Just purchased my first jet boat.. 1979 southwind. has a 427bbc with a single 4 barrel carb. wet headers. berkely jg pump.
guy I bought it from said it was around 500 horsepower, it's an 18' boat
its completely stock.. no mods....no place diverter... 

 I know I want a place diverter.. question is does anyone have a similar setup?
 will a long or short droop snoot help? or straight snoot?
 will a ride plate help? do I have enough horsepower?
 also will a rudder help me?
 it has snaps that look like it has a windshield at one time does anyone know were I could find one?

 all new here.. never driven. also should I get a rudder
