Keep your Mercury or Mariner oil injection system operating properly with a genuine Mercury Quicksilver 12886A6 Oil Tank Sensor Switch. This OEM switch monitors the oil level in the engine-mounted oil reservoir on select Mercury and Mariner 2-stroke outboards.
A malfunctioning oil level sensor can cause incorrect oil warning indications even when the oil reservoir contains the proper amount of oil. Replacing a failed switch with the correct OEM component helps restore proper oil-level monitoring and warning-system operation.

What Does the 12886A6 Sensor Do?
The 12886A6 switch is part of the outboard's oil injection warning system. Installed in the engine-mounted oil tank, it detects oil level and works with the engine's warning system to alert the operator when a low-oil condition is detected.
If you are troubleshooting an oil warning alarm even though the engine-mounted reservoir is full, the oil level sensor and its associated wiring are components that should be inspected as part of the diagnostic process.
Genuine Mercury Quicksilver Replacement
Using the correct OEM oil sensor helps maintain the operation of the factory-designed oil injection warning system. The 12886A6 is manufactured for the Mercury and Mariner applications in which this switch was originally specified.

Important Fitment Information
Mercury used different oil injection components across engine families, production years and serial-number ranges. Horsepower alone should not be used to determine compatibility.
Before ordering, compare your existing part number or verify compatibility using your Mercury outboard's model and serial number.
