1974 jet drive

I have been around your site a couple of time over the last couple of years . It is a great source of info on these boats . I'm looking at a 1974 I/O that will be a project boat over the next year if I can buy it right . I noticed a jet drive model in the 74 catalog . Is anyone running one ? It loks like a cool boat . But I don't see a jet drive for myself . The motor on this boat has not run in about three years and I most likely will replace with a bracket . If I can get some pictures next Saturday I will post them and get you guy's thoughts .
