Saltwater Electric Trolling Motors

trolling motor saltwater

Over the past decade, saltwater electric trolling motors have become common, even practically standard on small inshore boats. Now trolling motors are available even for large offshore fishing boats.

A trolling motor is a small electric motor used to maneuver the boat while fishing. Unlike the large gas motor, a trolling motor gives you less noise and more maneuverability. The new generation of saltwater trolling motors is connected to GPS to accurately locate the boat and anchor it in the desired spot.

Also, it’s important to choose a high-quality trolling motor made with advanced corrosion protection.

In this article, we’re breaking down some of the most important saltwater trolling motor characteristics and trolls motor brands – all to help you find the best pick and enjoy hours of wonderful fishing experience.

Best Choice For Fishing

Fishing is an activity that requires incredible patience, attentiveness and impressive physical training. When fishing on a boat, one must choose the best gear, monitor depth, and always be ready to adjust the course. That’s where trolling motors come in handy!

Electric saltwater trolling motors are designed to provide a slow, steady push. They are typically mounted on the bow of a fishing boat and serve as support motors. Trolling motor is lightweight, compact, and relatively quiet, allowing you to get close to the desired area without scaring away the fish.

Trolling Motors for Saltwater

Trolling motors first hit the scene as auxiliary motors for anglers in 1980 and have rapidly evolved ever since. Trolling motors enable fishers to probe a shoreline methodically and quietly. Being bow mount, trolling motors are battery-powered and operated by remote control.

Trolls are ideal for boating hunts, where staying quiet is vital. Usually, electric trolling motor weighs under 10 pounds, making them exceptionally easy to transport and set up.

Saltwater trolls, except for their more robust lower-end models, typically have more powerful engines than their freshwater counterparts and larger propellers to give you the speed and torque you need to tackle harsh conditions. Naturally, these features come at a higher price than their freshwater counterparts.

Saltwater Trolling Motor Power

Trolling motors are pretty small and don’t offer any outstanding power. These motors’ power mostly peaks at 3hp.

To find the horsepower of an electric saltwater trolling motor, it’s also important to know how many watts it uses at its fastest speed. Most manufacturers provide you with the amps a motor uses at full swiftness.

Of course, not all manufacturers indicate the data necessary for calculations, but if you ever begin to count, take 746 Watts (1 HP) as a basis. When you find out the amount of Watts your trolling motor produces, divide it by 746, and you will get your motor’s estimated amount of HP.

There is a different way of calculation, but if you need the exact number, we recommend using the previous one. You can take into consideration the fixed amount of lbs per Hp (55lb = 0.84hp) and make it simple:

0.84/55 = 0,0153hp per 1lb. Then take, for example, 110 pounds of thrust and do next: 0,0153 * 110 = 1.68hp. That method works if you need to get the approximate hp number, but it might show a little differently if you take the measurements precisely.

The most potent and reliable saltwater trolling motors are:

  • Minn Kota Fortrex with 80 inches shaft length/112 lbs

  • Minn Kota Riptide Ulterra with 72 inches shaft length/12 lbs

  • MotorGuide Xi3 Saltwater with 36 inches shaft length/55 lbs (best for kayaks)


One of the main advantages of trolling with an outboard motor is that it is much easier to keep the boat steady while fishing. The 110-pound thrust motor can handle boats up to 5,000 pounds.

Some trolls allow you to hold the boat on a specific heading while using the autopilot. I-Pilot link allows the trolling motor to communicate with Humminbird GPS and sonar. The Spot Lock feature is a good tool when bottom fishing for blackfish, scup, and sea bass. Increasing and decreasing the drift speed will drastically impact the behaviour of your bait or lure.


Fishing is becoming more than just a weekend getaway but a fast-paced sport constantly developing solutions for a more exciting experience.

Minn Kota trolling motors offer this experience and make it quite intriguing. For example, the I-Pilot system used by Minn Kota’s new saltwater trolling motors allows anglers to forget about constant route adjustments and make the process automatic.

The I-Pilot system is found on all of the new Minn Kota saltwater motors and is so advanced that it can guide you along predetermined routes or hold your boat in place while you are out fishing. The system offers Bluetooth control capabilities, and you can link the motor control even to your smartphone and set the boat route from the comfort of your seat using GPS!

If you still feel thirsty, check out the I-Pilot link, with the possibility of binding Fishfinder, which allows you to push all the boundaries and control the entire process from your smartphone. Change the route, follow the old way, look for fish spots or lock the boat in the area you like, and all that via wireless connection with your phone app.

Preventing Saltwater Trolling Motors Issues

An electric freshwater motor is not much different from one for salt water. Except the salt accelerates the wear of parts and provokes corrosion, and to prevent decay from salt or moisture and make the motor more convenient, wear resistance to corrosive effects is laid in these motors’ designs. 

You’ll need approximately 36 volts of electricity to power a heavy-duty mount trolling motor. We offer one of the best trolling motor Lithium batteries on the market today. Before buying a trolling motor for saltwater, think about a place to store the batteries and rigging the wires.

Trolling Motors we Trust

Trust, power consumption, and shaft length are important, but a trolling motor is worthless if it doesn’t work. The trolling motor has to endure rain, waves, and rough use. Once the trolling motor is in the water, you should have a reliable operation – controlling the direction, speed and functions without looking at the remote. Saltwater trolling motors make fishing easier with programmable routes, autopilot, and virtual anchors.

Many trolling motors exist on the market, but if you’re looking for reliability, efficiency, and practicality, we recommend motor brands such as ThrustMe, TEMO, RIM and ePropulsion.
