Trolling Motor Buyer’s Guide
Modern angling has at its disposal a motorized trolling kit called a trolling motor which allows for precise maneuvering of a boat when fishing.
This kit is basically a functional self-contained unit with its centerpiece being the trolling motor which guides and powers the operation of the entire unit; and for this reason it is called a trolling motor unit, or simply a trolling motor.

What is Trolling?
In trolling, a fishing line that is fitted with a series of baits, usually baiting fish or lures, is drawn across a water body (such as a dam, lake, slow-flowing river, or sea) by a boat.
This is a specialized modification of angling where the fisherman (angler) holds a fishing rod at whose end is attached a fishing line that holds a fishing hook.
The angler therefore has to steady the rod when baiting a fish, or guide the line and hook through the water to a spot where this a high concentration of fish (or a high probability of fish being baited easily).
Moreover, the angler needs to also steer the boat when angling thorough the water. However, this can be a tiring process if one is to do this for hours on end, for instance, 4 hours, which is the approximate period that fishing hobbyists take during each angling session.
To simplify this process, the precision steering mechanism of the boat is provided by a unit that contains a stationary cylindrical shaft that holds a propeller unit at one end, while the other end is its control arm which allows a person to spin it around so as to change the direction (or orientation) of the propeller unit.
The propeller unit drives the boat and the angler uses the control arm to steer it. If the propeller unit is driven by a motor, then this equipment is called a trolling motor.

The fishing rod can sometimes be fitted to the boat, on the other end is fixed the fishing line which contains the hooked bait.
If multiple baits are fitted to the line, then more fish can be caught at the same time. The rod and (fishing) line is now called a trolling line, and if it is dragged slowly through the water, then this form of fishing is described as trolling.
This can be upgraded to a commercial level if short fishing lines called snoods (or sometimes gangions) are attached to the main fishing line at set intervals (or distances) so as to create a highly branched fishing line.
The snood is the branch, and it contains multiple baited hooks. The use of this commercial-grade, highly-branched fishing line for angling is called longline fishing, and the highly-branched fishing line is called the longline.
As is evident, one can increase the (fish) catching capacity of trolling by branching the trolling line or by attaching multiple trolling lines to the boat.
If multiple trolling lines are used, then one needs to attach a special structure called an outrigger to the boat, and then use it to evenly spread the trolling lines across the water surface.

The Trolling Motor
Trolling can be accomplished if a trolling motor is attached to the boat. Even so, this unit does not do the fishing but serves as a means of allowing the angler to fist.
In fact, the primary function of this unit is to provide propulsion that is precise, highly-measured, and accurate so that the boat can be steered for a short distance to a new fishing spot.
Nonetheless, it is not designed to be used as the primary means of propulsion, but rather as the secondary means; as the outboard motor is the main propulsion system of the boat.
Its secondary function is to hold the boat in a stationary position so that one can cast the trolling line, or wait for fish to be caught.
There are also instances where powerful trolling motors have been used as the primary propulsion system, but this is not recommended because of the way it is fitted to the boat.
Basically, it can be fitted in one of three places; the bow, transom, or the stern of the boat.
On the other hand, the outboard motor is fitted outside the transom, and this location is ideal as it allows the motor to provide a pushing propulsive force that drives the boat forward.
Therefore, for the trolling motor to act as the main propulsion system, then it needs to be fitted outside the transom which is not recommended.
In fact, it is highly recommended that it is fitted at the bow of the bow so that it can provide a pulling force which allows for the boat to pull across the water surface, as pulling allows for better (steering/maneuvering) precision as compared to pushing the boat.
It is also for this reason that the trolling motor needs to be lifted from (that is, pulled out of) the water so that it does not create an unnecessary drag when the outboard motor is in operation.
The initial description of what later became the trolling motor was published by Scientific American in 1895; and in 1934, O.G.Schmidt built the first electric trolling motor in Fargo, which is a border city in North Dakota that neighbors Minnesota.
Consequently, the company that built this model was called Minn-Kota – a portmanteau that blends the state names of North Dakota and Minnesota.
To date, Minn Kota remains one of the leading manufacturers of trolling motor units.
How the Trolling Motor is Powered
Modern trolling motors can be broadly classified into 2 categories based on how their motors are powered, and these categories are gasoline-powered and electric-powered trolling motor.
In a gasoline-powered trolling motor, the motor is operated by a single-stroke petrol engine; and because the engine produces smoke, this motor unit is affixed at either the stern or behind the transom which ensures that the smoke does not choke the angler.
Also, because of this fitment position, the trolling motor can serve as a secondary outboard motor.
Moreover, the use of a fuel-powered engine necessitates the inclusion of gear controls, a throttle, and a manually-operated pull start system.
These components are usually contained in the motor encasement or are attached to the motor housing. Most models are steered using a tiller, though one can modify this when using it exclusively for trolling.
This is done by connecting the tiller steer to a more accessible steering mechanism located at the helm of the boat.
Most trolling motors in the market today are electric-powered models. In this model, the motor of the trolling motor unit is powered by direct current (DC) provided by a rechargeable battery – the trolling motor battery.
