Morning  Jeff,
 
The pump inlet is the long tube feeding water = into the=20 center of the pump housing and the center of the empeller blades.  = So the=20 blades are shaped to in a curve to "push" the water in the center = of the=20 empeller to the outside or the exit of the pump housing..  Yes, you = would=20 cup you hand to "scoop" up the water, but the pump does not "scoop" - it = pushes.  So at least that part of the Mazda pump design is=20 correct.

Why do I get the feeling these impellors are being = turned in=20 the wrong direction?

Image 1 is a scan of a test engine =85 from my = cockpit the prop=20 turns clockwise and so does the e-shaft with an RD1-C -  as = referenced to=20 this scanned image.

 

Now look at these water pump impellors =85 if I = wanted to move=20 water I=92d cup my hand and scoop it, not use the back of my = hand.

Has Mazda got this wrong? Or am I missing=20 something?

 

It looks like I=92ll have to change the water pump, = as the=20 flange may be warped and the thread bosses are definitely = burred.
