E Oxygen/O2 Sensor for Mercury Outboard 175–600HP (8M0142695)

The oxygen sensor is one of the most common failure points on Mercury Verado engines, and a faulty one can cause your engine to consume double the fuel it normally would — costing you serious money every time you leave the dock. If your engine has been running rich, throwing fault codes, or showing poor fuel economy, this sensor is often the culprit.

This is the OE (Original Equipment) replacement sensor, ensuring a direct fit and reliable performance. Compatible with Mercury Verado outboards from 175 to 600HP.

Also supersedes older part number: 8M0095468

Pro Tip: When replacing a failed O2 sensor, it's best practice to also replace your spark plugs — a rich-running condition can foul plugs and lead to misfires. Shop the matching NGK Spark Plug Kit here.
