New 2015 230 throwing Exhaust Temp Warning

[Guntersville230]

Just got a new 2015 230 with the 343 and it keeps throwing warning code "DTC1415: EMWT1 higher than expected stage 1" warnings. I read in previous post that this was a known issue back in 2012-13 but I was uncertain if anyone had a similar issue in a 2015? My engine temps were all ok, water intake/outlets/filter are not clogged, so i'm at a loss, other than a defective sensor? Any one else had this experience?

This happened with my '12 210 TE with the 343. It was a factory defect that PCM corrected by installing new manifold cooling. Same error code, though. The EMWT01 is 'exhaust manifold water temp' which means either the water in your manifold is too hot ( not cooling enough to, manifold is overheating) or the sensors *think* the manifold water temp is too hot... Either way, probably a PCM issue that your local dealer can look into under warranty.

Thanks! Just a bummer its a brand new boat and already having issues....had a 98 Air from new until I traded on this boat (17yrs!!!) and never had a problem...had this boat a month and issues start.....sucks!

I had the same thing. I believe it was just a software update the dealership did to the link system when I had my first service.

[Guntersville230]

Was it a software update that fixed it OR a software update that caused it?

[seveet]

Fixed it.😀

Thanks! My dealership just called me back and said the same thing. Appreciate you taking the time to help me out!

Other 230 question, are you running the stock prop or change to the 1235?

I have had this same issue all summer. I too had the software updated by the dealer. The warning continued to appear consistently when the water temps were in the mid to upper 70's and the boat was being operated at a slow speed (7mph or less). When the warning came on, we would increase boat speed to improve cooling and then clear the warning. Now that the water temps are in the mid to low 60's, I have yet to see the warning.

Once I'm able to make it down to the dealer to get it flashed I'll follow up with if it fixed the issue

It will fix it. My 2015 210 did the same thing. Dealer ship "reflashed" took 15 mins and hasn't done it again.

I thought the 1235 was stock on 2015 230? From what I understand if you are surfing/wakeboarding that's the prop you need for that boat.

Honestly, I haven't checked the # on the prop yet. Its in dry storage now so I was going to check it the next time we go out and see what I have before I make any purchasing decisions.

Old thread, but I received this letter in the mail.

I got the same one last week.

I got the same one last week.

Have you already gotten the problem fixed or do you still have to take it in?
