Why Is My Trolling Motor Running Slow? 7 Top Reasons Behind

A trolling motor incorporates an electric motor that remains affixed to either the stern or bow of the boat. It leads a boat to be in the right spot and lets it fight against wind or current.

But, it can run slower than it should be which takes the entire boating process down. So, you’ve to figure out the actual reasons before you go for the solutions. And, here’re 7 top possible reasons for your trolling motor to be slower. Figure out which one is yours-

Reason-1: Poor Maintenance

Trolling motor requires regular maintenance to provide top performance. If you fail to do its accurate maintenance on a regular basis, it will become slower.

Reason-2: Old Batteries

It’s a very common reason for trolling motors to be running slower if the battery gets older. The older battery is often unable to offer high speed for trolling motors.

Reason-3: Turbulent Water Condition

While the water body is with lots of waves, the trolling motor starts running slower. Vice versa! It is because of the strong wave effects on the battery performance.

For instance, if you need 20 AMP to run in the calm water body to maintain a standard speed, the AMP will be required at 30 in the case of turbulent water conditions.

Reasons-4: Debris Condition

If the trolling motor gets debris in it, or in the fishing lines, it will tangle up in the propeller. And, this dusty condition is another significant reason to make your trolling motor run slower.

Reason-5: Wrong Connection or Wrong-Sized Wiring

If the connection doesn’t go through the right track, the trolling motor will slow down. Again, if you use any broken or wrong-sized wire, the trolling motor will also run slower.

Reason-6: Poor Prop Condition

It happens with people when they hit the stump because hitting the stump can cause the prop to become bending. 

And, if the prop gets bent, the trolling motor will become slower. Again, if the prop won’t spin accurately, it will cause the trolling motor to run slower.

Reason-7: Low Battery Charge

Battery charge is another major issue for the performance of trolling motors. The battery with a low charge will make the trolling motor perform slower.

How Can I Make My Trolling Motor Runs Faster? Key Solutions

The 7 reasons that we have discussed above are the highly recognized reasons for trolling motors to run slower. Once you can make out the exact reason among these 7, you’ll be able to solve your problem in a while. So, let us help you identify what to do if you’re having any one of those 7 reasons-

Will a 3 Blade Prop Make My Trolling Motor Faster?

The 4-blade prop offers all the improved characteristics to ensure your boat’s performance.
