The minimum hp for a 13' was 9.9 hp. Your 13 is a little heavier than the old blue interior hulls but your 15 Honda should plane easily with just you.
It won't cost you anything to try it. I would assume you would have to go down in pitch on your prop because the inflatable was a little lighter. \Let us hear how it goes.
