Pontoon boats are an incredibly popular option for people looking to enjoy the water. Their stable design and spacious interior make them an ideal choice for a variety of activities, from fishing to cruising and parties. But, when it comes to powering a pontoon boat, one of the most important considerations is selecting the right size motor.
- For a 20-foot pontoon boat, a motor that balances power and efficiency is ideal. Typically, this means a motor ranging from 50 to 115 horsepower (HP). A motor within this range should provide sufficient power for most recreational activities, including cruising, fishing, and light towing, while also maintaining good fuel efficiency.
- The right motor size also depends on how you plan to use the boat. If you’re primarily using it for leisurely cruises or fishing with a few people on board, a motor at the lower end of the power spectrum (around 50–70 HP) may be adequate. However, if you plan to engage in activities that require more power, such as towing water skiers or carrying more passengers, you might need a motor towards the higher end (90–115 HP).
- The weight of the boat, along with its maximum capacity, should also influence the motor size. Heavier boats or those frequently loaded near their maximum capacity will benefit from a more powerful motor. A motor with higher horsepower will ensure that the boat maintains good performance and handling even under heavier loads.
Determining what size motor is best for a 20 foot pontoon boat is no easy task, as there are a variety of factors to consider, from the size and weight of the boat to the type of activities it will be used for. In this article, we’ll discuss the different aspects of selecting the right size motor for a 20 foot pontoon boat.
What Size Motor for a 20 Foot Pontoon Boat
The size of motor required for a 20 foot pontoon boat depends on the intended use of the boat. For recreational use, a 40–50 horsepower motor would be sufficient. If the boat is going to be used for watersports such as skiing or tubing, a motor of 75–90 horsepower would be more suitable. If the boat is expected to carry a heavy load with multiple passengers, a motor of 115–150 horsepower would be recommended.
- Up to 40 HP for a 2‑stroke engine
- Up to 50 HP for a 4‑stroke engine
- 25 HP for a jet drive motor
- Up to 150 HP for an outboard motor
- Up to 115 HP for an inboard motor
- Up to 20 HP for an electric motor
It is also important to consider the type of motor. For pontoon boats, an outboard motor is the most common choice. The pontoon boat should also be matched with the right propeller to ensure optimal performance. Power trim and tilt system can be helpful for adjusting the motor height in order to achieve the right balance between power and fuel economy.

Types of Motors
When it comes to pontoon boats, there are two main types of motors to choose from: outboard and inboard. Outboard motors are typically used on smaller boats and are mounted on the outside of the boat, while inboard motors are mounted inside the boat and are more powerful.
Outboard Motor: Outboard motors are a popular choice for pontoon boats due to their versatility and ease of use. They are mounted on the transom of the boat and offer good maneuverability. Depending on the size and weight of your pontoon boat, you can choose from various horsepower options to provide the necessary power for cruising and water sports.
Stern Drive Motor: Stern drive motors, also known as inboard/outboard motors, combine the features of an inboard and an outboard motor. They are mounted inside the hull of the boat, with the lower unit extending through the transom. Stern drive motors provide good performance and handling, making them suitable for larger pontoon boats.
Electric Motor: Electric motors are a quieter and more environmentally friendly option for smaller pontoon boats. They are powered by batteries and offer a silent and smooth boating experience. Electric motors are ideal for calm waters and shorter trips, as their battery life may limit the overall range and speed.
Jet Drive Motor: Jet drive motors use water propulsion instead of a traditional propeller. They are commonly used in shallower waters where a propeller-driven motor may be prone to damage. Jet drive motors provide good maneuverability and are suitable for pontoon boats that navigate rivers, lakes, and other shallow water bodies.
Outboard motors are also more affordable and easier to maintain, while inboard motors are more expensive but offer more power.
- Types: They come in two types: two-stroke and four-stroke. Two-stroke motors are less expensive and require less maintenance, but they’re also less efficient and more polluting. Four-stroke motors are more expensive but offer more power and are more efficient and less polluting.
- Size: The size of an outboard motor is determined by its horsepower. For a 20 foot pontoon boat, a motor in the range of 25–50 horsepower is recommended.
- Types: Inboard motors come in two types: gasoline and diesel. Gasoline engines are more affordable and easier to maintain, while diesel engines offer more power and are more fuel efficient.
- Size: The size of an inboard motor is determined by its horsepower. For a 20 foot pontoon boat, a motor in the range of 40–100 horsepower is recommended.
Factors to Consider When Choosing a Motor
