Mercruiser 8.1L Pitot code

I have a 2008 Epic 23v that since ive had the boat has always had a fault for the Pitot, so been told that my boat does not even use that sensor but theres no way to get rid of the code. Seems strange to me that there would be a code for something the boat doesnt even use/need. Really would love to get the code gone. Had a local shop hook scanner and he said he was not able to disable it or clear it

I found a plug off the engine for pitot back at my engine and its not plugged into anything. Kinda annoying to have the system fault always come up when i turn the boat on. was hoping theres some way to fix it
