Good To Know
Q: Will this switch work on a standard Mercury 9.9 tiller model? A: Yes, it fits Mercury 9.9 2-cylinder outboards, including tiller and remote steer versions. Verify your serial number to confirm compatibility.
Q: Does this include the key? A: The listing covers the ignition switch only; keys are typically sold separately. Reuse your existing key if it matches the switch keyway.
