how to install electric start on snowmobile

Adding an electric start to a snowmobile can be a convenient upgrade, especially in cold weather. However, it’s important to note that the complexity of this installation may vary depending on the make and model of your snowmobile. Here is a general guide on how to install an electric start on a snowmobile:

Materials You’ll Need:

  • Electric start kit (compatible with your snowmobile)
  • Basic hand tools (socket set, wrenches, pliers, screwdrivers)
  • Safety goggles and gloves
  • Service manual for your snowmobile (for specific instructions)

Important Considerations:

  • Ensure that the electric start kit you purchase is designed for your specific snowmobile make and model.
  • Disconnect the snowmobile’s battery before starting any work.
  • Consult your snowmobile’s service manual for specific instructions and torque specifications.


  1. Safety Precautions:
    • Put on safety goggles and gloves. Ensure the snowmobile is on a stable surface, and disconnect the battery to prevent electrical accidents.
  2. Gather Information:
    • Consult your snowmobile’s service manual to understand the specific requirements and instructions for installing an electric start on your particular model.
  3. Locate a Suitable Location:
    • Determine where you want to install the electric starter motor and the associated components. This location should allow proper alignment with the snowmobile’s existing drive system.
  4. Mount the Starter Motor:
    • Install the starter motor in the chosen location using the mounting brackets and hardware included in the kit. Ensure that it is securely fastened.
  5. Install the Starter Bendix or Gear:
    • The starter bendix (or starter gear) is the component that engages with the snowmobile’s primary clutch to turn the engine over. Follow the kit’s instructions to install this component, ensuring proper alignment with the clutch.
  6. Wiring Installation:
    • Connect the electrical wires and cables as specified in the kit’s instructions. This typically includes connecting the starter motor to the starter relay and the relay to the battery. Ensure all connections are secure.
  7. Install the Starter Button or Key Switch:
    • Mount the starter button or key switch in a convenient location on the snowmobile’s handlebars or dashboard. This is the control mechanism for activating the electric start system.
  8. Battery Connection:
    • Reconnect the snowmobile’s battery.
  9. Test the Electric Start System:
    • Turn the key or press the starter button to engage the electric start system. The starter motor should turn over the engine smoothly. If it does not, double-check all connections and wiring.
  10. Reassemble and Secure Components:
    • Reassemble any snowmobile components that were removed during the installation process, such as the snowmobile’s body panels.
  11. Final Checks:
    • Before using the electric start system regularly, test it multiple times to ensure its reliability. Check for any unusual noises or issues.
  12. Test Ride:
    • Take the snowmobile for a test ride to verify that the electric start system works as expected. Monitor the engine’s performance during the ride.
  13. Maintenance:
    • Regularly inspect the electric start system for signs of wear or damage. Keep all connections clean and secure.

Please note that this is a general guide, and the installation process may vary based on your snowmobile’s make and model and the specific electric start kit you have. Always consult the manufacturer’s instructions included with the kit and refer to your snowmobile’s service manual for any model-specific details. If you’re not comfortable with the installation process, consider seeking assistance from a qualified mechanic or technician.
