So, this is gonna be a dumb question. Are the new duo prop prop shaft splines twisted
From the factory? 21766684 DPS-B

Thanks. They are just twisted so perfect looks machined. Even the splines in the prop hub were twisted without distorting. Props slid right off. Thought maybe they had changed something

Then let me back up, never seen a twist on the splines, and since they look so perfect I might be wrong (would not b the first time). Hey bruceb58 what say you?

Thanks guys. After more research it appears the the DPS-B use what they call helical or spiral splines for torque distribution. Scared the heck out of me when I pulled the props off.

My 2013 is the same. Definitely strange the first time you see it.

well, you will. First i felt bad for the guy...then I thought "sucks to be him" I am gonna make some money on this one... Then I looked at the props and while dinged up they werent that bad...and I said to myself " better not make yourself look like a jack***" better research...and if you dont learn something new each day....
