Who Needs a Saltwater Trolling Motor?

If you frequently fish in saltwater, or if you want the option to do so, then a saltwater trolling motor is a wise investment. Even if you don’t fish in saltwater regularly, a trolling motor designed for saltwater use will be more durable and last longer than one that isn’t.

There are several things to consider when choosing a trolling motor for saltwater use. The most important is the motor’s thrust, a measure of power. The higher the thrust, the heavier the boat it can move.

Another important consideration is the trolling motor’s shaft length. In general, longer shafts are better for saltwater use because they give the motor more power and are less likely to bend or break.

Finally, you’ll want to ensure that the trolling motor you choose is corrosion-resistant. This is especially important if you plan on fishing in saltwater regularly.

With those considerations in mind, here are the top trolling motors for saltwater available in 2022:

Minn Kota Riptide Ulterra

BEST OVERALL TROLLING MOTOR FOR SALTWATER

SPECIFICATIONS

Style: Bow Mount   Thrust: 80 lb (24v), 112 lb (36v)   Shaft length: 45″, 60″, 72″   Steering: Electric-steer   Wireless Remote: YES   Speeds: Variable   Use in: Saltwater

TODAY’S BEST DEALS

REASONS TO BUY

  • Auto stow, deploy, and power trim
  • i-Pilot remote with Spot-Lock
  • Humminbird fish finder integration

REASONS TO AVOID

  • Manual stow can be problematic when the motor loses power
  • Electric-steer only

The Minn Kota Riptide Ulterra is our top pick for the best saltwater trolling motor in 2022.

The Ulterra is best known for its auto deploy, stow, and power trim. The auto stow/deploy on the Ulterra is very convenient for saltwater anglers, especially when solo fishing.

You can steer it with a foot pedal or the i-Pilot remote control. Minn Kota’s Spot-Lock (GPS anchor mode) is reliable in most conditions.

“I have had my Bluetooth Ulterra for over a year now, and the spot lock willl hold me on a dime. The auto deploy has been perfect for me.”

[The Hull Truth]

The main downside of the Ulterra is that when the motor loses power for some reason, it can’t be stowed automatically. You then need to go through a manual stow procedure.

By the way, Jacob Wheeler, the former Major League Fishing’s World Champion, recently upgraded to the Ulterra. (YouTube)




Garmin Force

BEST GPS ANCHOR TROLLING MOTOR FOR SALTWATER

SPECIFICATIONS

Style: Bow Mount   Thrust: 120 lb (36v)   Shaft length: 50″, 57″   Steering: Electric-steer   Wireless Remote: YES   Speeds: Variable   Use in: Saltwater

TODAY’S BEST DEALS

REASONS TO BUY

  • A powerful combination with a Garmin GPS fish finder
  • Brushless motor runs on 24 and 36 volts
  • Fish finder connects wirelessly

REASONS TO AVOID

  • Electric-steer only
  • Few shaft choices
  • Noisy foot pedal

Although at #2 on our list, the Garmin Force is another great saltwater trolling motor. It has a futuristic design and is praised for its quick and accurate GPS anchor mode.

It uses a brushless motor, which helps it to reduce noise, including electromagnetic noise that can interfere with your fish finder readings.

“The speed, power and silence of the motor is crazy. When it’s on 50% or less, you will tend to look down every once in a while to see if the motor is running because it’s that quiet.”

[Texas Fishing Forum]

You can run the Force on either a two (24v) or a three-battery bank (36v) for more available thrust.

Although Garmin rates its trolling motor at 100 peak thrust, its thrust ratings are very conservative. In real life, the Force is just as powerful or even exceeds the performance of some of the models on this list.

The Garmin Force is designed for saltwater and freshwater use. The motor itself is made of stainless steel and aluminum.

The main downside: it is expensive.




