l seen on this site that you guys over there pressed the water pump impella on a certain measurement.our guys over here press them on so bearing sits against shoulder on the shaft.I tried your way once and the impella scraped on the inside of the water pump cover. What is the right distance?

The book says 24mm of shaft protruding from inner bearing race is correct distance.
What book?

Looked at my 2003 Honda SM and the shaft is pressed all the way to the inner race. No measurement is shown or mentioned. If it is not pressed FAR enough into the inner race, then I can see it might hit the cover.

The service manual had an addendum in 06 or 07 that changed the press depth of the impeller.
