How to identify your current propeller
Looking to replace the prop that you have installed on your boat? Here are the most common places to find information about your propeller (such as part number, model, pitch, and diameter):
- The center of the propeller (commonly known as the hub)
- The side of the propeller
Selecting the Right Propeller
Choosing the correct propeller can be a confusing process. We're here to help you identify some important terms when in the market for a boat propeller - with terms such as diameter, pitch, and material.
Here are some useful things to know about your propeller that can help you determine exactly what you need. Hover over the images below to learn about each one:
Prop 101: Diameter
The diameter is an integral part to the propeller design and must be appropriately matched with the pitch to provide maximum thrust and mid-range fuel economy.
To measure the diameter of a propeller, take the distance across the hypothetical circle that the propeller would make when rotating. Another way to measure diameter would be by taking the distance between the center of the propeller (called the hub) to the tip of the blade - and doubling it.
Prop 101: Pitch
The pitch is the distance a propeller would move in one revolution. For example, a 20-inch pitch propeller would move forward 20 inches in one revolution. The pitch is a trade-off between top speed and acceleration: a higher pitch would deliver higher top speeds, but with lower acceleration.
Your pitch is based on factors such as your engine, your boat's weight and hull style, and your current propeller: number of blades, diameter and pitch. For best results, consult with your dealer.
Prop 101: Material
Many boats are factory-equipped with aluminum propellers. Aluminum propellers are relatively inexpensive and suitable for general purpose use. Stainless steel propellers are more expensive but are far stronger and more durable than aluminum, while delivering increased performance.
