Best hydrofoil for outboard motor – Buying guide for boat owners

Sometimes, the simplest things make the biggest difference. That’s the best way to describe a hydrofoil. A hydrofoil works to increase the performance of the outboard, giving you a seamless boating experience. Once you get this simple installation, you will realize what you were missing out on! In fact, the hydrofoil is such a great device that you will never find a boater say anything against it. 

Let’s dig deeper into this wonderful world of hydrofoils and help you understand which one to buy.

Benefits of a hydrofoil

The hydrofoil works by reducing the drag and elevating the boat as its speed increases in water. The lift you get thanks to the hydrofoil is directly proportional to your speed. A hydrofoil for the outboard motor will remind you of a whale’s fin and it goes above the propeller.

Once you get the device installed, you will enjoy the following benefits:

  • Better fuel consumption
  • Easier handling
  • Boosted performance
  • The motor will live much longer 

While a hydrofoil is indeed a great buy, you must ask yourself if you need it. It has been designed to solve a few specific problems and if you are not experiencing any of them, you do not need to invest in it. Here are the problems we are talking about:

  • The bow bounces
  • The boat has a hard time staying straight in the water
  • When the motor trims, your boat ventilates

Things to remember while buying a hydrofoil for the outboard motor

We shall quickly gloss through our buying guide before we jump into our best picks. Below are the factors you must consider in order to make sure that you have the best boat:

  1. Material: Plastic hydrofoils are very popular and recommended. But there are stainless steel and aluminum options as well. The latter ones are expensive though.
  2. Mounting: You can choose from clamp-on and drill mount hydrofoils. If you do not like tampering the boat, choose clamp-on. Otherwise, drill mount devices are more durable.
  3. Size: If your boat is larger than 22 feet, you should not buy a hydrofoil. It is not going to help. All experts are very clear on this – hydrofoils are for smaller boats.
  4. Compatibility: Yes! Much like in other cases, compatibility matters here. To ensure this, you must take the power of the boat into consideration.
