Hello, I am opening this section here, because I think it might be interesting for many of us to share information on commercially available propellers. The main information required next to diameter is pitch and hub-diameter. Others might be maximum allowed RPM and mounting details. Sometimes the only way of finding out is buying one. This is what I did for two different props. I will share the data here and hope others will share data on other props as well.

Honda propellers for small outboard motors (4, 5 and 6 hp) presented on La Rochelle Grand Pavois boat show 2017 was in aluminium .
We are using the JAVAPROP software where we input our motor RPM, available torque (Nm), thrust required at specific speed 5.5m/s, select the diameter we want and blades are designed for peak efficiency. I’m headed over to Simons 3D print shop this afternoon to get our new props, super exciting that we can exactly what we need on-demand
How are you running JavaProp? Java is not letting me open because of security risk. I try to ass an exception in Java for http://mh-aerotools.de, but it still won’t let me open Java Prop.
For anyone coming across this later, Java will not allow self-signed apps to run. So to get JavaProp to run on your computer, open “configure java” go to security, and add an exception for https://www.mh-aerotools.de. Then Java will allow you to run the application.
