Do Trolling Motors Wear Out?

As with other motors, like the one on your car, trolling motors will wear out over time. Parts like bushings, brushes, and other internal components will experience wear and tear. As they do, they will begin to drag on your motor.

Over time, this means that the motor has to work harder than it once did to achieve the same speeds for your boat. Eventually, it will stop working entirely.

The exact lifespan of your particular trolling motor depends on the make and model of the individual unit.

You can search for the lifespan of your trolling motor online by googling the name of the trolling motor along with the word “lifespan”. This should give you at least an estimation of how long your trolling motor should last.

When you buy a trolling motor, take note of any warranty that comes along with it. This should be an indication of the minimum amount of time that the motor should last. If it doesn’t last that long, contact the manufacturer ASAP.

There are different kinds of car batteries available, which makes this a complex question. In general, though, a car battery should power your trolling motor at low speeds for about 10 hours before it is fully discharged.

However, using your car battery on a trolling motor takes its toll on your battery. Batteries designed for trolling motors are “deep cell” batteries.

These batteries are designed to discharge small amounts of energy over long periods and are easier to recharge when their power drops below 50%.

Most car batteries, on the other hand, are designed to discharge a lot of energy all at once. They are also not designed to have their power regularly drop below 50% or to recharge well from low power.

Thus, you can use a car battery on your trolling motor, but it damages the battery and, sometimes, the motor. The amount of damage depends on how far you go, how long you use the car battery, how powerful your motor is, and other factors.

Thus, it’s impossible to say how long a car battery could run your trolling motor before the battery dies completely.

  • How often your motor is on
  • How large your boat is
