spinner adapter nut for moki 1.8?
Here is a pic of a Zinger 20x8 prop hub (top) and a Zinger 22x6 prop hub (bottom).
The thickness of the prop hub of the Zinger 20x8 shown in the picture is a little more than 11/16" (18mm).
The thickness of the prop hub of the Zinger 22x6 shown in the picture is about 5/8" (16mm). With the Zinger 22x6 almost 1/4" of thread will remain for the Higley spinner nut (about 8 threads or 8 turns).
