John,
The rotors on all of the Turbax units are the same except for the adapter hardware. What distinguishes a Turbax I from a Turbax III is this adapter hardware and the motor mount on the fan unit itself. Is the motor mount for a 40 size engine (Turbax I) or for a 77-90 size engine? (Turbax III) Next, you will have to determine which engines will fit the fan unit by determining how the engine mount was drilled and what adapter hardware you have.
