Don,
If you want to be scientific about it, there are many ways to calculate boat speed and horsepower required for a desired speed, given a specific hull and propeller. I would suggest starting with this web site
http://www.csgnetwork.com/marinepropcalc.html
for reference. In addition, there is a well known equation that is based on a hull factor that changes with respect to a displacment or planing hull, length of boat, horsepower and propeller that will give you a speed calculation, but I can't remember where I saw it and have not seen it on the web. Perhaps someone else can help here.
Otherwise, just mount a 15 or 20 horse on that sucker and put a governor on it when the kids are driving........
