Where Is a Trolling Motor Mounted on Your boat?

Trolling motors can be mounted on the boat’s engine, transom, or bow depending on the type. There are 3 types of trolling motor mounts. Your motor can either be a bow mount, transom mount, or engine mount.


These trolling motors are great if you prefer fishing on the foredeck of your boat. They are straightforward to operate. This is because they enable you to steer the bow of your boat with precision. One of the advantages is that they have more sophisticated controls and features such as wireless steering and GPS.

However, they also feature some setbacks. They are a bit difficult to install compared to transom motors. It’s because they require a horizontal surface at the front of your boat to be fixed. Additionally, they are also relatively expensive.


These are less expensive and easy to install. Of course, this is what makes them popular among canoe, dinghy, and small boat owners. The motor is attached to the boat’s transom using dual clamps instead of one.


This model of trolling motors is remotely controlled and steered together with the outboard. It’s fixed to the cavitation plate of outboard motors. The good thing about it is that it requires less space.

How Do You Determine The Correct Thrust For Your Boat?

When buying a trolling motor, thrust is the most important thing to consider. It lets you know if the motor is powerful enough to push your boat at the right speed. Take note thrust is measured in pounds. It also gives you a rough idea about the motor’s performance. Note that you will need more thrust if your boat is heavy.

How to Calculate the Best Thrust for Your Boat

First of all, you need to know the exact weight of your boat. As a rule of thumb, for every 100 lbs. you will require at least 2 lbs. of thrust. For instance, if your boat’s weight is 5,000 lbs. when fully loaded, you will require 5,000/100 x 2 lbs. = 100 lbs. of thrust for your trolling motor.

How Do You Calculate Your Battery Runtime?

This depends on two things. The current draw of your trolling motor, which is measured in amperes, and the capacity of your battery which is measured in Ampere hours (Ah).

For example, if your battery has a 200 Ah capacity and the motor draws 40 amps of the current, then to find the run time is simple. You just need to divide 200/40 = 5 hours of run time.

Unfortunately, this is only a theoretical number. Various factors determine the exact duration the battery will last and you don’t want to deplete it to 0%. For instance, if you want to keep your battery in good shape, you should only use about 50 – 70% of its Ah capacity.

Which Is The Best Steering Option For Your Trolling Motor?

There are 3 different steering options for a trolling motor. They are:

  • Electric steer

This model features more control options such as GPS positioning and wireless remote. They help you get where you want and focus on fishing.

  • Cable steer

A multi-function foot pedal and motor are linked directly via a cable in these models. Compared to the other 2 versions it’s less sophisticated and more responsive. It’s popular, especially with bass fishermen.

  • Hand steer

For direct control, these motors use a tiller handle just like traditional outboards.

Do You Want a Trolling Motor With Saltwater Operation Capability?

Ensure that before you purchase any trolling motor you check whether it can be used in saltwater. Compared to freshwater, saltwater is much more corrosive and requires different materials.

For example, let’s take a look at Motorguide and Minn Kota saltwater motors. They are built with premium-grade alloys and then coated with Zinc. Finally, they are painted with corrosion-resistant polyester paint. They all feature a sacrificial anode fixed to the prop to ensure they last much longer.

That said, you should note that if a freshwater trolling motor is used in salty water, it will nullify your warranty.

Why Do You Need to be Keen on Motor Voltage?

When you compare 12V trolling motors with their 24V and 36V counterparts, they are the cheaper option. However, they offer less thrust. Higher voltage systems are more efficient and powerful. For instance, they have a lower current flowing through the cables at the same power output.

Another factor you need to consider is the number of batteries. If you are using a 12V trolling motor, you only need one 12V battery. You will need to connect 2 or 3 batteries in series for 24V and 36V systems. So, the more the number of batteries of the same size, the more the capacity and range available.

In most cases, trolling motors that have a thrust of 55 lbs. or less use 12V (single battery). Those with a thrust of 68 – 100 lbs. use 24V (2 batteries) while trolling motors with a thrust above 100 lbs. require 36V (3 batteries).

