Y'know, Guus, you might want to do what I did.
I had lots of confusing advice when considering a feathering prop. Finally, I found a company called "Kiwiprop", in New Zealand
(where else, with a name like that!).
John Blundell, the proprietor, gave me a list of boat parameters, and instructed me on the specific information he needed. They then sold me a prop, sized and pitched accordingly. The price
was also very competitive, delivered to my door, in the USA.
These props are stainless, with replaceable plastic blades. The mechanism is quite simple, so you can service
it yourself, at haul-out. You can perform any required pitch adjustments, after re-launching the boat, in the water
with just a small allen wrench. (I stuck the wrench into the end of a piece of wood dowel, so the diver wouldn't lose it.)
I have put over 1600 engine hours on the boat, since installing that prop, and it has performed flawlessly. As it goes into "full pitch" astern, it will exacerbate any sideways a'pull' when starting out, but that has not been a significant problem.
At each haul-out, I dismantle, clean, inspect, lube and reinstall it, using basic hand tools.
After six years, I couldn't be happier. I am sure Mr Blundell could help you too.
