It is indeed a 25mm shaft. That I know. And I can find a prop with 1 1/8 inch bore that I can fit a bore reducer bushing to go from 1 1/8 inch to 25mm. The problem is also finding the prop nuts. Any resources? My local (Tampa Bay) prop shops won't discuss this option. Saying the bushing is of questionable durability and they have no clue where to get the prop nuts and anodes for my 25mm shaft.