How Do You Calculate the Right Shaft Length?

Getting the right shaft length for your trolling motor is important. Regardless of the water and weather conditions, it must be long enough for the propeller to stay submerged at least 16” below the waterline.

In case the shaft is short, the propeller may get out of the water and suck in air. This causes loss of power, noise, and can shorten your motor’s life.

Which Are the Most Important Features?

We have highlighted a quick overview of the most vital features you’ll find on a trolling motor.

  • Variable Speed Controller

In both forward and reverse, a variable-speed motor has smooth power delivery. Motors with a variable speed controller draw less power, especially at lower speeds. This means that no energy is wasted. Therefore, you get more run time off your battery.

  • Autopilot

With an autopilot feature, your trolling motor can steer on its own in the set direction. To keep a steady heading it uses a compass. The feature can be used in many ways such as trolling along a shelf, ledge, or shoreline.

  • GPS Navigation

By pressing a button on the remote, GPS trolling motors enable you to steer, lock onto fishing spots, and control speed. It’s mostly found in premium models.

  • Fish Finder Integration

With high-end trolling motors, you can use the fish finder screen to control your steering and speed. To Spot-Lock, go to your fish finder’s waypoint. It automatically follows depth contours.

  • Sonars and Transducers

These feature inbuilt transducers for sending images to your fishfinder. They come fully integrated with the lower motor section meaning there are no additional connectors or cables involved.

  • Lift-Assist

To make stowing and deployment of motors easy, manufacturers use various designs of lift-assist. Some use a stainless steel gas spring while others use a spring-loaded mechanism. The good thing is they all make lifting your motor easier and safer.

  • Auto Stow and Deploy

This feature is found in a few premium models such as Minn Kota Ulterra. Ulterra offers a 100% automatic stow, deploy, and trim system instead of a lift-assist mechanism. It’s easy to use since the only thing you need to do is to press the foot pedal or a button on your remote.

Benefits of a Trolling Motor

There are numerous advantages of using a trolling motor on your boat. They include:

  • When using an electric trolling motor, you don’t have to carry oil and fuel
  • They are light and easy to install/remove
  • The use of a trolling motor in a rowboat makes work easy without using a lot of manual labor
  • Fishers can fish quietly by avoiding loud noises from the engine
  • The lake/river’s current or bad weather doesn’t have to worry you considering some models are designed to tackle such hurdles
  • With a trolling motor, your boat can move at a steady speed with precise control to prevent startling fish

Minn Kota Edge 45 Alternatives

If you didn’t find the Edge 45 to be a good option, check out the alternatives below. Fishermen or fishing fans who didn’t for it went for the options below.

Minn Kota Fortrex 80/112

Minn Kota Fortrex 112 Motor

Fortrex is a bow-mounted trolling motor with excellent performance. It has a simple and quality design available in 2 thrust options (80 lbs. or 112 lbs.) which draw on 24 and 36-volt batteries respectively.

For an appropriately sized boat and load, the 80 delivers plenty of thrust. Compared to the brawny 112, it does so with a more gradual ‘ramp-up’. Even though 112 lbs. delivers a wallop, if you fish in heavy wind zones it’s the best choice. What you need to do is to watch your footings as you engage the motor.

The composite shaft which helps deliver power is available in 2 different lengths (36” and 45”). Fortrex comes with Weedless Prop and Weedless Wedge 2. Rest assured you won’t strain to operate the motor as you fish because it’s controlled by a precise foot pedal.

The good thing with this model is that you won’t outfish it at low throttle positions. At the end of the day, the maximizer tech ensures you have battery power to spare. The motor also features a gas-filled piston and spring which cuts the felt weight in half when stowing or lowering into the water.

Minn Kota Fortrex is a fantastic option if you have a large boat and you are in the market shopping for a bow-mounted trolling motor.


  • Mount type: Bow
  • Shaft length: 36 and 45inch
  • Starting system: Electric
  • Thrust: 80 lbs. or 112 lbs.
