How Much Thrust Do You Need To Move A Boat?

A 28-pound thrust trolling motor can be used to move an aluminum boat. However, the speed will be relatively slow, and it may not be suitable for rivers or larger lakes. A 30-pound thrust trolling motor can achieve a speed of around 2-3 mph, while a 36-pound thrust trolling motor can provide adequate power for fishing but may not be sufficient for rough water conditions. A 45-pound thrust trolling motor is recommended for a 14-foot aluminum V-hull boat, and a 55-pound thrust trolling motor can offer even better performance and longer battery life.

A 28lb thrust motor is suitable for a 14' aluminum boat

A 28-pound thrust motor is suitable for a 14-foot aluminum boat. However, the speed will be relatively slow, and it may struggle with additional weight or windy conditions.

A 28-pound thrust trolling motor is likely to provide a speed of around 2-5 miles per hour, which is standard for this size and type of motor. It will be adequate for fishing and moving around small ponds or lakes with calm water. However, it may not be powerful enough to effectively counter wind resistance or carry multiple passengers.

If you are looking for faster speeds or need to travel longer distances, a more powerful motor would be advisable. Upgrading to a 55-pound thrust motor or even a small gas outboard motor in the 2-5 HP range will provide a significant boost in performance.

For a 14-foot aluminum boat, a 9.9 HP outboard motor is a popular choice and should provide satisfactory speed and power. If you require more speed, a 15 HP motor is another option, but ensure that your boat's transom can handle the higher horsepower.

Additionally, consider the weight and ease of use when selecting a motor. Electric trolling motors are quieter and more lightweight than gas outboards, making them easier to transport and store. They are also suitable for use in areas where gas motors are not permitted.

In summary, a 28-pound thrust motor will work for a 14-foot aluminum boat, but you may want to consider a more powerful option for improved speed and performance, especially if you plan to cover greater distances or carry multiple passengers.

A 28lb thrust motor is not powerful enough for a 16' aluminum boat

A 28-pound thrust trolling motor is unlikely to be powerful enough to effectively propel a 16-foot aluminum boat. While it may provide some movement, it will likely be insufficient for practical use, especially in windy or rough water conditions.

The general consensus among boaters is that a higher thrust motor is preferable, with a 45- to 55-pound thrust often recommended as a suitable minimum for a vessel of this size. This is based on the understanding that a more powerful motor provides better performance, longer battery life, and the ability to handle varying water conditions.

For example, a 30-pound thrust motor on a 16-foot aluminum boat might achieve a speed of 2.2 miles per hour with no wind, but this would deplete the battery in around 3 to 4 hours. In contrast, a more powerful motor would provide faster speeds and longer battery life, making it a more efficient and reliable choice.

Additionally, when considering a trolling motor, it is worth noting the benefits of electronic speed control (ESC). Unlike older variable speed controls, ESC uses a technique called rapid current chopping to achieve speed control, resulting in longer battery runtimes as it uses less current.

Therefore, when choosing a trolling motor for a 16-foot aluminum boat, it is advisable to opt for a higher thrust model, ideally with modern features like ESC, to ensure adequate performance and maneuverability on the water.

A 30lb thrust motor can achieve a speed of 2-3 mph

The speed of a trolling motor is determined by the prop pitch and motor RPM, not solely by the thrust of the motor. Thrust is simply a measurement of pushing or pulling power, and higher thrust does not always mean greater speed. That being said, it is important to have sufficient thrust to power your boat effectively. A good rule of thumb is to have at least 2 pounds of thrust for every 100 pounds of fully loaded boat weight. This ensures that your motor has enough power to move the boat and provides extra control in windy or current conditions.

For example, a 14' aluminum v-hull boat is likely to weigh around 2,000 pounds when fully loaded. Using the rule of thumb mentioned above, this boat would require a minimum of 40 pounds of thrust to function adequately. A 30lb thrust motor would be slightly underpowered for this size of the boat but could still achieve speeds of 2-3 mph in calm waters.

It is worth noting that trolling motors typically have a speed cap of around 5 mph, and if higher speeds are desired, an outboard motor would be necessary. Additionally, when considering a trolling motor, it is recommended to opt for one with electronic speed control (ESC) as it provides better efficiency and longer run times compared to the old-school variable speed controls.

A 36lb thrust motor is powerful enough for a 14' aluminum boat

A 36-pound thrust motor is a good option for a 14-foot aluminum boat. This size motor is typically recommended for boats between eight and 12 feet in length, so it will be powerful enough to move your 14-foot boat.

The right size motor for your boat depends on several factors, including the vessel's size and weight, the water conditions, and your intended use. If you plan to operate in strong currents or windy conditions, you may need more thrust to compensate. Additionally, if your boat has a deep draft, you may require more power to get it moving.

A 36-pound thrust motor should provide adequate propulsion for a 14-foot aluminum boat in calm waters. However, if you frequently encounter choppy waters or strong headwinds, you may benefit from a higher-thrust motor, such as a 45- or 55-pound model.

It's worth noting that a 36-pound thrust motor may not be ideal if you plan to use your boat for activities that require higher speeds, such as water skiing. In that case, you might consider a more powerful gas outboard motor.

When choosing a motor, it's important to consider your budget and the type of battery required. More powerful motors may offer longer run times on a single charge, but this also depends on the capacity of your battery. Additionally, keep in mind that electric trolling motors are typically designed for auxiliary propulsion rather than sustained, high-speed travel.

In summary, a 36-pound thrust motor should be sufficient for a 14-foot aluminum boat in calm waters, but you may want to opt for a higher-thrust model if you frequently encounter challenging water conditions or need to travel longer distances.

A 45lb thrust motor is powerful enough for a 12' aluminum boat

A 45-pound thrust motor is powerful enough to move a 12-foot aluminum boat. In fact, a 30-pound motor would be sufficient to power such a boat. A 45-pound thrust motor can be considered a good balance between power and performance, as it provides a minimal increase in performance without a significant increase in cost.

A 45-pound thrust motor can be used as the main source of power for a 12-foot aluminum boat, but it is important to consider the type of water and usage. For example, a 45-pound thrust motor may not be powerful enough for windy conditions or larger lakes. In such cases, a 50- to 55-pound thrust motor may be more suitable.

When using a 45-pound thrust motor, it is recommended to have a good battery to ensure optimal performance. Additionally, the type of motor mount can impact performance, with bow mounts being easier to control and steer than transom mounts.

It is worth noting that trolling motors are typically capped at 5 miles per hour, so an outboard motor may be necessary to achieve higher speeds. However, a 45-pound thrust motor can be a good option for quiet lake fishing and trolling.
