Hi guys

Can you tell me what this impeller is for?
I got with an SX-R but i dont think it fits. it feels to big and the shape is a bid od...
There is no numbers on it or anything.

What do you guys think?

Kinda looks like Kawasaki 440

Not a 440, the 440 prop threads onto the shaft. I am gonna say some kind of wetjet, tigershark or polaris prop....... never seen blades cut like that. plus it is alum. junk.
