No problems with this part using it on a Mercruiser Alpha I Gen II outdrive. Did my water pump maintenance and she's running cool as ever!

Ordered these to do my annual water pump/impeller service on my Alpha 1 Gen 2 outdrive.They fit perfectly (although much tighter than the old face seal...of course). The old seal was cracking at the bottom where it meets the impeller housing. I'm not sure why these aren't included in the Impeller kit. I'll always buy these two together:
