Troubleshooting & FAQ

How do I know if this ignition switch fits my Honda motor?

This switch is for Honda BF115, BF135, BF150, BF200, and BF225 outboards. To confirm fitment, please verify that your original part number is 35100-ZV5-013 and that your switch uses a 6-wire connector. Checking these details against your current part is the best way to ensure compatibility.

What is the "push-to-choke" feature?

The push-to-choke function allows the operator to prime the engine with fuel for a cold start. When the key is in the 'Run' position, pushing it inward activates the choke system. This is a common feature on many outboard ignition systems.

What are common signs of a failing ignition switch?

Symptoms of a bad ignition switch include the engine failing to turn over, intermittent power to the console or gauges, the key feeling loose or difficult to turn, or the starter motor continuing to run after you release the key from the 'Start' position.

Is this a 3-position or 4-position switch?

This is a 3-position switch providing Off, Run, and Start functionality. It also includes the integrated push-to-choke capability.
