I bought this water pump in unknown condition. When I finally received it, I found it was seized up. There was a lot of corrosion on the impeller that was visible by removing the cap from the inlet port. I'm guessing it was used with salt water and put away wet.
The tag on the pump is hard to read, but a quick search on Darley's website gives Model#: 2BE10YDN and NSN: 4320-01-387-2869.
I wasn't sure if the seize was rooted in the pump or in the engine, but figured the visible corrosion in the pump was a decent starting point. Besides, if the engine had problems, I'd need to take the pump off any way.

The main pump housing came off pretty easy. Removed the nuts, gave it a few taps with the rubber mallet and it came right off.

The impeller took a lot more persuasion, but eventually came loose with a combination of PB Blaster, heat, 3 pry bars, and a 3-jaw puller. After "gently" prying for way too long, I finally got smarter and tipped it over so the impeller was facing up, and soaked it with PB Blaster until I could see it wicking into the keyway. Eventually, I got the impeller to come off about a 1/4", which was just enough to get the 3-jaw puller behind it. Unfortunately, I munched the inboard head a little with the first small prybar. That doesn't appear to be a sealing surface, so if all goes well, I'll try to touch that up with a file.
