I guess buy a 17 and have cup pulled out of it to allow for RPM.
I doubt it will hit 6600, but it should get higher than 5000.
What is the overall opinion here. That is a huge rpm gap for such a small prop.
I have a really stupid question. Are props in your area measured in inches?
American Props are numbered by inches. Meaning Pitch = number of inches a prop will travel through the water with one 360 degree revolution. I am wondering if they are stamping with another measurement scale?

But this is at a high rpm, unlike what we are use to seeing with American BB Chevy engines. BMW engines make their torque/hp later, our BBC power comes on much earlier. The peak number of that BMW engine are impressive, but they a peaky engines... not very much unlike a turbo charged 4 cylinder engine (which is not good for a heavy boat). So what I'm trying to say is we don't have much experience with these types of engines. I think the Lambo engines which at popular in Europe are more similar to your engine. Those guys may be able to better advise you in prop selection.

Thank you for the correction.
Sorry if I offended you.

This is interesting. Ludva is running a BMW in front of an Alpha Gen2.
Everyone is right. The peak torque rpm is in the wrong place for a marine engine. Not enough low speed power.

I do think that motor has biggest gyroscopic moment
From 1300 to the 5000 speed in a minute
