The boat propeller pitch basically reflects the distance a prop moves forward in one revolution. There are many factors that can impact a propellers pitch or distance if can travel per turn. The size of the boat, the number of RPM the engine is able to output, the weather or water conditions, and even the passenger capacity. Some may tell you the bigger the pitch is the way to make the boat go
. faster, but that is not always the case. When the pitch is too large, it can actually steal RPM from the engine, which in turn can decrease the speed and potential to fouling the motor. The reverse is true, if you went with a smaller pitch the RPM would increase.
