Good used OEM Mercury 200hp EFI ECU ECM Computer 14632A17 Freshwater. 1 of the wires has had a new end put on it, and another needs a new wire (as pictured) but the main harness is in good condition and undamaged. This part has a 30 day return and refund policy if it doesn't work. The engine this part came from was run in freshwater only. Feel free to message me if you have any questions!
