Ever wondered what the numbers on your prop actually mean?
Prop pitch is essentially the distance a propeller would move forward in one revolution if it were moving through a solid material. Change the pitch, and you change how your engine performs.
A lower-pitch prop will generally let your engine turn higher RPM and can improve hole shot and acceleration.
A higher-pitch prop will generally lower engine RPM and may increase top-end speed, but too much pitch can keep your engine from reaching its recommended operating range.
As a general rule, changing pitch by 1 inch can affect engine speed by roughly 150 to 200 RPM, although the actual difference depends on the boat, motor, prop design and setup.
The goal isn't simply more speed. It's choosing a prop that lets your engine operate within its manufacturer-recommended wide-open-throttle RPM range while delivering the performance you want.
