Engine serial number is 1A652875. The boat was bought used from a guy (he was the original owner), not used from a dealership, and always used in fresh water. Im going to try to get to the boat today to check the operating temps however, I do check the temps all the time and they are never what I would consider off. Thanks again for your help.

just to let you know the engine was changed out under full warranty with very little engine hours and has a different engine serial number than original engine. I do know the current engine serial number thou.
Anyways so what temps is the engine running at since you mention normal ? different engines have different normal running temps.
IMO your O 2 sensor (s) possible are getting contaminated by something going thru the exhaust and or possible by water and or condensation.

^^^^^^^^^^^ In this thread I Posted alot info here to help out catalyst engine boat owners. My experience one I am trained indepth on Marine catalyst systems, 2 is Cat engines are not for everyone to work on especially with no experience. I see more boat owners and incompetent service shops cause more harm than good and in return really causes huge expense to get systems fixed correctly after the fact.
Two - I hate when I spend my time to offer very solid indepth FREE info that I had to pay for to gain and that person never comes back up to say it fixed it or not. They disappear once they get what they want for info like the poster above. The dude made 5 total posts here on OSO but failed to comeback up for the 6 post to give updates. Anyways --- you need to post your engine serial number - hours on the engines and was the shop that work on your app competent ? Also is your app totally stock ? and is your exhaust totally stock ? do you have captain call exhaust ? meaning switchable exhaust -

I installed the Vesselview Mobile device on my 2003 Sea Ray 280 Sundancer which has a single 496MAG S/N 0M376155. After the install and starting the boat I immediately have 5 fault codes. How do I determine if they are an issue and even applicable to my engine? Engine idles around 670-700RPM (is that normal, or low?).
-Code 451-25 Pilot Pressure (The input circuit for the sensor is below the valid limit)
-Code 701-24 Level sensor tank A (The input circuit for the sensor is below the valid limit)
-Code 1031-24 Steering Position (The input circuit for the sensor is below the valid limit)
-Code 1012-25 Engine or drive trim position (The input circuit for the sensor is below the valid limit)
-Code 702-24 Level sensor tank B (The input circuit for the sensor is below the valid limit)
Thanks in advance! For all I know, these codes aren't applicable to my engine or don't mean anything...

OK, according to Mercruiser:
"All the faults you mention below are for optional sensors, some are not installed on most boats. Basically the engine is looking for sensors that are not installed and don't need to be there. You can ignore or silence these faults within the vesselview mobile app. Dealers have service manuals and software that lists faults for the engine. The idle RPM for your engine seems normal. If you have some of these sensors installed, for example a smartcraft style fuel tank sender, have a dealer diagnose the sender and circuit for problems.
Thanks,

We bought a 2012 Sea Ray Sundeck 240 with a Mercruiser 5.7 Bravo. Since we bought it we are getting a code 48 stbd exhaust oxygen sensor not working properly. We had our mechanic replace the precat sensor and reset the code. 2 hours later we got the same code so he replaced the post cat sensor. Not even an hour into that we got another code 48 and now are getting a code 50 as well. Any thoughts? We are extremely frustrated. Thank you.
