I found one statement to the effect that Gates is an OEM on the pumps:
2011-2012 Subaru WRX Gates OEM Water Pump: JSC Speed
However I'm not worried about it either way; I'd use Gates on any of my vehicles in any context except for gaskets. I did not like the Gates gaskets. Although everything else (rollers, tensioner, belts, pump) is such that I could not distinguish it from the Subaru labeled analog, the gaskets did not do it for me. Just my view.
That being said it's hard to tell. It's been a while since I've seen a gates pump but when I did it wasn't the same kind of consistency of the stock pump. That being said I haven't seen a newer subie that needed a pump so for all I know they could be manufacturing them for subaru now.
I noticed the blade enclosure but not much else. I've spoken to Gates and sent questions and they were very helpful. Interesting.
That wasn't part of the discussion. We discussed the markings on the timing belt and the manner in which the exit ports on the water pump are fitted onto the body. If I'd thought of it I'd have asked though. Oh, well, I'm up for another in 90,000 miles so I can ask then.

Hmm, interesting. I'll see if I can get a look at one and take a look at the markings on it.
Ok good thinking.
Yeah I used a Gates kit. All the idlers were the same brand and model as the factory. The tensioner was made by the same Japanese outfit that made the OEM one. The water pump was 100% indistinguishable in every way from the OEM one. The OEM one has no markings on it, neither did the gates.
I concur gates gaskets are crap, I bought OEM.
I now recommend also inspecting the thermostat housing carefully and replacing that as well if there is pitting. Again just IMO and I am no mechanic -- on the contrary my tools are a waste, I can barely use them so everything I say needs a grain of salt.