Lowrance Ghost

BEST SALTWATER TROLLING MOTOR FOR ESTUARY USE

SPECIFICATIONS

Style: Bow Mount   Thrust: 97 lb (24v), 120 lb (36v)   Shaft length: 47″, 52″, 60″   Steering: Electric-steer   Wireless Remote: YES   Speeds: Variable   Use in: Saltwater (Estuary-only)

TODAY’S BEST DEALS

REASONS TO BUY

  • Brushless motor works on either 24V or 36V
  • Easy integration with Lowrance fish finders
  • High-quality transducers
  • Precise GPS anchoring

REASONS TO AVOID

  • Electric-steer only
  • The longest shaft available (60″) is not long enough for some boats

Lowrance is a U.S. manufacturer of GPS, sonars, and fishing electronics. Their first trolling motor was released in 2020, but it quickly became a hit.

The Ghost combines a powerful brushless motor with Lowrance high-quality sonars and reliable GPS anchoring.

Brushless motors are great for many reasons. They are more efficient, quieter, and cause less interference with your fish finder. Also, you don’t need to worry about replacing worn brushes in the future.

As everyone above has said, the Ghost is fantastic. The spot lock is killer, ours never hunts unless there is no breeze or current, once we did all the calibrations, its solid.

[BBC Boards]

The Ghost works with 24v and 36v battery banks for larger boats. Traditional lead-acid as well as lithium batteries can be used.

Originally the Ghost was released for use only in freshwater. Any type of saltwater would void your 3-year warranty. However, in 2020, Lowrance announced a prop shaft anode that allows use in brackish water without voiding the Ghost trolling motor warranty.

Brackish water, according to Lowrance, means “estuary use”. You still can’t fish in the ocean, it will void your warranty.

8 Things You Should Know Before Buying a Saltwater Trolling Motor

There are hundreds of different trolling motors models, and thousands if you count various thrust, shaft and feature configurations.

They can be quite expensive too, so before you buy one, make sure you educate yourself to avoid a potentially costly mistake.

Below, we’ll discuss the most important questions you should ask yourself and important things to know before deciding which motor to buy.

1. Saltwater Resistance

Most trolling motors are clear about whether you can use them in saltwater.

Saltwater is much more corrosive than fresh water and requires different materials.

For example, Minn Kota and Motorguide saltwater motors are built with premium-grade alloys, coated with zinc, and corrosion-resistant polyester paint. Each model comes with a sacrificial anode fixed to the prop. This will ensure your motor will last much longer.

If you use a freshwater trolling motor in saltwater, it will often void your warranty.

2. Mounting Location: Bow or Transom

You have three different locations and the corresponding trolling motor types:

  • Bow mount
  • Transom mount
  • Engine mount

Bow mount trolling motors are very popular because pulling rather than pushing makes the boats easier to maneuver. They often come with more advanced steering features, like GPS anchoring.

If you’re looking for a cheaper option or don’t want to put anything on your bow, transom mount trolling motors can be the right choice. Many anglers like them for simplicity, as they steer in a similar way to outboards.

Engine mount trolling motors are fixed to the cavitation plate of outboard motors. You don’t have to stow or deploy them. They are remotely controlled and steer together with the outboard.

3. What Size Saltwater Trolling Motor Do I Need?

Thrust is the force that moves the boat through the water. It is measured in pounds (lbs) and gives you a rough idea of the motor’s performance.

A generally agreed rule is that for every 100 lbs you will need at least 2 lbs of thrust. For example, if your boat weighs 4000 lbs, fully loaded, then you want 4000/100 * 2 lbs = 80 lbs of thrust for your trolling motor.

My advice is to get the most powerful motor you can. If you fish offshore on a large boat, you will be much better off with a 100+ lb trolling motor that runs at 36V.

You will also want more thrust if you fish in areas with fast currents and significant waves. The last thing you want is for your boat to be underpowered.

Learn more in our thrust guide.

4. Steering Options

Electric-steer trolling motors offer more control options, such as using wireless remote and GPS positioning that help you get where you want to be and focus on fishing.

