If you’re looking to improve the performance of your outboard massively, then there is one simple installation that you can add to the outboard: the hydrofoil.
A good hydrofoil will level out your ride and make it smoother, reduce porpoise, and possibly even increase your top speed! So this one simple fix can completely change your ride.
However, if you don’t know which hydrofoil to choose, then you’re in the right place.
If you are in a hurry and just want to find out what is the Best Hydrofoil For Outboard Motor, then I recommend below As the best ones.

What is an Outboard Hydrofoil?
An outboard hydrofoil, sometimes also called an underwater fin, are wing-like surfaces that are mounted to outboard and are designed to lift a moving boat at both low and high speeds.
They help lift a boat’s hull clear of the water, which can result in drag reduction at higher speeds without needing additional horsepower. They are designed like a shark’s tail, and they are usually attached below the hull.
Hydrofoils have been around ever since 1908, but only recently, they have been gaining on more popularity. Today, more and more outboard owners are deciding to add hydrofoils to their boats in order to improve the quality of the ride, decrease porpoise, and maintain the plane better.
What Does a Hydrofoil Do On an Outboard Motor?
A hydrofoil will greatly reduce the drag on your vessel as it will elevate the boat in the water when it starts to gather speed. A hydrofoil is designed in such a way that it looks like a shark’s fin, and the faster you go, the more lift the hydrofoil should give.
When the hydrofoil is planted near the hull, it will create enough lift in order to raise the hull from the water. That, in turn, will reduce the porpoise, and it will help you keep your plane no matter how fast you are going.
Smaller outboards will enjoy a much bigger performance boost than larger outboards.
This makes your outboard more fuel-efficient, the ride will be better, and in some cases, you will also travel faster!
A good hydrofoil will help your outboard plain better, and it will also help you maintain plane at lower speeds. This will greatly improve the ability to cruise at lower speeds and maintain your plane even at higher speeds.
Porpoise will also be massively decreased, and it will improve the overall quality of your ride by quite some margin.
Why Should I Get a Hydrofoil for an Outboard Motor?
A hydrofoil for an outboard motor has several benefits; but if your boat is already performing well, then a hydrofoil would be a waste of money.
However, if you are experiencing the following performance issues, then a hydrofoil would be very beneficial:
- If you are experiencing excess porpoise (which means that your bow bounces up and down too much). These porpoise landings can not only be uncomfortable but also dangerous!
- If you are experiencing too much side-to-side rocking.
- If you have trim issues.
For those who are experiencing any of these three problems or all of them, they should definitely consider trying a hydrofoil for their outboard motor. Some say that a hydrofoil can increase the speed, although that’s technically not true; you might only see a very tiny change to your top speed.
How to Choose a Hydrofoil for Outboard Motor?
There are several factors to consider when you’re choosing a hydrofoil for outboard motors:
- Build quality
- Compatibility with your engine
- Boat size
- Installation method
When it comes to build quality, we have to talk about the materials that the hydrofoil is made from. Most of these hydrofoils will be made of plastic; however, it might not sound quality, but rest assured. This plastic is the top-quality and durable plastic that will make the hydrofoil withstand heavy pressures and it will also be lightweight.
Compatibility with Your Engine
Arguably the biggest consideration you should make is whether the hydrofoil is compatible with your engine. Some engines are just too powerful for certain hydrofoil options. And make sure that the hydrofoil you buy is completely compatible with your engine.
It’s very important that you choose the hydrofoil for your boat. Smaller boats will see bigger improvements than bigger boats, so you should not consider a hydrofoil if you have a boat that’s bigger than 22ft. For larger boats, these hydrofoils might not have that much of an effect; however, for smaller boats, these hydrofoils will work wonders.
It’s better to buy drill mount hydrofoils rather than clamp-on hydrofoils – that’s what most experts agree with, too. The reason behind that is that clamp-on hydrofoils are not as reliable as drill mount hydrofoils, and might get removed from the engine easier than drill mount hydrofoils.

So now that you know what are the factors behind a good hydrofoil, here are the products that fit the requirements the best.
1. SE Sport 300 Hydrofoil
The best feature of the SE Sport 300 hydrofoil is its build quality. It is made for endurance and for longevity, and it will also work with more powerful engines – which is something that less durable products are simply not capable of.
With this product, you will see massive performance increases – it will help you eliminate the drag, which can increase the satisfaction when you ride your boat. It also offers you improved thrust which can help you adjust to plane at lower speeds.
You will get all the mounting hardware that you need in the package. Additional benefits of this hydrofoil are better fuel economy and greater control of your outboard.
This hydrofoil is suitable for a wide variety of engines – from the less powerful ones at 40HP to more powerful engines – all the way up to 300HP. We have noted that it might not be a good idea to buy a hydrofoil for boats that are larger than 22ft.; however, this product is perfectly capable of handling boats larger than that.
Installation is easy, and the product is also not pricey; overall, we believe that this product will massively improve your boating experience, which makes it a no-brainer.
2. Davis Doel-Fin Outboard Stabilizer
The Davis Doel-fin hydrofoil brings an amazing performance to your boat at an affordable price. This hydrofoil is made from durable and high-quality plastic, so it will last you for significantly longer than some other plastic products.
