I'll stop there if you get my drift.
Thank you. I may have been on SBO at some point but I don't recall ever going to a Catalina site. Or maybe it spilled over from there into other forums?

Entirely possible. That's how misinformation spreads, people repeating what they read without any specific knowledge of their own.

I have to admit I wasn't that smart either I did not spread any misinformation but on the face of it this story clearly holds no water. Why would you need to secure an impeller 'for transport'? I guess it is something I wanted to believe since it is a minor pain to deal with that thing. Oh well, now I need to deal with the consequences.

In principle installing the new water pump should be very straightforward: just two bolts! It is a bit more tricky in my installation since I have the Indigo FWC system. The bracket that holds the raw water pump partly obstructs one of these two bolts. I will have to see how much disassembling this will require.

Well, without the snap ring it's possible the shaft could slide out of the pump during transport but that would require it to be shipped in a box with one dimension over twice than what is necessary. You're right, it's a ridiculous premise yet the internet experts persist.

Yeah, and if such a packing size would have to be used (why??), two inches of packing tape would serve just as well.
