Riva Pump Extention Info
For those that arent getting good results from this mod...
If your ski isnt getting good results, try adding the 2degree wedge....
I gained 1.7 mph doing back to back tests..... Give it a try, Ive heard it doesnt work but, it worked for me...
Hope this info helps.........

suposedly, it makes your ski really loose WOT... Before I added the wedge, my ski was very deep in the water at WOT. Now, the ski feels great.
Im running a closed loop Jims plate with this....
Try it. Its eazy to install and you could see some great speeds....

Good results Jessie but everyone must remember your results are not typical. 99% of people gain speed with the pump extension kit and it's recommended not to use the wedge.
Maybe your ski picked up speed with the wedge due to the ride plate your using or some other variable such as the pump shoe angle as noted above.

i think my rideplate has alot to do with it... my pumpshoe cant be the reason...
it was personally installed by Bruce @ Riva...
either way, if your not getting good results, its worth a shot..... it helped me for sure....
