IMPORTANT: To ensure proper fit, and performance, Mercury
Marine recommends the use of Mercury or Quicksilver branded
propellers and mounting hardware.
Propellers are designated by the diameter, pitch, number of
blades, and material. The diameter and pitch are stamped (cast)
into the side or the end of the propeller hub. The first number
represents the diameter of the propeller and the second number
represents the pitch. For example, 14x19 represents a propeller
with a 14 inch diameter and 19 inches of pitch.
a - Diameter
b - Pitch ‑ Travel during one revolution
The following are some propeller basics that will help you
determine the correct propeller for your boating application.
Diameter ‑ The diameter is the distance across the imaginary
circle that is made when the propeller rotates. The correct
diameter for each propeller has been predetermined for the
design of your outboard. However, when more than one
diameter is available for the same pitch, use a larger diameter for
heavy boat applications and a smaller diameter for lighter
applications.
