fit into the prop with two pins and is splined to fit the Mercury prop shaft. Is this correct? Are there any of these available? Gary in Michigan
What is the bore of that prop? Any numbers on it? I have one of the spline adapters as well…but looking for a speed prop for my KE7 that is a smooth shaft
