How to Choose a Fishing Boat Propeller and Stop Flopping Around

A fishing boat propeller is usually out of sight and out of mind. It’s down in the water pushing your boat from place to place, and people don’t give it much thought. But did you know the wrong kind of propeller can cost you excess fuel and affect the life and performance of your boat?

There are many factors associated with choosing a boat propeller for fishing. Read on to learn how to find the best fit for your boat.

Three Numbers to Know

Each propeller has three numbers associated with it. The first number is the diameter. The diameter of a propeller is measured across the outside circle of the blade tips. 

The second number is pitch. The pitch is the distance in inches the propeller moves the boat forward in one revolution. The third is the number of blades on the propellor – usually between two and six. 

A propeller for a fishing boat with the designations 15x17x3 has a diameter of 15″, a pitch of 17″, and three blades. Check your owner’s manual to see the range of diameters and pitches that are suitable for your engine. 

How to Choose a Boat Propeller

There is no perfect boat propeller. Each will provide a different aspect of performance, so it’s essential to identify what matters most to you and choose the propeller that provides that.

A three-blade propeller is efficient, but a four-blade propeller gives you a faster start. A lower pitch will move the boat more slowly, which is important if you fish in rough waters. And each engine manufacturer recommends props that meet specifications.  

To make sure your propellor is the right fit for your boat, use a propeller sizing guide. Propellor Depot can help you find the perfect boat prop for your outboard, sterndrive, or ski/wake marine engine. Your fishing trips will be more enjoyable and productive with the right propeller.

Propeller Materials

The two most common materials used in propeller construction are aluminum and stainless steel. Aluminum is less expensive than steel, and there is a wide selection of diameter, pitch, and number of blades. 

Steel propellers are more durable and withstand almost any contact. A well-built steel propeller will probably last the life of your boat. They also perform better because the blades have much less flex than aluminum models. 

Make the Right Choice

Knowing how to choose a fishing boat propeller can make a big difference in efficiency, power, and performance. There is no one-size-fits-all boat propeller, but you can use different models to enhance different aspects of your fishing experience. 

If you need to navigate rougher waters, choose a propeller with a lower pitch. Need to get from one fishing spot to another quickly, choose more blades and a higher pitch. Check the owner’s manual of your engine to ensure you choose a propeller that’s within the manufacturer’s specifications.
