Hydro powered by 600cc F2

[Hydro600]

I have plans from Clark boats for a ride behind hydro plane race boat. The original plans called for a Crosly engine. I am going to use a 600cc 4cyl water cooled motorcycle engine for a power plant. These are engines that mico sprints use at my speedway.
The reality of building the boat is to create a competion series for all owners. The engine is spec., and all boats will be basically equal.
I am looking for expertise in hydro plane engineering. We want to build one boat, test it, and take it on the boat show circuit as a marketing study.
Pricing will be less than large personal water craft, and when you buy one you are automatically in the series.
What are your thoughts?

Make sure it is legal to race that exact boat in another class in case someone gets bored, or finds that there is no-one to race against on his side of the country.
