At what horse power do you draw the line between 3 and four blade props? What prop will give me the best performance with my 150 crossflow Rude on a 17 ft bassboat. I know there are lots of varibles, I have a 3 blade 21 on it now. Also how hard are jackplates on a transom?, my boat is old and the transom was rebuild once already. I seems solid and I am considering a jack plate.