This battery is usually a deep-cycle battery, and its voltage ratings is using 12-volts or a multiple of 12- that is – 24-volts or 36-volts. Some smaller models can run on 6 volts, and these use either the 12-volt or the much smaller 6-volt batteries.
These deep-cycle batteries are specially designed for marine use, while the motor is uniquely designed to be compatible with these batteries, and this is the reason why a brushed commutated electric motors are used.
As mentioned, it the battery that powers the entire unit. The parts of this unit are described below.

Parts of an Electric Trolling Motor Unit
The unit can be divided into 3 functional parts; the head unit, the shaft, and the lower unit.
It contains the control system of the trolling motor. This is the system that controls boat steering, as well as regulates the speed of the motor. For this reason, the head unit is also called the control unit.
In hand-controlled trolling motors, the manual tiller handle extends from this head unit; while in foot-operated, a cable containing both the steering and electrical wires extends from this unit and terminates at the foot control pedal.
The length of this cable determines how far away the foot control pedal can be placed from the angler. There is also an electrical plug that extends from this control pedal that allows one to connect the head unit to a battery.
In hand-operated systems, the control knobs and motor speed control can be built into the tiller itself.
Also, the battery cables extend from the head unit and terminate onto crocodile clips that allow the unit to be connect to the battery terminals.
In foot-operated units, the on-off switch and motor speed control are built into the pedal, which also manages boat steering.
This requires the pedal to be secured stationary to the frame of the boat, and this is done using a mounting bracket that is bolted to the boat frame or body. in modern models, steering is controlled electronically via servo motors, while in earlier models, a push-pull cable was used.
Moreover, in high-quality, well-designed models; servo-controlled steering is managed remotely via a wireless remote, with the wireless device being placed in the foot pedal or in a specially-designed key-fob transmitter.
Models that come with a key-fob transmitter are completely wireless, and do not feature a wired foot pedal, nor do they have a manual tiller.
The shaft connects the head unit to the lower unit, in addition to housing and transmitting the connection cables.
In hand-controlled, it comes with a clamp that allows one to secure the trolling motor unit to the bow of the boat.
The most important feature of the shaft is its length. This is important as it determines how deep the lower unit can be submerged into the water.
Generally, it is advisable that the lower unit is at least a feet below the water surface, as any shallow level could cause the propeller blade to cavitate and would result in frequent yaws.
There are 3 important shaft length measurements; the length from the water to the lower unit, from the waterline (water surface) to the deck level, and the length from the deck level to the control unit (the above-deck shaft length).
The above-deck shaft length determines how high the head unit is. If the model is hand-operated, then the above-deck shaft length must be high enough so that one can operate the tiller comfortably.
This length can be reduced in foot-operated models, while remote-controlled models have the shortest above-deck shaft length.
This is the propulsion unit, and it houses both the motor and the propeller. The motor is encased in a water-tight compartment as it needs to be fully submerged during operation so that heat dissipation can occur efficiently.
The shaft is attached to this motor encasement. On the other hand, the propeller shaft that holds the propeller blades slightly protrudes from the motor encasement. This allows the propeller blades to be located outside the motor unit.
The lower portion of the motor encasement is usually extended downwards to form a skeg that serves as the steering fin of the lower unit.
Additionally, in foot-controlled and wireless models, the motor unit features a mount that allows one to secure the lower unit to the boat hull.
Some of the models come with a hinged mount that allows for easy stowing of the lower unit, especially when it is not being used.
The propeller unit is made up of the propeller shaft that is connected to the motor hub, and the propeller blades, usually 2 or 3 in number.
The propeller shaft allows for the propeller blades to be rotated so as to generate the propulsive force.
Types of Trolling Motors
Trolling motors can be categorized into different types based on their structural and operational designs, as well as the control system used.
Based on Operational Design
Trolling motors can be categorized based on their operational environments into 2 types; saltwater models and freshwater models.
Salty water models have their components built of corrosive-resistant materials, with the main materials used being stainless steel and composite materials.
The reason for this is that salty water quickly oxides metal components, hence speeding up the process of corrosion.
Therefore, saltwater models must be able to withstand corrosion better than models built for fresh-water operation.
This also means that one cannot use a fresh-water model as a substitute for a salty-water model, but a salty water model can be safely used as a substitute for a fresh-water model.
Based on Structural Design
The troll motor unit can be classified into 3 types based on their structural designs which also determines where they would be mounted on the boat. These 3 types are the transom-mount, bow-mount, and stern-mount trolling motors.
Based on Control System
This allows for the classification of trolling motor units into 3 types as the control system can be a hand-control, a foot-control using the foot pedal, and wireless control which is controlled using a remote.
Hand-control or tiller-style models are the cheapest of the three, and they also have the least number of parts which means minimal maintenance.
It also the most responsive and can allow one to quickly change the boat direction in emergency situations (shortest response time).
This makes it ideal for trolling in water bodies that have lots of obstacles such as floating logs and rocks which one must avoid frequently.
