    Choosing a prop is complicated. If you over pitch it will strain the motor leading to premature failure. If you under pitch you will get good acceleration, low top speed and high fuel consumption. So you need a compromise. Most good dealers will advise, as will the motor manufacturer.

    increasing pitch increases the blade angle so they take a bigger bite and turn slower

    Up increases the bight in the water.
