How to Use a Trolling Motor

How to use a trolling motor comes down to a short routine: mount it and set the depth so the propeller stays underwater, connect power with the controls off, lower the motor into the water, pick a low speed, and steer. At the end of the day you reverse the steps, raise the motor, disconnect the battery, and rinse and check it before the next trip. A trolling motor is the quiet, battery-powered motor anglers use for slow boat control; if you are still deciding what a trolling motor does and which mount style you have, start there.

This guide is general product information, not repair or electrical safety advice. Follow the installation, wiring, and charging instructions in your product’s manual, stop using any battery, charger, or electronics that overheat, swell, or smell of burning, and contact the manufacturer.

How do you use a trolling motor from launch to trailer? The steps below follow two owner’s manuals: Newport’s Kayak Series owner’s manual for a hand-steered transom motor, and Garmin’s Force trolling motor owner’s manual for a bow mount with a foot pedal, remote, and GPS features. Your motor may differ in the details, so keep its own manual within reach.

Before You Launch: A Two-Minute Check

• Battery charged. Newport’s manual says to recharge batteries after each use and to follow the battery maker’s recommendations, so the check really starts the night before.
• Propeller and wiring. The same manual’s daily maintenance list starts with checking behind the propeller for weeds, fishing line, or other debris, and includes checking for loose or corroded wiring connections.
• Controls in hand. On a remote-controlled motor, Garmin says to keep the remote on your person whenever the motor is in use, so you can stop the propeller from wherever you stand.
• Life jackets on. Newport’s safety section says users should always wear approved life jackets and should not let children operate the motor.

How to Use a Trolling Motor on a Transom Mount

A transom motor clamps to the back of a jon boat, canoe, or kayak mount. Newport’s first-time running steps go in this order:

1. Set the motor on the back of the boat in the stowed, tilted-up position.
2. Snug the transom mounting screws loosely, just until they grip.
3. Press the tilt lever and let the motor down into the water slowly.
4. Use the depth collar to set the height. Newport recommends a running depth of 6 to 12 in below the waterline.
5. Once the motor sits at a safe depth and clear of the bottom, tighten the mounting screws. The manual also warns against overtightening the bracket, to protect the fiberglass shaft.
6. Put the twist grip in neutral, then connect the battery with the terminal nuts tight.
7. Choose speed and direction with the twist grip.

To raise or lower the motor, Newport recommends disconnecting the battery first so it cannot start by accident, then holding the tilt lever while you move the motor by the handle and releasing the lever to lock it. The manual also says to disconnect the battery once the motor leaves the water, because a rotating propeller can cause injury.

Deploying and Stowing a Bow-Mount Motor

A bow mount folds onto the front deck for the run and swings down into the water to fish. Garmin’s Force manual walks through deploying it: unfasten the safety strap, pull the pull-cable back to release the latch, lift the motor up and forward, then lower it slowly into the deployed position. Stand on stable footing for this, since the manual warns about slick surfaces and pinch points in the moving parts. On a wet bass boat deck at dawn, that warning is practical, not theoretical.

Stowing has two details owners tend to skip. Garmin says to let the motor finish rotating to one side before lifting it onto the mount, or the steering system can be damaged, and to always fasten the safety strap afterward so the motor cannot deploy on its own while you run across the lake.

Depth on a bow mount is set at a collar too: Garmin has you hold the motor halfway between stowed and deployed, loosen the collar (expect the motor to slide), set the depth, and retighten, without going so low that the coiled cable gets compressed. Its current-draw tables assume the motor sits deep enough not to ventilate, which is a good rule of thumb in chop.

Choosing a Speed

On a tiller motor, speed lives in the twist grip. Newport’s Kayak Series has five forward and three reverse speeds: rotate the handle clockwise for forward, counterclockwise for reverse, and line the arrow up with 0 to stop. The manual warns not to go from full forward straight to full reverse without letting the propeller stop first, or the motor can be damaged.

On the Force, you raise and lower speed with buttons on the remote or a speed wheel on the foot pedal, and the bars on the mount’s display panel show the setting. Garmin’s specification tables show why lower settings matter. On a 24-volt supply, the manual lists about 14 A at 50% throttle against 57 A at 100%, so half throttle draws roughly a quarter of the current. In practice, fish most of the day in the low settings and save the top speed for crossing a cove or fighting wind. How long a single battery lasts at each setting is a separate calculation covered in the 12-volt run time guide.

Steering: Tiller, Foot Pedal, or Remote

• Tiller. On a transom motor, swing the handle the opposite way you want the bow to go, as with any tiller. Newport’s mount has a steering tension knob: loosen it for easy steering, or tighten it firmly to lock the motor’s direction while you fish a straight bank.
• Foot pedal. Garmin says to push the pedal with your toes and heel to steer, which keeps both hands free for casting.
• Remote. The Force remote steers with buttons, or with gesture controls once its compass is calibrated: hold a button and point the remote left or right. Garmin also asks for caution near trees, shallow rocks, docks, pilings, and other boats.

