Propeller Basics


Pitch - The theoretical distance, in inches, that a propeller travels forward during one revolution. Think of pitch as speed. The higher pitch propeller the engine can turn, the faster the boat will usually go. You only need to choose the correct pitch propeller for the boat and engine. The correct diameter for that propeller has been predetermined by the engineers at the various manufacturers.

Four Blade Propeller Facts
  • Plane the boat faster than 3-blade propellers
  • Keep the boat on plane at a lower speed
  • Give improved mid-range speed at the same RPM as a 3-blade propeller
  • Provide quicker acceleration than most 3-blade propellers
  • Run smoother than 3-blade propellers
  • Have better holding power in rough conditions
  • Are less likely to ventilate in sharp turns
  • Provide better low speed handling
  • Are not quite as fast on the top end as a comparable 3-blade propeller
