props for #4 speedmasters
 

Looked at a fountain withe #4,s . Props are to big , the motors only turn 4500 rpms.But at 92 mph. Is this to much strain on the drive ?Can I get these props worked from 31,s to 29,s . Wouldnt this take some strain off the drives, shafts, and probably a few more MPH ?Gear ratio in drives was 1: 30.

Im sure ya, ll have been following my lead the last couple of weeks . 1000 hp huffers in the boat . 572/ big mega huffers

Well, did ya buy it? I saw the pictures and it looks awesome.
You probably will get better responses to the prop questions in the Prop section of the forum. I am sure Throttle Up or BBlades will have some good suggestions to hook up all of that horsepower. Not sure but, I think you have to run cleavers on the #4 speedmasters. Maybe replace the 3 blades with 4 blades. Good luck!

At what RPM is the peak HP produced? First and foremost we should look into the torque band of the motors to make sure you run them were they are happy and HEALTHY!
