engines

Whats the differance between the super pro the semi pro and the pro the 7.5

1) seducer model complete hardware new motor mounts no motor or pipe. some extras (new 3/16 cable, strutter for 1/4 inch, new 2oz tank) beautiful paint couple of light scratches one chip on nose of boat repaired you can see it in the pictures. 2) new picco 90 hydro with carb. 3)...

Was wondering if anyone on this inter web ever had any luck with the 91HRs before the VACs came along. what pipe did you find worked and props for the riggers be twin or single. Just thinking about putting some NIB engines to work in the F hydro class.
