Re: bring back memories?
The runabout classes go from 15 cu in to 44 cu in and are stock powerheads with racing lower units, 10 to 12' boats they can be built by anyone but must come to the specs. for the class they are raced in. The DUX class boats (inflatable cats) run stock engines in the 2 smaller classes but the X class anything goes I have a freind that races in X and his 70HP Johnson will show 135+ HP on fuel, on a dyno.
