Problem #1: Motor Not Turning On

One of the primary concerns users may encounter with the Minn Kota Terrova 80 is when it fails to power on or respond to commands, rendering it unusable.


  • Faulty electrical connections: Loose or corroded electrical connections can prevent the motor from receiving power.
  • Dead battery or insufficient power supply: If the battery is dead or does not have sufficient charge, the motor will not turn on.
  • Defective control module: A malfunctioning control module can cause the motor to be unresponsive.


  • Ensure all electrical connections, such as battery terminals and wiring harnesses, are securely attached and free of corrosion. Clean and tighten any loose connections.
  • Check the battery voltage and charge level to ensure it meets the required specifications. If the battery is low, recharge or replace it.
  • Inspect the control module for any signs of damage or malfunction. If necessary, contact the manufacturer for a replacement.

Problem #2: Erratic Steering or Directional Control

Erratic steering or difficulty maintaining a consistent direction while using the Terrova 80 can significantly impact the boating experience.


  • Loose or damaged steering components: Loose cables, linkage, or damaged steering components can result in imprecise steering control.
  • Interference with the GPS signal: External factors like electronic devices or wiring can interfere with the GPS signal, affecting the motor’s directional control.
  • Water intrusion affecting internal components: If water enters the motor and affects the internal components, it can lead to steering problems.


  • Inspect the steering components, including cables and linkage, and tighten or replace any loose or damaged parts as necessary.
  • Identify and relocate any potential sources of interference, such as electronic devices or wiring, to minimize their impact on the GPS signal.
  • If water intrusion is suspected, remove the motor from the water and inspect it for signs of damage or corrosion. Properly seal any openings or replace damaged components.

Problem #3: Excessive Noise or Vibration

Excessive noise or vibrations emanating from the Minn Kota Terrova 80 can diminish the overall enjoyment of boating.


  • Misaligned propeller or motor shaft: Improper alignment of the propeller and motor shaft can result in excessive noise and vibrations.
  • Damaged or worn-out propeller: A damaged or worn-out propeller can cause imbalance and generate excessive noise and vibrations.
  • Loose or damaged mounting hardware: Loose bolts or damaged mounting hardware can contribute to noise and vibration issues.


  • Check the propeller and motor shaft alignment, ensuring they are correctly positioned and not rubbing against each other. Adjust the alignment if necessary.
  • Inspect the propeller for any signs of damage or wear. Replace the propeller if it is bent, cracked, or worn-out.
  • Tighten all mounting hardware, including bolts and screws, to eliminate any looseness or rattling.

Problem #4: AutoPilot Feature Not Functioning

The AutoPilot feature on the Minn Kota Terrova 80 provides convenient and hands-free navigation, but it may encounter problems at times, limiting its functionality.


  • GPS signal interference or weak satellite reception: Interference from structures or electronic devices can disrupt the GPS signal, affecting the AutoPilot feature.
  • Outdated software or firmware: Outdated software or firmware can cause compatibility issues and prevent the AutoPilot feature from working correctly.
  • Faulty AutoPilot control module: A malfunctioning control module can result in the AutoPilot feature failing to function properly.


  • Identify and minimize potential sources of interference that may disrupt the GPS signal. Move away from structures or electronic devices that may be causing interference, or recalibrate the AutoPilot feature in an open area.
  • Ensure the software and firmware of the Terrova 80 are up to date. Visit the manufacturer’s website to download and install any available updates.
  • If the issue persists, contact Minn Kota customer support for further assistance and troubleshooting guidance.

Problem #5: Propeller Stuck or Jammed

A stuck or jammed propeller can hinder the performance of the Terrova 80, impeding its ability to operate smoothly.


  • Debris, weeds, or fishing line entangled in the propeller: Accumulated debris, weeds, or fishing line can become entangled in the propeller, causing it to jam.
  • Bent or damaged propeller shaft: A bent or damaged propeller shaft can impede the rotation of the propeller, leading to a stuck or jammed situation.
  • Insufficient lubrication: Inadequate lubrication of the propeller shaft can result in friction and cause the propeller to become stuck.


  • Carefully inspect the propeller for any debris, weeds, or fishing line entanglements. Remove any obstructions, ensuring the propeller spins freely.
  • Examine the propeller shaft for signs of bending or damage. If the shaft is bent, replace it to restore proper functionality.
  • Apply a suitable lubricant to the propeller shaft as recommended in the Terrova 80’s user manual to ensure smooth operation.

Problem #6: Remote Control Malfunction

A malfunctioning or unresponsive remote control can diminish the convenience and functionality of the Terrova 80, requiring immediate attention.


  • Low battery level in the remote control: A low battery level can cause the remote control to become unresponsive or function intermittently.
  • Interference with the remote control signal: Interference from other electronic devices or metallic structures can disrupt the signal between the remote control and the Terrova 80.
  • Defective remote control unit: A defective remote control unit may exhibit erratic behavior or fail to function altogether.


  • Replace the batteries in the remote control with fresh ones to ensure optimal performance. Check the manufacturer’s guidelines for the appropriate battery type and installation.
  • Avoid operating the remote control near potential sources of interference, such as other electronic devices or metallic structures, to maintain a clear signal.
  • If the remote control remains unresponsive or exhibits persistent issues, contact Minn Kota customer support for further troubleshooting or a possible replacement.

Problem #7: Overheating Motor

Overheating of the Terrova 80’s motor can occur under heavy usage or in hot weather conditions, potentially causing performance issues and requiring attention.


  • Insufficient cooling due to debris or weeds blocking the cooling system: Accumulated debris or weeds in the cooling system can obstruct airflow, leading to motor overheating.
  • Continuous high-speed operation for an extended period: Prolonged operation at high speeds without intermittent cooling can cause the motor to overheat.
  • Faulty or damaged cooling components: Malfunctioning or damaged cooling components, such as the water pump or thermostat, can contribute to motor overheating.


  • Regularly inspect and clean the cooling system of the Terrova 80, ensuring there are no obstructions that hinder the motor’s heat dissipation. Remove any debris or weeds that may have accumulated.
  • Avoid operating the motor at maximum speed for prolonged periods. Allow the motor to cool down intermittently during extended use to prevent overheating.
  • If the overheating issue persists despite these measures, consult a professional technician or contact Minn Kota customer support for further assistance.
