Where is the boat propeller manufactured in the world?

Question

I need the answer for my project in Social Studies.

Answer 1

A boat propeller is going to be no different than a car or car part.  Depending on where the manufacturer (OEM or aftermarket) is, is where it is made.  That could mean that the same propeller is available made in the US, China, Brazil, Mexico, Canada, etc....

Answer 2

It depends on the manufacture.

For instance Mercury makes their props in

Fond du lac, Wisconsin

Oh, I've seen them built there

Answer 3

I'm sure there are several manufacturers throughout the world.  Without additional information, the only general answer I can give would be China.
