I'm trying to match up the number with the 2003 GTX DI. The number I see on the impeller is QC000923. Those are the only markings I see. I am looking through a mirror so sometimes it is difficult. LOL I've looked it up and do not see that number. The Seadoo Number is listed as 271000920. This is the pump I removed from the GTX DI.... I want to verify it is correct before I put it back together. Help is appreciated.
