Building a Kort Schottel Drive Unit
I started to build a "Rhine Tug" it's a pusher called the Egrete, from a set of plans that I bought. Selected it because it had some neat challenges. 1st was making the telescoping wheelhouse so that the pilot can see over 2 containers stacked on top of each other. The second was designing/building a KORT SCHOTTEL drive unit.
The reason I am starting this blog is to see if any others have build their own Kort drive units. Size wise, I am using a 2" dia. nozzle with a 1.75" propeller. I have the gearing/motor/rudder all worked out and operating, what I don't have is a good method for securing the back end of the propeller shaft to the nozzle. I am looking for suggestions on how to make an assembly that can be assembled/disassembled.
The attached photos are version 1 & 2 of what I tried, and a photo of the entire assembly.
Thanks in advance for helping. Jeff

Thanks for the reply.
I am not sure I follow what you mean. Just uploaded the 2 versions that I tried. See if that's what you are talking about. Version 1 is "clunky", and version 2 is not that strong.
Regards Jeff
I was suggesting version two which you have tried. This will certainly let more water through the nozzle. if you silver solder the legs to the Nozzle and silver solder a central ring to fit the prop shaft housing this would be structurally strong. Should be easy enough to devise a clamp from this ring to the housing
