The water pump write up from Mike's makes it a point to say that the impeller is pinned. I don't see that mentioned in any of the catalog text for the other water pumps. How important is that? If a new impeller is not pinned, what is the best way to add that? What pin do you use?

Do you still need to grind some of the tip of the 3 impeller blades off, or is that old folk lore?
