Need to know where to start prop wise on my GPR project! Please help with some advise and input. 02 GPR ported Riva Super stock motor with Factory triples,Advent and Riva gas valves. Installing a 07 H/0 pump. Have read that people run 14/20 on modified crafts. Any suggestions? Also brand recommendations? Also Nozzle suggestions? Thanks in advance for any help!!

1200cc ? If it can turn a dynafly 14/20 7800rpm or more that probably going to be the best all around. Some have to set down to a 13/19 to get enought rpms though. But if its setup well it should turn the 14/20

frank, get a good tach, start with a 14/20 DF with a 85mm nozzle. I would start there to see were you are.

I had no problems turning a 14/20 with a 85mm nozzle at 7900 to
7960 rpms on my stock unported 1200 motor, Pro-tec head, and
a Pro-Tec rev limiter. Also with stock reeds and stock carbs.
I think you will be fine with your superstock setup.

7960 rpms that's ideal for my setup correct? Also may be a stupid ? But I'm new to this H/O pump stuff. When I'm looking for a 14/20 prop I would have to say its for a 05 SHO or would it still be the same as a 02 gpr wich the ski itself is??? May be stupid but I'm leanring . Thanks Frank
