The propeller on a boat determines how fast the boat goes, how well it handles, and how efficient it is. Whether you’re just cruising around or pulling skiers and tubers, having the right prop is essential for the best boating experience. If you’re looking for the best boat propeller, we have a selection of the best ones that will deliver the performance boost and fuel efficiency you’re looking for.

Selecting the right boat prop requires making considerations such as pitch and diameter and we also have a guide on how to choose the perfect propellers for boats. By the end of this article, you’ll be aware of the best options on the market and how to make the right choice. Below are our boat propeller reviews.    

How To Choose A Boat Propeller – Buying Guide



Propellers on boats are usually made of aluminum, stainless steel and plastic. Aluminum props are the most common. They are suitable for general boating and more affordable than steel. Stainless steel propellers are the ultimate props. They are stronger and deliver higher levels of performance and durability than aluminum. The downside is that stainless props are expensive. Some propellers for small boats are made of plastic.  


While you will be using your boat at sea level most of the times, there are times when you might be boating at higher altitude, for example, when exploring a mountain lake. The lack of oxygen at higher altitudes can reduce the amount of power the engine produces. If you will be boating at elevation, select a propeller with a lower pitch that will deliver more power.


Weight can also affect the performance of your propeller. If you have a heavy load, your engine may not be able to run at full capacity. It is therefore important to consider the kind of load you will be carrying on your boat so you can choose a prop with the right pitch and diameter. You can opt for two propellers with different pitches to compensate or simply have two different propellers depending on your circumstances.


When air from the surface or the gas from your exhaust gets pushed past the propeller blades, it can reduce their performance. This can cause your propeller to over-rev as it overcompensates. It is therefore important to choose a high-quality propeller where ventilation won’t be an issue and install it lower on the transom. Checking boat propeller reviews can tell you whether this is an issue with a specific prop.


Cavitation is where water vaporizes due to a lack of pressure on the propeller blade. An excess amount of this action can lead to erosion on the metal. This problem is usually caused by flaws in the blade, poor polishing and poor design. Having a high-quality prop can ensure cavitation isn’t an issue. You’ll also want to regularly inspect it to ensure it stays damage-free


There are two key numbers to consider when deciding on the size of propeller to choose. The diameter is twice the distance from the center of the hub to the tip of the blade. Generally, the larger the diameter, the larger the engine it can be installed on. The pitch is the adjudged distance that a propeller will travel during one rotation. Pitch can be seen in the same was as gears on a car, so sometimes you need a lower pitch to get your boat moving.


Both three and four blade propellers work well. The three blades option will give you performance as well as a higher top speed while a four-blade propeller will work well with more difficult conditions and boats where top speed isn’t as critical. Four blade options will increase your fuel economy but decrease your RPM.



Q:  Why Do I Need A Boat Propeller?


You need a boat propeller to move your boat through the water. Boats propellers have long been the most common way for boats to travel through the water. It spins and thrusts your boat forward into the water. For top speed, optimum performance, and fuel efficiency, you will need the right prop for your boat and adventures on the water.

Q: Should I Store My Boat Propeller With The Boat Or Separately?


You don’t have to detach your propeller from the boat. The most important thing is to ensure that the propeller is dry and safely stored away until the next time you use it. With this in mind, it’s important to find the perfect propeller boat cover to keep your boat safe when it’s not in use.

Q:  What Type Of Maintenance Is Needed?


The propeller on boat requires regular inspection to see if there is any damage. Even though the propeller has corrosion protection, you want to make sure that it stays dry when it’s out of the water. If there are any signs of damage on your propeller, then you need to ensure that it is either repaired or replaced as soon as possible.

Q: Will A 4 Blade Prop Make My Boat Go Faster?


A 4 blade will make your boat accelerate quicker and also come to plane quicker. While switching to a four blade propeller will improve handling and performance, these benefits can come at the expense of top speed. If top speed is your priority, opt for a stainless steel prop or a 3 blade propeller.

Q: What Pitch Prop Will Make My Boat Go Faster?


A higher pitched prop on a boat will make the boat go faster. The higher the pitch the longer the distance the prop will travel through the water with each revolution and the faster your boat will go. Your top speed will be higher but the acceleration will be slower.  

Q: What Do The Numbers Mean On A Boat Propeller?


The numbers on a propeller for boats are its specifications: pitch, diameter and number of blades. The smallest number – 3 or 4 means the number of blades the prop has, the smaller number such as 14 is the diameter of the propeller while the largest number tells you what pitch the prop has.

Globo Surf Overview

Having the best boat propeller is important for optimum performance and fuel efficiency. Taking into account aspects like the diameter, pitch and the materials will ensure you select the best marine boat propeller so you can head out onto the water with confidence. Whether you’re looking for a motorboat propeller or a performance boat propeller, all the options are covered in our boat propeller reviews.
