Yes,with old electronics
The first meltdown was due to old gas,and this time was due to piston failure(locating pin come loose)

double check your electronics....I just rebuilt mine and in 10 minutes of run time burned dwon the same two cylinders again. I thought the first blow up was due to bad gas, now I am thinking it was a fuel deliver problem....
Pretty sure I won't be getting any warranty out of my 7 year old motor.

I've been dyin' to ask this, but figured somebody else would beat me to it. If I understand all this right, here's what I can't figure out: You said the powerhead first blew from bad gas, and also someone rebuilt it as a home job. So how did you get Merc to warranty a powerhead that had a previous non-warranty failure, when it was rebuilt outside of Merc authorized service in somebody's home shop? I would have figured that once somebody else touched it that the warranty was kaput.
