Critical Alarm Question?

[RonH54]

Got a weird question. I keep my boat on a lift at a Marina. When I first put it on the lift it like at a 45 degree angle with Bow up and Stern low with water coming over transom some before I get out to lift boat up so my "Pee" hole is under water until I get boat up. Once every down and then I have the Critical Alarm beep go off on my Merc 225 efi while the boat is on my lift in this position. Never have any other type of alarm ever go off with this motor. My question, could the water being that high up on my motor and transom area cause this alarm? Or is it something I better go get the motor on a Computer?

Either way you'll need to get the Freeze Frame (Fault) History read. May be related, but either way it's something that needs to be corrected before running it again.

Please be sure to provide your engine's Serial Number (as that will help to determine which forum your engine belongs in). Moving to the 3L forum for now.