Cable-steer motors have a multi-function foot pedal that is directly linked to the lower unit via a cable. It’s a less sophisticated system than the electric one but more responsive and very popular for bass fishing.

Hand-steer models use a tiller handle for direct control, very much like traditional outboards.

5. Batteries and Run Time

This is one of the most frequently asked questions and depends directly on two things: the capacity of your battery and the current draw of your trolling motor.

Battery capacity is measured in Ampere hours or Ah and current draw in amperes (amps). If your battery has 100Ah capacity and your motor draws 20 amps of current, then you can calculate its run time by dividing 100/20 = 5 hours.

However, this is only a theoretical number because depending on the type of battery you use, you will never want to deplete it to 0% of capacity. For example, if you have a standard lead-acid battery, you should really only use 50-70% of its Ah capacity if you want to keep it in good shape.

The current draw of your motor depends on the speed you set it to and how heavy your boat is. If you use your trolling motor at lower speeds, you will have a significantly lower current draw and much longer run time.

Weather and water conditions will also affect how long your motor will run. It is harder to push a boat against the current, choppy waters, or into the wind, which means higher current draw and shorter run time.

6. Calculating the Shaft Length

Selecting the right shaft of your trolling motor is vital. The shaft must be long enough for the propeller to stay submerged at least 16″ below the water line regardless of water and weather conditions.

You don’t want the propeller to get out of water in choppy waters or/and suck in air from above the waterline when it is not deep enough.

It will cause noise, and loss of power and can shorten the life of your motor.

7. Spot-Lock and GPS Navigation

GPS trolling motors, e.g. Minn Kota’s i-Pilot or Motorguide’s Pinpoint GPS, let you steer, control speed, lock onto fishing spots, and more just by pressing a button on the remote.

GPS anchoring is probably the most popular feature on premium trolling motors, and it’s fantastic in areas with substantial currents, waves, and winds.

It holds the boat at a set position by automatically thrusting whenever the boat starts to drift.

8. Fish Finder Compatibility

If you have a fish finder of a specific brand and you want it to be able to “talk to” your trolling motor, you will need to make sure they are both compatible.

For example, a Humminbird fish finder will work with Minn Kota’s models, whereas a Lowrance fishfinder works well with MotorGuide trolling motors.

Premium motors have built-in transducers that send images to your fish finder. They are fully integrated with the lower motor section, which means there are no additional cables or connectors involved.

If you want a built-in transducer, make sure it is of the type you want, for example, Universal Sonar or MEGA Down or Side Imaging.

Saltwater Trolling Motor FAQ

Can you use a regular trolling motor in saltwater?

Technically you can, but it’s not recommended for serious anglers. If you use a freshwater trolling motor in salt water it will corrode much faster, it will also usually void your warranty.

Is it OK to use a saltwater trolling motor in freshwater?

Absolutely. A saltwater trolling motor will be fine in freshwater.

How do I know if my trolling motor is saltwater-capable?

Each trolling motor description should state clearly whether it can be used in saltwater.

What materials are these motors built with?

For example, Minn Kota and Motorguide saltwater motors are built with premium-grade alloys, coated with zinc, and painted with corrosion-resistant polyester paint.

What is a sacrificial anode?

It’s a piece of metal fixed to the prop. The anode is made of a material that prevents your motor from rapid rusting.

Can you use an electric trolling motor in saltwater?

Yes, you can use electric trolling motors in saltwater. However, you need to be careful about which motor you choose and how you maintain it. Some motors are not designed for saltwater use and will corrode quickly. Others may require special maintenance to prevent corrosion. Be sure to read the manufacturer’s instructions carefully.

What happens to a freshwater trolling motor in saltwater?

If you don’t take proper care of a freshwater trolling motor, it will corrode and break down much faster than it would in freshwater. Saltwater is much more corrosive than freshwater, so it’s important to take extra steps to protect your trolling motor if you’re using it in saltwater.
