Help a guy out here. I am looking at a MY with two of these engines and several people have said to walk away from any MY with them. I am told these are 480 H.P. Engines when built by DD and then J&T push them to the limits in boost and fuel injectors. The argument is when you push an engine that hard they have a short life span between major rebuilds. I am also told they are fuel hogs in order to get that power from them. The ones I am looking at have about 2700 hours on them since the last major and I've been told by more than one person they are running on borrowed time and I am looking at a $40K to $50K bill in the very near future. I won't be spending that as I will do the work myself (I am a mechanical engineer and can read the DD manuals) but still, its a lot of work and expense. I have a sea trial scheduled next week with a SAM surveyor. So, are these really "just don't buy them" engines or is there a lot of smoke being blown up my backside?
