Evinrude Propellers

Evinrude is a U.S. company that constructs outboard motors. Evinrude propellers are designed to attach to Evinrude E-TEC engines as well as other engines. Their motors give you the performance you need for your marine endeavors.

What are Evinrude propellers made from?

Bronze, aluminum alloys, and stainless steel are the most common materials used in motor props. These metals work well in a marine environment. They are corrosion resistant and have excellent thermal and electrical conductivity. Evinrude props are built with the same consideration for durability.

How do Evinrude outboard motor propellers work?

Evinrude propellers are powered by the engine spinning around a central shaft attached to the motor. The prop blades rotate, and this rotational thrust creates a forward motion like turning a screw at high speed. Refer to the list below for basic prop terms that may help you understand how the shape creates the forward movement.

  • Leading edge: The edge of the blade closest to the boat.
  • Trailing edge: The edge furthest from the boat.
  • Blade root: The point where the blade attaches to the hub or center shaft.
  • Blade tip: The edge of the blade or the furthest point away from the hub.
  • Blade face and back: The sides that face toward or away from the boat, respectively.
How do you choose the right propeller

Choosing the right propeller is the single most crucial decision while building your motor. However, several factors control how a prop will affect your boats performance, from diameter and pitch to ventilation. First, you need to ask yourself a few questions about what you want out of your boating experience.

  • What kind of boating experience do you desire?
  • What type of boat do you have?
  • How fast do you want to go?
  • What type of engine do you have (i.e., E-TEC, Jet, etc.)?
What is prop pitch and what kind do you need?

It is the forward movement of a propeller through one complete revolution measured in inches. This measurement determines how you decide what prop pitch you need.

  • Lower the prop pitch to improve acceleration speed and pulling power.
  • Raise it for lower speeds.
  • A higher prop pitch can still allow faster boat performance as long as the engine has enough power to run at a higher speed.
  • For a more flexible option, consider a CCP, which is a kind of prop with blades that can be turned on its long axis to modify the pitch.
