I have a 2022 Mercury EFI 20 hp outboard that went in the drink I pulled it out pickled it myself now have the engine light and buzzer on constantly after giving it some RPMs for a few seconds and dropping to an idol they go off and Buzz and blink a few times I have unplugged the buzzer it's annoying after a while I've gone through cleaned all the connections done everything I could possibly think anyone have any input for me it'd be greatly appreciated thank you for your time
 
I have the same motor and it also was submerged while running. I pickled it around 2hrs after recovery however the engine light stays on and the motor won't idle. i replaced the oil pressure sensor switch but it made no difference.

Update : I unplugged all the wiring connections, removed the ECM and put it in a zip lock bag with desiccant silica packets , tented the motor and ran a space heater and fan in the tent for 4 days. I reconnected everything and the motor runs normal and the engine light no longer stays on after it starts.
