Ok, so I bought a remaned water pump, and when I got it, I noticed that the fins on it are way different then on my old one. now, they are bigger so maybe they can move more water, but I just dont know. also, I hope it's just because the pump has all new seals and bearings in it, but it's a little stiff whne you spin it, while the old one is loose, and feels close to what a turbo would when you spin the shaft. I just wanted to check what's up with it?
Here are some pics:
