Exhaust manifold overheating - Factory defect?

[Crjcarr]

I took my 2012 210 SANTE out on the delta yesterday for the first time, and experienced a cryptic error code (see photo). "DTC 1415: EMWT1 higher than expected stage 1". I immediately called the dealership (Buxton Marine, TX) and they told me that this was 'known issue' and they've already seen a handful of cases from the 2012s. Anyone had an issue with this? The service tech at Buxton told me this is a problem with the impeller that cools the exhaust manifolds, which results in External Manifold Water Temp (EMWT) getting too hot.

On a side note: thanks to Buxton for helping me out, and it's just sad that I have to call TX because my local Nautique dealer (Central Valley Marine, Campbell, CA) doesn't have anyone on hand that can help at noon on a saturday.

Update: I had the boat repaired under warranty. It turns out this was a factory defect with the 2012 PCM343's and Nautique/PCM are both aware of it (from what I was told) Superior Boat in Sacramento and Buxton Marine in Coppell, TX have both seen a handful of these exact cases already this year on the 2012s. Just thought I'd update this in case anyone else sees the same error code.

What exactly did they do to repair it?
