Waterski.com has these for around $489 and another $190 or so for puller kit.  I bought this to stick on my mastercraft Prostar but then ended up selling it before I got this prop installed.  I can't guarantee it will fit your boat but I've supplied all the photos and info that I have.  The link below is to one that looks identical but can't guarantee its the same as they might have changed them since I bought mine. 

OJ 4 Blade 13X13 Propeller

Replace your damaged prop with this 13x13 4 Blade prop from OJ Propellers. 4 blade props are well balanced and add additional low end acceleration compared to 3 blade props. The original is a design handed down from the originator, Oscar Johnson. This hand finished 4-blade has been a consistent performer for many years and is a popular choice thanks to its performance and affordability. This prop is designed for inboard boats.

"Common applications for this prop are direct drive boats with a Drive Shaft and a 1:1 transmission including MasterCraft (1968 to 2002), Malibu, Moomba, American Skier, Gekko, Calabria, Sanger, Ski Supreme and Supra boats."
