What size trolling motor is needed for a 20-foot boat?

When it comes to boating, there are a lot of decisions to be made, including what size trolling motor to use. Trolling motors are essential for fishing, and they can help you move your boat through the water with ease. But? This is a question that many boaters have, and the answer is not always clear cut. In this article, we’ll explore the factors that determine the size of trolling motor you need for your 20-foot boat.

Size Matters

First and foremost, the size of your boat will dictate the size trolling motor you need. As a general rule of thumb, you should choose a trolling motor with at least two pounds of thrust per 100 pounds of boat weight. Therefore, a 20-foot boat weighing in at roughly 2,500 pounds would require a trolling motor with a minimum of 50 pounds of thrust. This will provide enough power to move the boat efficiently in calm waters.

Boat Type

However, the type of boat you have will also play a role in determining the size of trolling motor you need. For instance, if you have a heavy fiberglass fishing boat, you may need a larger trolling motor than if you have a light aluminum model. The type of water you plan to navigate will also influence your decision. If you fish in rough water or strong currents, then you might need a motor with more thrust.

Battery Size

Another consideration is your battery size. Trolling motors run off batteries and the size of your battery will affect how much power you can get out of it. If you have a larger battery, you can use a larger trolling motor to get more power. A good rule of thumb is to match the size of your trolling motor to the size of your battery so that you don’t drain the battery too quickly.

Motor Type

Finally, the type of motor you select will also affect the size of your trolling motor. There are two types of trolling motors: bow mount and transom mount. Bow mount motors tend to be stronger and more efficient, making them a great choice for larger boats. Transom mount motors are more suited to smaller boats and tend to have lower thrust levels.

If you have a 20-foot boat, you’ll need a trolling motor with a minimum of 50 pounds of thrust to move it around efficiently in calm waters. However, the type of boat you have, the type of water you fish in, the size of your battery, and the type of trolling motor you choose can all influence the size you need. The best way to determine the perfect size trolling motor for your boat is to consult the manufacturer’s recommendations and factor in all of these key considerations. By doing so, you can make the most of your boating experience and catch more fish with ease.
