Determining the Right Motor Size

The size of the motor you need for your pontoon boat depends on a number of factors, including:

The weight of your boat
The number of people you will be carrying
The type of water you will be boating on
The speed you want to achieve

To determine the right motor size for your pontoon boat, you can use the following formula:

Horsepower = (Boat Weight + People + Gear) x 1.25

For example, if your pontoon boat weighs 2,000 pounds, you will need a motor with a horsepower of at least 2,500 (2,000 x 1.25). If you plan on carrying four people and a lot of gear, you may want to consider a motor with a higher horsepower rating.

Choosing the Right Type of MotorInboard motors are mounted inside the boat, and the propeller is located in the water behind the boat. Inboard motors are typically more powerful than outboard motors, but they are also more expensive and require more maintenance.

Outboard motors are mounted on the back of the boat, and the propeller is located in the water directly below the motor. Outboard motors are less powerful than inboard motors, but they are also less expensive and easier to maintain.

The type of motor you choose for your pontoon boat will depend on your budget, your personal preferences, and the size and weight of your boat.

Getting the Right Size Propeller

The propeller is an important part of your pontoon boat’s propulsion system. The size of the propeller you choose will affect the speed and efficiency of your boat.

To choose the right size propeller for your pontoon boat, you can use the following formula:

Propeller Diameter = (Boat Length + 10) x .08

For example, if your pontoon boat is 20 feet long, you will need a propeller with a diameter of 24 inches (20 + 10) x .08).

You can also find propeller size charts online that can help you choose the right propeller for your boat.

Conclusion

Choosing the right motor for your pontoon boat is an important decision. By considering the factors listed above, you can choose a motor that will meet your needs and provide you with years of enjoyment.
