Super Jet Quick prop question

[lazyt747]

I'm running a 13/17 Solas Concord right now. What is the general rule of thumb when figuring which pitch is best for your setup?

I have ridden quite afew skis with 12/17 and 13/17. Owners all love them.

I prefer the 9/15 Hooker. Not sure what magically Rule of Thumb your looking for. May want to post your setup.

I am just wondering how the whole pitch setting works. Mine feels pretty good, I'd just like to understand props a bit more. Mods below:

701
Ada 35cc head
Factory b pipe
Stock pump

Note peak smooth water RPM and throttle response, shoot for 7000RPM. An out of the box Concord 13/17 with stock nozzle is too much for anything less than a low port 771. Raise the trailing edge to 1.3"-1.4". from the blade above and bore the nozzle. It will feel like adding 10HP. Some port work will net even better gains when the pump load is low enough. A 61X exhaust port needs to be 20% larger than stock to make full power at 7000 RPM.
