Vern,
I've forwarded your message to a friend of mine who's in the market for an amphib. I believe he's looking at a LSA amphib with the 4.5gph Rotax.....I suspect this might be more plane than he wants, but it never hurts to get the word out, and he may run with a crowd that may well be interested in your kit.
It's a beautiful looking airplane, best of luck to you!
Regards,
Keith
