Engine Compatibility

This ignition key is not engine-size specific. It is matched by ignition key code, not horsepower, engine model, or drive model. Mercury parts diagrams show 30431126 in ignition switch key chart references for electrical, remote control, steering, and accessory component groups using the 89491 and 30431 series ignition switch key system.

Serial Number Fitment Notice

Confirm the required key number before ordering. The correct match is the 126 key code, usually verified from the existing key, ignition switch key chart, or stamped key-code reference. Do not order by engine serial number alone, since ignition keys are matched to the switch/key code rather than the engine model.

When This Part Needs Replacement

Replace this key if the original is lost, bent, worn, cracked, difficult to turn, or no longer operates the ignition switch smoothly. A spare key is also useful to keep onboard or in a secure location for emergency access.

Installation Notes

No mechanical installation is required. Confirm the ignition switch uses key code 126, then test the key gently in the switch before regular use. Do not force the key if it does not turn smoothly, as the switch may use a different key code or the ignition cylinder may be worn.
