Why do I get the feeling these impellors are being turned in the wrong direction?

Image 1 is a scan of a test engine … from my cockpit the prop turns clockwise and so does the e-shaft with an RD1-C -  as referenced to this scanned image.

 

Now look at these water pump impellors … if I wanted to move water I’d cup my hand and scoop it, not use the back of my hand.

Has Mazda got this wrong? Or am I missing something?

 

It looks like I’ll have to change the water pump, as the flange may be warped and the thread bosses are definitely burred.
