## Understanding Trolling Motor Thrust and Horsepower

When it comes to trolling motors, understanding the concepts of thrust and horsepower is crucial for selecting the right motor for your needs. While trolling motors are typically rated in pounds of thrust, gas outboard motors are usually rated in horsepower. Although you can’t directly compare thrust and horsepower, it is possible to estimate the horsepower rating of an electric trolling motor.

Trolling motors, being electric motors, are commonly rated in pounds of thrust because the thrust represents the motor’s power to move a boat through the water. On the other hand, gas outboard motors are rated in horsepower, which is a measurement of the motor’s energy output. As such, the two ratings measure different aspects of a motor’s performance and cannot be directly converted.

To estimate the horsepower rating of an electric trolling motor, one can consider the wattage of the motor. By multiplying the amp draw of the motor by the voltage, you can determine the wattage. Dividing the wattage by 746 provides an estimate of the horsepower. For example, a popular Newport Vessels NV-Series 55lb Thrust Trolling Motor has a wattage rating of 624. Dividing this by 746, it would have an estimated horsepower rating of approximately 0.84.

Trolling Motor Rating Equivalent Horsepower
55lb Thrust Approximately 0.84
80lb Thrust Approximately 1.07
112lb Thrust Approximately 1.5

While these estimates provide some insight into the horsepower equivalent of trolling motors, it is essential to remember that thrust is more about force and control rather than top speed. Factors such as the type of water you’ll be navigating and the size of your boat also play a role in determining the appropriate trolling motor thrust. By considering these factors and estimating the horsepower rating, you can make a more informed decision when selecting a trolling motor for your boating needs.
