Designing a boat propeller in OnShape

I want to design a boat propeller using OnShape. I have a physical 9.25 inch propeller from an outboard to use as a guide for measurements. I want to start design from the center and move outward.The center of the prop has hub with beveled splines - 10 splines total. The outside of the splined hub is 20.5 mm, the inside of the hub is 12.5 mm. The spline height is 1.5 mm and the spline width is 1.5 mm on the tip extending to 2 mm in the valley. Is there a repeatable way to model the splined hub? Rotate function?

The above is a propeller example my coworker Phillip Thomas made. You can follow the methodology that he used by making a couple profiles and lofting them together then just using a circular pattern to get multiple of them.
If you have examples of what you want your "splined hub" to look like, we can give more specific help.

The hub in this picture has more splines than mine.
Thanks,

I'm a total beginner with no training and just starting to self teach myself in CAD but I saw a youtube post that might help you in this scenario.
Good luck.
