this is real progress on props. we are getting it now because we can use 3d printing to mock up trial props for testing. In the past it meant cranking up the machining tools and every best guess was only so good.
I do think that the big market will be in the water. They have to find a way to cast them and finish with machining. Yet every outboard needs this and every power boat. That number is actually finite and we can tune them with printed props in order to get them right. Then apply speed with metal and perhaps some trim then
We have needed a better prop solution forever.
