Offered for your consideration: Kawasaki KHI 59255-3729 Impeller. I would like to mention that I do not have extensive knowledge in these, so make sure to do your research prior to the purchase. As you can see it comes in a box, the problem is, I am not sure if the impeller belongs to the information on the box. On the box it says: Kawasaki  model 148-75 Swirl. Pitch 13/17. From what I can see this is brand new, pictures should clearly show that it has never been used. Please feel free to contact me with any questions (perhaps, the weight or may be measurements)  or if you like to see more photos.
