I recently tried to install a new impeller for the Oberdorfer raw water pump on my Universal M40. While it looked identical to the one removed it did not leave enough room on the shaft to allow replacement of the split ring.
When asked, Torresen Marine said they had not heard of that problem before, but that the split ring was not really necessary since niether the shaft nor the impeller were going any where once the cover was in place.
Sure seems like the designer must have had a good reason to use the split ring, but not having it will sure make the changing of an impeller easier especially if speed was important.
Has anyone run into this? Any thoughts on extended use without the split ring holding the impeller in place on the shaft?
