  4. Remove any mounting nuts or clips and take out the old switch.
  5. Insert the new ignition switch into the mounting hole and secure it.
  6. Firmly connect the wire harness to the terminals on the new switch.
  7. Reconnect the battery, attach the safety lanyard, and test the Off, Run, Start, and choke functions.

Troubleshooting & FAQ

How does the push-to-choke feature work?

When the key is in the "Run" position, pressing the key inwards activates the engine's choke circuit, which enriches the fuel mixture for easier cold starts. Release the key once the engine is running smoothly.

Will this fit my specific Suzuki remote control console?

This switch is designed for compatibility with the OEM remote control boxes used for the listed Suzuki engine models. Always compare the wiring connector and physical dimensions of your old switch to our product images to ensure a perfect match.

What are common signs that my ignition switch is failing?

Symptoms of a faulty switch include the engine not cranking, intermittent power loss to gauges, the key feeling loose or failing to turn properly, or the starter continuing to run after the key is released from the "Start" position.

What is the difference between OEM and aftermarket parts?

This listing is for a high-quality aftermarket replacement part, not an original equipment manufacturer (OEM) component.

How fast is shipping and what does it cost?

We ship worldwide quickly, with typical transit times of 5–15 days for most regions. Standard shipping is free on all orders. Expedited shipping options and their costs will be displayed at checkout if available for your location.

This product is covered by a 1-year warranty against manufacturing defects under normal marine use. If you encounter any issues, please contact our support team with your order details. Returns are accepted within our standard window for unused items in their original condition. See our full policy page or reach out for instructions.
