Could anyone tell me if more pitch = more top end and less pitch = better hole shots? I know this is true for gearing on cars and bikes, but not sure if this transfers over to boat props. Thanks VR

Re: The correct pitch

Keep in mind that this only holds true for similar diameter props. More pitch will reduce rpm and less pitch will increase rpm. More diameter will decrease rpm and less diameter will increase rpm. And don't forget cupping. Increased cupping usually increases top end speed and reduces rpm. Different props have different affects on the boat's trim angle and drag coefficient. <br /><br />The only true way to find the most efficient prop is by trial and error. :)

Re: The correct pitch

You need to aim for whatever pitch that will give you the max rpm at WOT. When you get there, additional tweaking will only bring down performance.