Using GPS Anchor and Heading Hold

GPS-equipped bow mounts can hold a spot or a heading for you. In Garmin’s terms, the anchor lock feature is an autopilot function that uses GPS to set and maintain your position using the trolling motor, acting as if you had dropped a physical anchor. Heading hold keeps the boat moving in the same compass direction.

At the concept level, using them looks like this on the Force:

1. Calibrate the motor’s compass first. Garmin requires this before any autopilot feature works and suggests doing it on calm water with little or no wind.
2. Drive to the spot you want to hold, such as the edge of a brush pile, and press the anchor lock button on the remote or pedal.
3. Nudge the held position if needed. Each press of an arrow key on the remote moves it 5 ft, per the manual.
4. Press anchor lock again, or steer with the pedal, to return to manual control.

These features assist you; they do not run the boat. Garmin says the operator stays responsible for safe operation, the controls should never be left unattended, and the autopilot features should be learned on calm, hazard-free open water, with the operator ready for sudden stops, acceleration, and turns. It also says to keep large metal objects such as a tool box away from the mount’s display panel, since they can interfere with the compass. Buttons and menus vary by model, so set up from your own manual.

When the Propeller Fouls or the Breaker Trips

Weeds, fishing line, nets, and silt are the usual trouble. Newport’s manual explains that a stalled electric motor keeps drawing very large current and builds heat that can damage the switch and other parts, which is why it strongly recommends a circuit breaker in the motor leads. Its instructions for a fouled prop are to disconnect the battery and clean the propeller, and not to increase thrust to push through it. If the breaker cuts power, disconnect the battery, clear the obstacle, press the reset button on the breaker, and reconnect.

On thick weed flats, the Force manual describes running with the motor only partially deployed to pass over weeds or submerged obstacles; past the halfway point, the propeller stops on its own as a safety measure. Before you reach for the propeller on any motor, Garmin’s warning applies: always disconnect the motor from the battery first.

Salt Water and Fresh Water

Check your maker’s rating before a saltwater trip. Newport’s trolling motor FAQ says its stainless steel and zinc hardware allow all Newport motors to be used in salt water, and its NV Series page describes that line as built for both salt and fresh water while adding that the motors are not corrosion-proof. The same page says storing the motor in fresh or salt water could void the two-year limited warranty, so take it off the water at the end of the day.

Rinsing is the habit that matters. After salt or brackish water, Garmin says to rinse the entire Force with fresh water, wipe on a water-based silicone spray with a soft cloth, and avoid spraying jets of water at the shaft cap. Newport’s manual says to rinse the parts that touched salt water and keep the top cover dry to protect the circuitry inside. Use your own motor’s version of this step.

After the Trip: Shut Down and Basic Care

1. Stow and disconnect. Turn the propeller off, raise or stow the motor (fasten the safety strap on a bow mount), and disconnect power. Newport says to do that when charging batteries, transporting the boat, or when the motor is not in use, which also keeps it from starting by accident on the trailer.
2. Look it over. Newport’s daily list includes clearing debris behind the prop, lubricating pivot points with a non-aerosol lubricant (it warns that aerosol propellants can damage parts), and checking nuts, bolts, and screws.
3. Recharge and store. Recharge the battery as its maker directs, and in freezing weather store the motor where it will not freeze, per Newport.

Bow mounts have a longer seasonal list. Garmin ties routine maintenance to the warranty and covers terminals, hinges, the latch, mount rails, and the sacrificial anodes, which it says must be examined each season. Follow that manual, or a qualified marine technician, for anything involving the wiring.

This guide isn’t for a first-time installation or rewiring. Bow-mount installs involve drilling the deck, routing heavy cable, and fitting a breaker, and Garmin’s Force installation instructions recommend a qualified marine installer for that job. If you are still choosing a motor, start with sizing instead: thrust and shaft length decide whether a motor suits your boat.

Frequently Asked Questions

How do I use a trolling motor as an anchor?

You need a motor with a GPS position-hold feature, such as Garmin’s anchor lock. Calibrate the compass on calm water, drive to the spot, and press the anchor lock button; the motor then works to keep the boat in place. A motor without GPS cannot do this on its own, so you hold position by steering and adjusting speed by hand, or use a physical anchor.

Can you use a saltwater trolling motor in freshwater?

Yes, where the maker says so. Newport describes its NV Series as built for both salt and fresh water. Check your own motor’s manual or product page for its rating, and keep up the freshwater rinse after any saltwater trip.

Can I run a trolling motor out of the water?

No. Garmin’s manual says not to run the motor with the propeller out of the water, because contact with the rotating propeller can cause severe injury, and Newport’s manual says to disconnect the battery once the motor leaves the water.

Why did my trolling motor slow down or stop?

Newport’s troubleshooting list for loss of power includes a damaged propeller, corroded battery connections, low battery voltage, and undersized wiring between the battery and the motor. A tripped circuit breaker or a prop wrapped in weeds can also stop it. Recharge the battery, clear the prop with the battery disconnected, and leave wiring faults to the manual’s instructions or a qualified marine technician.
