Nothing wrong with experimenting, just do us a favor and start off with some slow steps. I too would be interested in how she performs, just remember that you don't have to use all that power.
This reminds me of when I had a 14' simulated clincker row boat with a 40 evinrude tiller circ:1966 on the back, I don't think I ever opened her up to full thottle. The floor used to move with the impact of the waves I was hitting. And it was kind of satisfying going faster than bigger boats with bigger engines, but I knew the limits and never exceeded them.
