What size trolling motor do you need for your kayak?

In order to go faster and be more effective when skipping channels, a kayaker should always remember that they need more powerful propellers than those that are less powerful.

Even if you don’t need it right now, having extra power in an emergency is ideal. Having some spare power on hand is always a good idea in case of an emergency.

For every 400 pounds of weight, your motor needs to produce at least 5 pounds of thrust. But you will need a lot more than that for your kayak to glide through the water smoothly. 
The motor should supply at least 40 pounds of thrust. 

Because of their compact scale, small to medium-sized kayaks must be able to carry between 40 and 100 pounds of weight. 

If you want to paddle your medium kayak, you’ll need at least 30 pounds of horsepower or 46 pounds of horsepower, depending on whether you’re paddling in a lake or a river.

If you plan to travel through swift currents, a kayak with a trolling motor capable of generating 55 pounds of thrust and a knuckle shaft could be a good investment.

It’s not enough to have a powerful motor; you still need the energy to control it. The more powerful the motor, the more power is needed to power it, resulting in a longer battery life.


When deciding the amount of thrust required, it’s necessary to consider the boat’s weight as well as the number of pounds of thrust required.

One of the most important things to consider when deciding how much horsepower you’ll need is the weight of the ships.

The extra power you’ll need when paddling with factors like wind and current playing a part in your paddling will be greatly appreciated in the future.

As an illustration,

When a 12V motor draws one amp of current while running at 72 to 75lb of thrust, it consumes about 720W of electrical power.

That’s around one horsepower or 746 watts of electricity.

In a nutshell, power can be explained using the equation below: we can assume that higher voltage equals higher thrust, and vice versa.

Some of the most efficient trolling motors on the market have a thrust of over 100 pounds, making them capable of towing large vessels like pontoons.

Trolling motors come in a number of voltages, including 12V, 12/24V, 24V, and 36V.

The maximum thrust at different voltage levels is approximately 12V/55lb, while the maximum thrust at 24V/80lb is approximately 80lb.

The Right Size

Almost always, larger can be better. The larger the boat, the more energy it will consume, but we recommend you keep in mind the effects of tide, wind, and current on the boat when choosing a trolling motor.There is a good argument to be made for choosing the motor that is a little stronger than it needs to be.The lower speeds mean that the engine produces more power, covering more distance, at the same time as the safety margin increases to withstand the effects of the winds and waves.

It would take a trolling motor with a thrust of 5 pounds per 200 pounds of gross weight of the boat to operate.The best solution in this situation is to purchase a trolling motor with a low rpm limit, as it seems to be a safer proposition.

Motor Voltage vs. Battery Power

The larger and more powerful the motor becomes, the larger and more powerful the batteries must be to fuel it.

When purchasing a trolling motor, it is necessary to consider the battery’s capacity, which is one of the factors to consider.

It’s also worth noting that in order to use your trolling motor, it needs to be connected to a deep cycle battery, as a battery that isn’t compatible with a trolling motor will not work properly.

On kayak trolling motors, there are three different types of motors available, each with a different voltage.

The voltages of this equipment are twelve, twenty-four, and thirty-six volts.

Electric trolling motors typically operate at 12 or 24 volts, which makes them more popular among kayakers.

A high voltage trolling motor is likely to drain your battery more quickly and short the battery sooner than expected.

To feed your trolling motor’s voracious appetite, it is suggested that you have a lot of deep cycle batteries ready to go.

If you wish to use a 12 Volt one, I recommend that you do so. This is because it does not require as much electrical energy to work. It is, in my view, a very powerful and low-energy system.

Power Consumption

Imagine that you have nearly the same space in your boat as myself.In order to ensure that you will be able to install the batteries you need in order to handle the energy demands of a trolling motor safely, please check the following .FurthermoreI need to know in advance whether or not you will be able to charge the batteries while on the move.

