I think you have two different issues. 1.) The pitot is usually a water pick up tube that feeds a sensor for speed info. to speedometer on outdrive boats. I think you can turn that off in vessel view somewhere. 2.) The low press. readings refer to the pressure the engine water pumps are creating and it looks like your port is low. I'm sure others will chime in to confirm or correct me.

 

Thanks. From what I can find so far, it looks like the port side water pressure is normal. The starboard side is off. Even with the motors off the right side read 35. The port was at 0.
