Hello all! It's been a while...
So, I pulled the 194 from the Nova... 250 is in! As I'm buttoning things up, I found the fan bolt pattern on the 250 is larger than that on the 194! I have a pump with both bolt patterns, so I pulled the one from the engine... the impellers are different! The one has a plate on the back side covering the impeller. The one that came off the engine, the impellers are curved the opposite direction!!!!!!!
Are there engines that spin the water pump in the opposite direction? Should I install the dual pattern pump?
