Thanks for all the input! I found a "old style" 2.5:1 cogged belt redrive that came off an Challenger ultralight. Not exactly the ratio I really wanted, but it should work OK. I can't use the redrive as is however, because it won't bolt directly to my engine. I plan to fab up a magnum type set up using the two cogged pulleys from the Challenger redrive instead of the 6 V-groove magnum. Saved quite a bit of money and if it does not work out, I'll invest in the magnum and go from there...

I'm still shopping for that 3:1 ratio redrive though. But at least now I have something to work with...Hey! it just occured to me with the rotax motor, the Fatcat will soon be a true Mini!
