    Do some searching on here. Someone did this a few years ago. Never did see or hear how it turned out. He had to cut up the top deck alot to get the 250X engine in.

    Also, I saw another build, but he didn't give much info, where he took the top deck off a 250X cut it up somehow and put it on a 15F hull.
