| With all my tests of different props, i have done more since i wrote that review, I have a better top speed with a four blade compaired to an average 3 blade. This is because of the effeciency of the a four blade. I have also seen very little effect of rpm with the forth blade. I know with larger boat with bigger motors the extra blade should decrease rpm 200 (rule of thumb) but have not found that to be the case on smaller outboard motors.
Overall the handling is better, and better hole shot with my four blade.
Please note this is a 25hp motor going 21-24mph (depending if i am going with the wind) in a tin boat, it isnt a ranger 620 with a 250 hanging on the back that has power trim and a hydrolic jack plate. So 1mph is a fairly big change for just a prop change. | |
