I just had my props rebuilt this winter. I was having a bit of vibration so I thought I would try thr props first. Mine are 4 blade 24X24 props. I had 1/2” of pitch taken off them so they are now 24X23.5 props. It cost $980 per prop. But the props are now almost perfect according to the before and after scans. I would take the boat out and get some baseline info as to rpm versus speed so you will know what you have now and can tell waht difference any changes you make provide. Run the boat in 2 directions 180 degrees apart and measure the speed at say every 500 rpms then average the 2 speeds at each rpm to see your actual speed.
