The motors you ask about belong to a friend, Walt Chute from Niagara Falls. He had a description sheet for the power pak and the white setup. The Lauson was some kind of small inboard prototype. The Power Pak motor was a small air cooled 2 cycle inboard motor that had a small in/out box attached to the output shaft, and the white one was a german made Wankel motor setup for a small ski behind (on a rope w/controls) device that was pretty dangerous, I imagine, as it didn't have a kill switch. I think he got them at the Mystic meet in CT this year.
