Welcome to the new Wizard Outboard Forum.
I have a lower from P.H. down with prop , not sure of the mdl. but it's very similar to kh7 mk20 f/n/r lower.
Model # should be on a plate on the backside of the swivel brkt. It is from a Wizard Shift motor, Models WH7 Powermatic 10 or WN7 & WN7-A Powermatic 12's
