Here goes boys, I tested the Solas New Saturn 11" diameter 15 pitch, the PowerTech SRD 11.25" diameter 15 pitch, against my Yamaha black painted stainless steel 15 pitch and 16 pitch.
My boat had 3 batteries, 5 props, and a 48qt cooler filled with water.
I tested hole shot, that is the time it takes when at a dead stop hitting full throttle, when the boat breaks over.
Yamaha 16 2.9 seconds
Yamaha 15 2.7 seconds
Solas 15 2.8 seconds
SRD 15 2.4 seconds
Top end
Yamaha 16 40.9 mph
Yamaha 15 38.9 mph
Solas 15 38.1 mph
SRD 15 40.9 mph
RPM at WOT
Yamaha 16 6100
Yamaha 15 6200 rev limited
Solas 15 6200 rev limited
SRD 15 6200 rev limited
I have 10" setback and I measure height from measuring the clamp bracket to the transom.
The Yamaha props both run at 4" above the transom
The Solas ran 5 inches above the transom
The SRD ran 7" above the transom
I have a SRD 16 and a SRD 17 pitch on the way. The SRD was the most comfortable to drive, did nothing stupid, o bounce, no chine walk, smooth even pull all the way to top end. I have sold my Yammie props and ordered the PowerTech SRD
And before anyone starts, I know it does not jive with a prop calculator, the calculator says it cannot run that fast. All I can figure is that the SRD is a 15 pitch close to the hub and pitches up towards the tips. Can't wait to test the 16 and 17 pitch SRD's.