It is important that you choose the best models that can handle the amp draw that you demand and make that determination before you purchase them.12V model with a 54lb thrust and 24V model with a 44lb thrust can use 28A of current with a 24V model, but a 36V model with 48lb can use 48A of current. thrust can draw 42AThere is a general rule that larger motors require more power and a larger battery to facilitate full power control.For those who intend on employing their vessel year round, especially if that vessel is a 16 footer, it is advisable that they arrange for a dock.You should use a minimum of 24VA motor and a very experienced kayaker who spends a lot of time on the water might benefit from a 36V motor.

Battery storage space

In case you are going to use a boat, you need to make sure that it has sufficient storage for the trolling system.

The most important thing to keep in mind is that you will need a lot of space for your 31 lb thrust system in addition to the 3 batteries (36 voltage system).

Until recently, the only kayak brand offering motor mounts was PaddleSki. All of our Sea Eagle kayaks have been upgraded to include motor mounts. Therefore, let’s look at some environmentally friendly and cost-effective power options for Sea Eagle inflatable kayaks and fishing boats.

What is my maximum speed?

The thrust rating of an electric motor is used to select it for trolling. Additional thrust will not accelerate the boat. Indeed, two motors with a combined thrust of 55 pounds will be slower than a single motor with a combined thrust of 30 pounds. Larger, heavier boats and heavier loads require more thrust from 12-volt trolling motors. A trolling motor’s top speed, regardless of thrust, is 5 miles per hour. A MinnKota Endura equipped with 55# thrust and all the latest electronic gadgets is completely useless. Money-saving tip: Choose the MinnKota 30# Endura if you want to save money on a high-performance trolling motor.

Is there any limit to how far I can travel?

MinnKota’s twist knob speed regulator features a forward travel range of five gears. The top of the MinnKota Endura motor features markers that serve as a reference chart for the number of hours your boat can run at speeds ranging from 1 to 5. The battery lasts two hours at continuous top speed (5 mph), four hours at top speed, three hours at top speed, two hours at top speed, two hours at top speed, and two hours at top speed, and one hour at minimum speed. I’ve discovered that with careful use, if I don’t charge it, I can enjoy weekends on the water.

Consider the following when selecting a trolling machine:

Propulsion systems for the bow Bow thrusters are advantageous if you fish primarily from the boat’s open bow or from the boat’s front deck. Spring mounts, such as Minn Kota’s BowGuard 360, allow the engine to deflect on impact, preventing damage from grounding. Trolling motors are frequently used as stern-mounted, rudder-driven auxiliary engines on very small boats and light sailboats.

Carrier motors feature adjustable brackets that allow for the motor shaft to sink to the desired depth.

Water that is both fresh and salt

Saltwater motors are corrosion-resistant and feature improved mechanical and electrical component sealing.

Length of shaft

A 42-inch shaft is considered standard. Measure the distance between the deck or stern shaft and the water’s surface to determine the proper length for your boat. Then subtract 16″ (MotorGuide) or 20″ (Minn Kota) and choose the most accurate measurement. We recommend a longer shaft for rough water operation so that the propeller is approximately six inches below the surface when the boat gains altitude and lurches. Utilize the adjuster on the bracket to fine-tune the motor’s vertical position.

Size Appropriately

Almost always, larger is preferred. While larger boats require more horsepower, we recommend taking swell, wind, and current into account when selecting a tug. Preferring the more powerful side has a number of advantages, including the fact that a more powerful engine operates more efficiently at lower speeds and provides a safety cushion in the event of wind, waves, and currents. 5 pounds per 200 pounds total boat weight is the recommended draft.

Consumption of electrical energy

Consider the size of your boat, the amount of battery capacity that can be installed safely to meet the trolling motor’s power requirements, and your ability to charge the batteries while driving. Determine the model’s wattage requirements. A 24-volt model with a 54-pound pull may draw as little as 28 amps, whereas a 12-volt model with a 44-pound pull may draw as much as 36 amps. More powerful motors, in general, require a larger battery capacity. 24 volts may be required if you’re fishing from dawn to dusk in a 16-foot or larger boat. Serious anglers who spend significant time on the water will opt for a 36-volt motor.

For trolling motors, there are a variety of cable sizes available.

Calculating the cable size for a trolling motor can be challenging, particularly if you are unfamiliar with the various technical terms and calculations. It is a little easier, however, if you know the motor’s voltage and current.

