Lynn,

Don't go out and buy a tester on my account. I was just curious what the 2200 modified would do. I doubt you would have gone so far as to build a set of amphib floats if you didn't think they would work.

It's actually pretty simple; if you think your jabiru speedster will compare at all with a rotax speedster performance wise, it's probably going to work on floats similarly. So we just need to get those floats on to figure it out.

The biggest question I have about this is if your existing prop will have enough thrust being that it is so short? It would be interesting to talk with either jabiru or lonnie prince to see if you could run a longer prop. I've heard of guys with jabs running 64 and 68 inch props with success. But again, that's just my idea. Your existing prop might be just fine.
