More about this item

Mercury Marine 893353A02 Ignition Switches

The key switch assembly is the starting point for every trip on the water, and when it stops working reliably, everything else comes to a halt with it. The Mercury Marine 893353A02 Key Switch Assembly is a genuine OEM replacement for compatible Mercury applications, restoring clean, dependable ignition switching to the helm without the guesswork of an aftermarket substitute.

Key switch assemblies on Mercury outboards and sterndrives handle more than just starting the engine. Depending on the application, the switch also manages choke functions, accessory circuits, and in some configurations, engine kill functions tied to the key position. When the switch begins to fail, the symptoms can range from intermittent starting issues and accessories that stop responding to a key that turns without engaging the starter at all. Corrosion inside the switch cylinder, worn contacts, and damaged wiring connections at the switch terminals are the most common culprits after years of marine service.

As a genuine Mercury Marine OEM assembly, the 893353A02 is built to the correct electrical specifications for compatible Mercury ignition systems. The switch contacts, terminal configuration, and key cylinder are all matched to Mercury's original design, ensuring the assembly integrates correctly with the engine's starting circuit and any accessory functions tied to the switch. It installs in place of the original and is compatible with Mercury keys in the appropriate key series for this switch.

Key Features:

  • Genuine Mercury Marine OEM key switch assembly
  • Part Number: 893353A02
  • Compatible with Mercury outboard and sterndrive ignition systems
  • OEM switch contacts, terminal configuration, and key cylinder
  • Manages starting, accessory, and choke functions as applicable

Confirm your engine model and serial number before ordering. Mercury key switch assemblies vary by application, control panel configuration, and production year. Verifying the correct assembly for your helm setup ensures proper fit, correct terminal wiring, and full switch function from the first turn of the key.
