Best Hydrofoils for Outboards

A lot of people might not be aware of this, but there is an effective way to enhance the performance of an outboard with just a device. This device is known as the Hydrofoil.

However, the hydrofoil we will be talking about in this article is a little bit different from the usual ones which are normally connected to the bottom hull. This is because they are attached to the cavitation plate of the motor instead.

It should, however, be noted that while Hydrofoils indirectly increases the efficiency of the outboard, it does this by minimizing drags that occur as a result of water resistance. This will also result in an increase in the efficiency of engine and fuel consumption. This is why the installation of Hydrofoils for outboards is very beneficial to boats.

However, as a result of the wide range of hydrofoils available on the market in recent time, it is very challenging to pick the best hydrofoils for our outboard motors.

What Is a Hydrofoil?

A device used to minimize drags on a boat by raising the boat in the water as it increases its speed gradually. So this means that the greater the speed of the boat, the higher they raise the hydrofoil will provide. These Hydrofoils often comes with a triangular design similar to that of a fish’s tail fin. It is often attached to the outboard motor that can be found just above the propeller.

Important Factors to Consider when Choosing a Hydrofoil for Your Outboard


You will find that most hydrofoils are made with plastic and not just any type of plastic but the ones that are very strong and durable so they can handle the impacts of water waves properly while maintaining flexibility.

However, there are a fair amount of hydrofoils that are made from other materials like stainless steel or aluminum. Both of which are also very strong and durable. Of the two materials, Stainless steel is more durable and lightweight but more expensive.

Most aluminum hydrofoils often have a specialized function like provision of balance or stability.

Vessel Size

The size of your boat is an essential factor to consider when you want to buy a hydrofoil for your outboard motor. This is because there are some hydrofoils that work better on larger boats while others work better on average-sized and small boats mostly under 20 ft.


Mainly you will find that there are two mounting options for outboard hydrofoils and they are;

  • Clamp-on Hydrofoils
  • Drill Mount Hydrofoils

Generally, the best option is the drill mount option because it helps attach the hydrofoils to your boat better. But since this will require drilling, it will probably be better if you go for the clamp-on if you are not that good with tools.

The main downside to using the clamp-on model is that they can easily slip off while the drill mount will remain in position no matter the condition.

Engine Compatibility

The capacity of your boat engine is another important factor that should be taken into consideration when you are planning to buy a hydrofoil. There are a lot of engines that have too much power and will require a hydrofoil that can handle that kind of HP. There are some hydrofoils that work well with larger boats of bigger capacity, and there are others that work well with boats of normal engine capacity.

Speed and Fuel Usage

One of the effects and benefits of hydrofoils is to improve your boat speed and also the fuel efficiency of your boat. So this is why it is important that you consider the rate at which your boat speed will be improved when you are choosing a hydrofoil to buy.


Price is another essential factor to consider when you are planning to buy anything. Before you buy anything, you will probably have set a budget for that reason, and you will not want to exceed that budget when you buy the hydrofoil. The prices of hydrofoils are generally very different due to the wide variety of materials used and their functionality. But you will find that the average price of a hydrofoil is $30 while some top-end own might cost up to $150.


This is for your own good because you can never be 100 percent sure that the hydrofoil you purchased will be compatible with your boat or fit on your cavitation boat. In any case, getting a hydrofoil with a warranty will help make sure that you can return the hydrofoil within the set period of time if the terms of the warranty are not broken.
