To sum up, depends on your boat but my 2015 just needed an update/reflash of the ECU via a known PCM issue, fixed issue no more problems.

O2 sensor(s) need replaced

call PCM

And besides that..... why is your engine reading 194 with the engine running???

thid highest mine will ever read with the engine running is 175... If I shut it down quickly after a long run it may spike to 185 with the engine off.

when is the last time you changed your impeller?

Yes, I did not notice that the first time around....looks like you are running a higher temp so maybe something more/different than just a PCM reflash.

I noticed the temp as well. Must be the impeller.

Yep... Get your impeller changed immediately. I'd be willing to be the fins are chewed up some... When you do swap out take a pic for us.

if you were running 190s+, no wonder you were getting error messages. Replace the impeller before you do anything else... I bet the messages go away.

And that pic up there also underscores one of my recommendations for 2017 Nautiques and beyond:

300amp alternator.... Or perhaps dual 200 alternators.

the only time these boats read 14.2v+ at the dash is at 2000-3000rpms. Over or below that range you are in the 13s.

they should read 14.2 - 14.4v almost always.... Unless you are hammering the stereo, running all pumps etc.
