Propeller mechanic

Hello,
I’m a beginner in UE4 and I would like to make a boat that has a propeller attached that turns when I hold the acceleration key. I made the models and armature of the boat and propeller in Blender and imported it in UE but don’t know how to make it work.
If anyone could help me out or point me in the right direction it would be greatly appreciated.

The easiest way would be using blueprints. You can watch an introductory video tutorials about blueprints.