Measurement of the Wire

The term “wire gauge” or “AWG” (American Wire Gauge) refers to the cross-sectional area of a round wire, which is proportional to the area of a round millimeter. A circular millimeter is equal to its diameter, and the cross-sectional area of a wire is equal to its diameter squared (round millimeter area).

The AWG number decreases in size when the wire is larger or thicker. When choosing a cable, the longer the cable, the smaller the AWG number required, as the cable must be sufficiently strong to compensate for the increased length.


Amperage refers to the amount of power or current drawn from the battery by a traction motor. You can determine the size of the breaker required for your system based on the amperage of the motor.

Calculate the amperage by calculating the draw of your trolling motor. This value can be calculated by dividing thrust by voltage and multiplying by twelve.


The voltage at which your trolling motor operates frequently dictates the cross sectional area of the conductor and the type of breaker used. The majority of trolling kayak motors operate on twelve or twenty-four volts. If the motor is 12-volt, a 12-volt battery will be required. Two 12-volt batteries are required if the motor is 24 volts.

Voltage is a term that refers to the current flowing from the battery to the motor. Because the current flows in a straight line from the battery to the motor, it is frequently called direct current (DC). This is not the same as the alternating current (AC) that we receive from our home’s outlets.

Breaker Circuit

Circuit breakers safeguard against overcurrent damage to circuits. When the current becomes too great, the circuit breaker cuts the power off.

The United States Coast Guard requires that all ungrounded live conductors be protected by a circuit breaker or fuse, which means that many trolling motors require a circuit breaker.

By and large, your circuit breaker should be rated higher than the motor to ensure that it can adequately handle the current flowing through it.

A 50 or 60 amp circuit breaker, depending on the amperage and voltage of the motor, is required for the majority of trolling kayak motors.

Which wire gauge is best for 12-volt and 24-volt trolling motor batteries?

Numerous trolling motors are compatible with 8-gauge wire, but the length of wire required and the motor’s current may dictate the wire size required. For instance, if a longer wire is required, a smaller gauge and thus a thicker wire may be required.

The tractor manufacturer should be able to advise you on the optimal AWG size for your tractor. However, we have compiled current ratings for popular kayak motors to help you determine the size of wire to use and the recommended switch size based on the length required.

Why should I retrofit my kayak with a trolling motor?

A trolling motor is a self-contained mechanical device that is used to propel a canoe. It is purpose-built for fishing and maintains a constant speed and direction by drawing bait behind the boat (trolling).

However, we may be ahead of ourselves. What is a trolling motor, and why does your kayak require one?

There are two primary reasons to outfit your canoe with a trolling motor.

You want your canoe to resemble a boat so that it can be used for cruising, transporting passengers and gear, and generally zipping around the water.

Alternatively, you could equip your canoe with a trolling motor and fish.

Trolling entails continuously moving the canoe with the bait behind the boat, at a specific depth below the surface, and at a specified speed. This is done to fool the fish into believing the bait is floating prey and to encourage them to pursue and take it.

Now you can transport your canoe in the traditional manner – by paddling continuously. While the first 30 minutes are enjoyable, if you intend to pull the canoe for an extended period of time, a trolling motor is a much more comfortable and stress-free option.

Equipping your canoe with a trolling motor makes getting started simple.

Increase your catch – Fishing is a time-consuming endeavor. You can fish longer if you attach a trolling motor to your canoe.

Less paddling – Using a trolling motor on a canoe eliminates the need to paddle and exhaust your arms before catching a fish.

Additional reasons to outfit your canoe with a trolling motor.

Maintains the stability of your canoe in high winds, on rivers, and during tides.

Trolling motors powered by electricity vs. trolling motors powered by gasoline

When it comes to trolling motors for canoes, you have two options: gas or electric. Each has its own set of advantages, and ultimately, the best trolling motor for your canoe will likely come down to personal preference.

There are, however, several significant advantages to consider when installing a gas or electric trolling motor on your canoe.

Electrified trolling motors have a number of advantages.