Even so, it suffers from one critical demerit which is it takes the hands off the fishing gear, and this can make trolling a little bit uncomfortable.
To solve this issue, a foot pedal was introduced for controlling the trolling motor. This allows for easier and faster steering, but the response time is slightly lengthened.
Also, it can be challenging for one to seamlessly coordinate the hand and feet movements during trolling. Usually, foot-operated models are mounted to the bow, and this requires one o be at the bow when fishing.
Sometimes, one wants to enjoy fishing from any place on the boat deck. In this instance, one needs to install the wireless model as a remote control allows one to operate the unit from anywhere on the boat. Even so, it suffers from slower response times compared to tiller-style models.
This determine the trolling motor battery that needs to be used with the trolling motor unit. There are voltage configurations for trolling motors; the 12-volt, the 24-volt, and the 36-volt models.
The voltage ratings of the trolling motor also determine its power output, with those with higher rating being able to produce more usable power as compared to models with lower voltage ratings.
This means that a 36-volt model with a power rating of 100 pounds-of-thrust is much more powerful than a 12-volt model with 80 pounds-of-thrust.
The trolling motor operates to move the boat, and this means that it should generate enough power to propel a loaded boat.
This also means you need to understand what thrust capacity trolling motor you need for your size boat.
Expectedly, it is better to rate its power in terms of how much thrust it can generate. Thrust is the reaction force that accelerates the mass of the boat.
It is described as a reaction force because it is generated when the motor unit drives the propeller blades to push the water current backward so that the boat propels forward.
As a force, its unit of measurement in Newton (N); and because it considers the boat mass; it is clear that different boat sizes would require different levels of thrust.
Usually, the power of the trolling motor is rated in pounds of thrust, which allows one to relate the boat weight to the amount of thrust required.
As a general rule, for every 50 pounds of boat weight, a thrust of a pound is required.
This means that one should purchase a trolling motor whose pounds of thrust exceed 50 pounds, as one must consider wind and water currents which add the thrust requirement.
Thrust can also be related to power consumption from the rechargeable battery. The general rule is that 75pounds of thrust is approximately 1 horsepower or 746 watts of electric power.
Because trolling motor batteries are rated in terms of Amperes-hours (Ah), one can determine the power draw.
This allows one to calculate the battery requirement, and in extension the voltage rating of the trolling motor to be used. For example to generate 75pounds of thrust to fish for an hour on a 24-volt battery, one needs:
746 watts = (Battery Capacity X 24) / 1 = 31.1 Ah.
If a 12-volt battery is used instead, it should have a capacity of 62.2 Ah.
Also, because most 12-volt batteries can comfortably support a trolling motor unit that develops 55 pounds-of-thrust, it is advisable that one acquires a 24-volt deep-cycle battery, and this means that one must choose a 24-volt DC trolling motor unit.
The general rule with regards to battery rating and thrust generated is that 12-volt batteries can support a trolling motor system that generates 55 pounds of thrust, while 24-volt batteries can support a system that develops approximately 80 pounds of thrust, and the much larger 36-volt batteries can support a system capable of generating 105 pounds of thrust.
Thrust and Trolling Speed
It is also important to mention that thrust does not affect the speed of the trolling unit. This means that 100pounds of thrust generated by a trolling motor with a maximum speed rating of 5miles-per-hour (5mph), allows the boat to achieve a maximum trolling speed of 5mph.
40pounds of thrust developed by another trolling motor of equal speed rating also allows the boat to achieve a maximum trolling speed of 5mph.
This shows that trolling speed is a function of the trolling motor, as it is the motor that propels the propeller blades that determines how fast the boat can move.
Global Positioning System (GPS)
In modern, high-quality trolling motor models, GPS is integrated into the wireless control system in the head unit. As expected, GPS can only be integrated with foot-controlled or wireless models as these are the only rolling motors types that can support wireless technology.
The key advantage of GPS is that it allows one to train the trolling motor to map the shoreline and the mapped area is stored in the control unit.
This allows the GPS transducers to operate the servo motors so as steady the boat on a fixed course. Depending on the quality and reliability of the GPS installed, and its integration to the control system of the trolling motor, the GPS can effectively maneuver the boat in an autopilot mode.
Likewise, it can come with a GPS lock which can keep the boat stationary at a particular place.
How to Choose the Right Trolling Motor
The first factor that one considers before purchasing a trolling motor unit is the fishing environment, that is, will fishing be done in salty or fresh water.
This allows one to choose between saltwater and fresh-water models.
Next, one must consider the mount location on the boat. Bow-mount models are usually recommended as pulling the boat allows one to precisely set the course, which allows for short bouts of precise movement that does not startle the fish and cause them to disperse from the desired fishing spot.
Thereafter, one must consider the boat weight so as to determine the required pounds of thrust. Afterward, one chooses the control system that best suits him/her. The control system also determines the voltage rating of the trolling motor unit to be used. After this, one can look at the trolling speed.
The aforementioned factors allow one to determine the best trolling motor type for his/her fishing needs.
