Re & Re Waterpump Impellers in 250 SX

[VANGRADY]

I recently re & re'd my water pump impellers last fall and ran the machines twice without any problems. I then experienced overheat problems after the first start up of the 2009 season. Some of the local mechanics at my marina have suggested that maybe the impellers were inserted into the housing with the fins facing backwards to the rotation of the pump shaft. They say that either some or all of the fins could be stuck with the fin set in backwards or that the impeller might have become detached from the hub on start up if it was put in with the fins backwards. Based on your experiences can this happen??
Thank you.

Yes, need to drop lower unit and check water pump.
