New or repair?

That's kind of what drove me toward a replace versus repair option on the pump itself; taking the pump apart to weld repair the casting (a crack at the seam of a casting, which I could chase forever) and then trying to reassemble it just didn't seem like an effective option.

I'm going to pull the pump off tonight (to Chuck's point, for educational purposes with no risk if something goes wrong), I think that will tell me what I need to know about the difficulty in putting a new one back on.

Well I pulled the old pump off in about a half hour, 5 bolts (4 were hard to get to, of course, but not too bad) and a set screw. Still undecided on what to do.

Consumer Reports has a guideline on Repair or Replace when it comes to appliances, which kind of applies here.
I regret that I can only paraphrase it, since I don't subscribe any more.

Basically, you depreciate the item according to its lifetime. Let's say at your rate of usage the washer will last 20 years. 8/20 is 40% of its value is gone, so it is worth (.60 x $300) or $180.

You're going to spend $150 to repair a $180 item?

I have doubt the pump can be welded - it is likely an aluminum casting, and that's not a trivial weld to get right.

Can you sell the engine? If you can get $75 or $100 for it, does that change the equation?

Keep the old hose and wand as a spare - or use it and keep the brand new one as the spare.

Another game-changer: Can you find the pump cheaper somewhere? eBay and the interweb are miraculous, poke around a little and see what you get.

Last comment: try to figure out why it broke, so you can try to avoid it next time.
