Awesome design! I have printed these parts and they came out beautiful! I also have a hull on the way for this unit as well and all the parts (5mm shaft, bearings, motor, esc, etc.)

Is there any way to change the design so that the Inlet_Water_Jet_Drive would accept an 11mm wide outer diameter, by 4mm deep thick, 5mm inner diameter ball bearing where the shaft enters? The stator_cone file would also want the same ball bearing to accept as well when the shaft leaves through the impeller into the stator. This would improve performance, efficiency, and alignment greatlyl at these high rpms.

This is the bearing I'm referring to: https://www.amazon.com/gp/product/B00KHVK6WY/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1

I can't wait to get this built after watching your videos of the boat. Without the editable files, I can drill the holes, but not nearly as precise as I can print them.

Thanks sooo much for posting a great design.

I am designing, and will post in the next few weeks, a sweet hull that can be 3D printed that this water jet drive can bolt right up too for everyone here.
