- Mercruisre MX 6.2 MPI with Bravo III (repowered from 7.4)
I have a new 6.2 with closed cooling in a 1999 Sea Ray 260 Sundancer and the engine has failed after only 36 hours on it. I have babied it since it was installed last September 2014 only going over 4,000 after 20 hours. I was running 22 pitch props but it would only rev to only did 4,200 RPM at WOT so I switched to Hill 4 blade Signature 18 pitch props. On the first test run, I got it got to 4,800 but then engine lost power. There were no alarms. When I put in neutral it died. When I got it restarted, it was missing terribly so cut it off and got tow to slip. I called Mercruiser and they said have local Mecruiser dealer ck it out. He quickly determined that there was no compression in two cylinders and low is the next one, all on the right side. The plug electrodes were gone in the cylinder with no compression. This seems un-real to me. Engine goes bad in first 36 hours! Anyone have similar issue with 6.2?