We traditional canoeists are constantly inquiring about the benefits of electric trolling motors. Indeed, contemporary electric trolling motors offer a slew of significant benefits.

Electric trolling motors are quiet – they propel your canoe across the water almost as quietly as paddling. I have not asked any fish, but some anglers swear that electric motors do not scare fish away in the same way that gasoline engines do (although literally hundreds of thousands, if not millions, of fish have been caught on gasoline trolling motors, so ……).

Electric trolling motors are powerful – Modern electric trolling motors are available in 12 volt, 12 volt/24 volt, and 36 volt configurations, which provides enough thrust to propel even the heaviest canoes through the water.

Electric trolling motors are lighter – Electric trolling motors are relatively lightweight in comparison to gasoline outboard canoe motors. (The heaviest item is a battery.)

There are several distinctions between gasoline and electric trolling motors.

We’ll go into greater detail below, but here are some critical distinctions between gas and electric trolling canoe motors to consider before making a purchase.

Fuel – An electric canoe motor is powered by an electric charge stored in one or more series-connected 12-volt batteries, whereas a gas canoe motor is powered by the combustion of refined liquefied petroleum gas.

Units of Measurement – The thrust generated by an electric canoe motor is expressed in pounds (lb). In comparison, gasoline engines are classified according to their horsepower output (hp). This should provide some context for how long gas engines have been available.

Weight – Electric tugs are relatively lightweight, whereas gas engines are quite large. A 12-volt battery weighs approximately 30 to 50 pounds, while a 5-gallon gas trolling motor tank weighs approximately 35 pounds. As a result, the fuel maintains its original weight. As a result, the electric canoe motor has a weight advantage.

Gliding across the calm surface of a mountain lake in a canoe is just as zen as fishing.

The primary consideration should be the price. In summary, gasoline trolling machines are significantly more expensive than the most popular electric trolling machines. This equates to a four- to fivefold increase in cost.

Environmental stewardship – This is a concern that applies to each of these products. In North America, an increasing number of lakes allow only electric motors and prohibit gas-powered canoes. You have two options in this case: either avoid the lake altogether or invest in an electric trolling motor for your canoe.

What should my trolling motor do?

For more information, click on the image. Prior to selecting a trolling motor, determine what it should accomplish for you. While fishing, the majority of people simply want to slowly troll the lake.

This is also applicable to trolling motors.

Assist the boat in adjusting to its new level or glide through the water with the bow raised. This enables you to glide effortlessly through the water.

If you have a GPS-enabled trolling motor, it should be able to locate and maintain a fishing spot without difficulty.

This enables you to proceed directly ahead without deviating or deviating from your intended path.

A quick summary


It is important to take into consideration the trolling motor thrust of your boat when choosing a trolling motor.

One general rule to calculate a boat’s thrust is the following: if a boat weighs as much as 100 pounds, including its fuel and gear, it should be propelled using about two pounds of thrust.

As an example: a boat weighing 2000 pounds has thrust equal to (2,000 pounds / 100) x 2 = 40 pounds (at least).

When it comes to the trolling motor thrust, we believe that a higher power would produce better results than a motor with too little thrust.


An indicator of the power required for your trolling motor.For your trolling motor to run, you must have a minimum of one 12 volt battery.An additional battery could exert a considerable amount of pressure on the rotor, which could lead to less than sufficient wind support to maintain the machine at an optimum speed.

A device that could provide a thrust greater than 55 pounds at any time (one battery) is not available at the moment.

In order to meet the requirement of providing between 68-80 pounds of thrust (two batteries), a high amount of power is required.

When the thrust of the airplane is higher than 112 pounds, it should be powered by its batteries rather than by the engine alone.


Can you put a trolling motor on a kayak?

It is true that a trolling motor can be used in a kayak.

A set of trolling motor mounts will allow you to screw a trolling motor onto your kayak without having to spend too much time or effort on it.It has been reported that a professional mount is typically heavier and has a longer neck,This is why they are more expensive than those you can make at home.Even so, they look a whole lot better than homemade mounts.In addition, they are also much more durable and easy to maneuver.

