2017 G21 Error Message - What Does This Mean??

[44BLUES]

I received the following error/warning message on my 2017 G21 and I can't find anything in the manual that describes what it means........has anyone ever seen this message and/or know what it means? All of my critical engine readings (engine temperature, oil pressure, etc) were within normal operating ranges and the boat ran fine but just want to make sure it's nothing major!?

Should I have this issue checked out by my dealer before the 'initial service' is done at 25 hours (boat currently has 10 hours)? Any advice would be appreciated

Send this picture to your dealer and they should be able to tell you what to do.

You can also search the internet for these codes and get some feedback. Bottom line the dealer is going to have to check it out. May or may not be a big deal but check it out with the dealer to CYA. Just had my 2016 G23 throw some codes this past weekend, likely something around a bad O2 sensor based on the codes I found on the internet.

Could be a blocked thermostat housing going to your exhaust risers. Should be somewhere near where the feed line tees to each one. I would run the boat like that because you could be over heating your exhaust risers and not notice a change in engine water temperature. I smoked a set of risers in a similar way.

Thanks for the advice! I had already contacted my dealer about it but I am still waiting on their response/recommendation.......just wanted to reach out to others for advice. Thanks again

Had a similar if not same error and everything seems fine. I'll ask my dealer as well.

Let us know what yours says.

I think it means you have to give me your boat... ;-) With a brand new boat, your dealer should be helping you out real fast.

Did you ever resolve this and find out what it was?

Just a follow up to my previous post but my issue was a shredded impeller that was causing codes. It never did look like the temp was getting to high and the codes it was throwing was pretty random stuff not "clear" like OVERHEATING,
