Looking back at this, I'm confused. Ed h posted a copy of the notice on 8/19/14, but looking up the engines, the RS-3s named were cataloged in 2016. (?)
I have two of these engines, and don't recall getting any notice, but it appears the dealers passed the info on to their buyers. I bought mine from an on-line dealer. Never heard anything. I suspect most owners never heard anything about this.
