1st- pushrod through rockerOriginally Posted by gmhdfan
2nd- bad ecm and bad long block rebuild by Merc/Marine Max resulting in a new "on the pallett motor being sent out
3rd holding up but had a heat exchanger and crossover give out.
All in all I was down 3 months this season because of these things, no compensation or even an apology from Merc, I really don't agree with the contention they have 'great" customer service, at least not in my case. i didn't get any service until they knew I was serious about suing them and Marine Max, it shouldn't have to come to that to get some decent service.
BTW, my ecm's checked out with no abuse and a handful of over revs, the 3rd motor is the only one that has been in ocean water.
Mercruiser 496HO Just not a good idea.
