Seadoo Pump On A Single Pipe Gpr
Well We Finished Testing Today, Jim, And Leo Busted There Asses . I Am Extremely Thankful That They Helped Me Acheive My Goals, But It Didnt Work. Not Enough Power.
Leo's Ski With The Ho Pump Hit 77.5
Then With The Seadoo Pump With A 4 Blade Hit 73.2
No Good. Well We Tried. It Is Definately The Way To Go On A Conversion But Not A True Gpr.
We All Are Burnt And Tired. Had Fun But Didnt Work . Oh Well

Are you guys going to try a smaller prop? Why not try a prop from a machine with a smaller prop that has less horsepower, it may still be more efficient than the yamaha varient and get the numbers and holeshot you want!

On a 13-18 4 blade it went 71.9 at 7420, on the limiter bigtime..
The next (different) 4 blade was steeper pitch 16-21 i believe, Jim pitched it up to 16-23 before installing it and it went 7320rpm at 73.2mph..
Then the 3 blade that i believe was the turbo engine impeller was too much, only could turn it 6500 rpms..
