Welcome to the new Wizard Outboard Forum.
Thanks Birney for the sustitute part number. I was wondering if anything else was a close fit.
I ordered one to try from this website.
Do you happen to know what Brian Wilcox is charging for his K model impellers right now?
I contacted Bob Long, the flyingscott guy, and he has them in stock for $35 including shipping with your old core.
