302 overheats. incorrect water pump?

The part number points to a Mustang II-era application, before reverse rotation pumps were utilized. Also, did you install it like that, with an open back? Most FSB water pumps after '65 have a backing plate that covers the impeller. Early open-back pumps fit timing covers that are specific to those years, IIRC.
 
Hey, that's just generic pic
I was just asking what is the propeller's correct rotation, if it is like circular saw (teeths pointing to the direction of rotation) or opposite
 
dude what I am asking is how do you know the one on the pic is reverse (ignore alluminium cover)

so if the one on the picture is reverse rotation it should spin clockwise (as you looking at the picture, or looking at it from driver's seat)

edit: right?
 
Sitting in the car, with the hood open so you can see the fan, the fan should turn counter-clockwise.
