When took the lower unit apart and disassembled the water pump the driveshaft had some scoring and a few burrs causing the top of the pump housing to snag up and not come off. Any ideas on what might cause this? they are about two thirds up the shaft. Thanks. I hope i didn't trash the top of the housing getting it off. There is some scoring now on the inside bit of the hole for the shaft. Thanks