The trolling motor should be properly connected to the boat so it is simple to steer the boat so long as the trolling motor is correctly installed on the vessel.

How fast will a kayak go with a trolling motor?

The maximum speed you can attain with a trolling motor is 5 mph.

Having the right electric trolling motor for a boat isn’t affected by how much horsepower it has, so it’s best to choose a trolling motor based on thrust, not horsepower.

You will never be able to move as fast as a motor that is propelled by two motors with 65 pounds of thrust as a single motor with 30 pounds of thrust.As a general rule, 12V motors with a larger thrust rating are designed for larger boats that carry a heavier load.

An individual trolling motor can only reach a maximum speed of 5 miles per hour, regardless of the amount of thrust it produces.

How big of a boat can a trolling motor push?

There are several factors to consider when choosing a trolling motor, and the weight of the boat can be a deciding factor for the type of trolling motor needed.

If possible, it is desirable to aim for a minimum of two pounds of thrust (i.e. how much propellant we feel) for each hundred pounds of weight.

In order to optimize the performance of your trolling motor for a given vessel, making sure you know how much thrust is required on your trolling motor is essential.As an example, you can find that the weight of the boat at full load is 3000 pounds.This is why the following equation is used: (3000/100) * 2 = 60 lbs of thrust.

When calculating the weight of the boat, take into account the heaviest possible weight, including that of the boat if it is fully loaded with all the passengers, gear, fuel, and a full tank of fuel.

How deep should a trolling motor be in the water?

This has been a hard-and-fast rule for years, and the top of the engine should be buried about one foot below the water’s surface.

As a general rule, the matter of choosing the motor shaft length is more critical for bow-mount motors than for transom-mount motors, because the motor will be closer to the water or deeper in the transom-mount location.

It is true that there is a considerable variation in shaft lengths between bow-mounted motors and conventional motors. This variable length makes bow-mounted motors more flexible than conventional motors.You must determine the distance between the waterline of the trailer or the transom and the surface of the boat’s transom or bow.In rough water, the measurement of the waterline should be 15 inches (38 cm) higher than the average.An excellent rule of thumb is to add 12” to the waterline measurement of the motor in order to be able to steer it while standing.

In order to prevent the propeller from sputtering from afar, it is important to safely bury the motor at the appropriate depth; this depth varies depending on the amount of wave produced by the propeller.

When you set the motor too deep, you run the greater risk of hitting things, picking up dirt, fouling the prop on weeds, and then taking a beating to the prop and/or shaft, all which will affect its performance.

Which is the lightest trolling motor for a kayak?

While the kayak is small in size, the device weighs only four pounds due to its slim design. It weighs 85 pounds, making it the ideal kayak weight.

Although it is a small bike even though it is not very heavy, it still has the muscle that is hard to beat along with the freedom to move forward and reverse as well as giving you a very smooth and effortless ride.

Watersnake’s ASP trolling motors T-18 and T-24 can be purchased as transom mounted trolling motors, but they can also be purchased with a kayak bracket.In addition to being very straightforward in its design, the motor is also very easy to maintain.As a result, these motors are very reliable and very easy to maintain.

Even though this is the case, there’s only a couple of speeds that you can choose from, which makes it a bit inconvenient.

In the recommendation to you, I would suggest that you keep your boats as light as possible. This is particularly recommended if you intend to use a very light trolling motor.

The weight of the baggage and the cargo can make life difficult, but it is important to get the shortest weight option in terms of battery size and weight, since a variety of battery options are available.

Can you run a trolling motor out of water?

In the case of a motor, the water outside of it helps to cool it down.It is unclear to me whether it is okay to run the motor for a short period of time.It may well be that over time, running the motor out of water without any load on it for a long period of time would seriously damage the battery.

In order to protect your trolling motors from overheating it is imperative that you insure them by immersing them while that motor is running. Motors and bearings should be immersed in water during operation.

Not going to expose our expensive trolling motor to damage just to be able to drain the battery for a few minutes just to be able to do that.

Although it is possible for the batteries to drain by using them on a power tool (not trolling motors) or by using one out of water, it is recommended to connect them to a power tool instead of using a trolling motor.
