BX23 water pump questions

[tshep]

So, situation is BX/54 mower runs right up at orange with tall grass.
Recent work shows clear radiator (in and out), minimal internal rust, etc.
I believe I would NOT trust the water pump next.
I got tractor only a few years old.
Is it likely the original pump was a cast or formed (SS?) impeller?
Long term - should I seek OE or other water pump, formed or cast?

I've said it before, you really need to put the tractor letter designation on after the number
because there is a BX23D and a BX23S completely different tractors.
You have a BX23D
