Notes on Ordering:
1. Find out the size of the prop nut you need.
2. If you need a different prop nut, you need to order it separately.
3. Some engines, i.e. Saito engines, require a bushing that is larger than the nut.
Shiny Finish styles are considered "while supplies last", new style is brushed aluminum.SOLD OUT
