How to Match This Part
This aftermarket oxygen sensor replaces Yamaha 65L-8592A-01 (catalog form 65L-8592A-01-00). It threads into the exhaust on selected Yamaha V6 two-stroke HPDI and EFI outboards from 150 to 250 HP and reports exhaust oxygen so the ECU can trim fuel. This unit is new production, not a remanufactured core.
Match this part in this order:
1. OEM number on the removed sensor or in your parts catalog (65L-8592A-01 / 65L-8592A-01-00, 65L-8592A-00 / 65L-8592A-00-00, or 68F-8592A-00 / 68F-8592A-00-00)
2. Model code and year in the table below
3. Physical form — hex body, slotted tip, integral lead with an inline cylindrical module, and a two-piece plug
This is not Yamaha 67H-8592A (the two 2-pin-connector sensor used on DX/LX/SX/VX 150–200). If your original uses two small 2-pin plugs and no inline module, order the 67H listing instead.

Installation Guide
1
Allow the engine and exhaust housing to cool fully. Disconnect the battery negative cable before unplugging the sensor lead.
2
Note the routing of the two-piece plug and inline module, then unplug the connector. Unscrew the old sensor from the exhaust housing with an oxygen-sensor socket on the hex — do not pull on the lead or crush the inline module.
3
Confirm the OEM number and the inline-module / two-piece-plug layout match this 65L-8592A-01 assembly. Thread the new sensor in by hand, then tighten snugly on the hex. Follow the Yamaha service manual for your model for tightening and thread treatment.
4
Reconnect the two-piece plug until it locks, restore the battery, start the engine, and confirm there is no exhaust leak at the bung and that the EFI/HPDI system runs without an oxygen-sensor fault.
Note: Professional installation is recommended to ensure safety and optimal performance.
