Riva Stage 2 results
Got 73.9 at 7920RPM on a full tank yesterday, didnt get to run the tank empty figure that is good for 2MPH. Ran over 70+ with a passenger that was great.
Aceleration feels strong but not as responsive as my tweaked 14/19. Should I remove 1mm of pitch to get the RPM's and aceleration up further?
Tested those sponsons with a few 50MPH odd 90 degree turns, it thru me off and the lanyard sprung into my forehead (Just a little bruse)
Handling is awsome the bike is easier to keep straight in the rough stuff.
Let me know what you guys think about the results.

is that the 3 blade? You're right where i'm at with my 13/19 3 blade but you'r running 300 rpm less .

The 15/20R is a 4-blade impeller, I wished I tested it at 1/3 tank because with the Stage 1 full tank vs 1/3 tank made 2.5MPH more on GPS.
One thing I did notice was it was hard to launch and keep from lifting out of the water with the trim all the way down. I thought you only needed the VTS rod for the Stage 3?
I got more juice on tap for sure, now I want more consistent top end.
Saturday I plan to remove the storage bin, fire extinguisher and extra fuel, pop the hood open and run this 4ucker balls to the wall.

The 15/20 I am running is untouched, I am going to pull 1mm out of the trailing edges to get into the powerband and gain a little speed. I was runnning 72GPS with a tweaked 14/19 stage 1. I think my current prop is stealing some speed.
