Flexifold and strut
First off how does one remove this propeller?
Second, sorry about not having a picture that shows more but after I took the picture I got to thinking that this home made strut may not be as strong as it should be.
They guy put on a much longer shaft so he could fit a larger prop.
You can pretty much make out the size of the new strut.
The unsupported section is maybe two feet.
I suspect it is strong enough to drive the boat I'm just thinking that even a minor event like a prop wrap will bend it causing immediate failure.
The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.
