Looking for any feed back on similar experience, 2012 Etec 250 HO dropped the #3 & #4 cylinders (zero compression). Motor has 250hrs on it and was serviced at the dealer last fall. Was running down the lake and just lost power. No alerts or alarms and had good water pressure. Generally cylinder failure is from over heat or lack of lubrication - the crazy thing is that the other 4 cylinders are still at 120psi.
I really didn’t think my post was hard to read so I’ve tried to be more descriptive - sorry for any confusion.
