Yes to say the least. The engine was completely gone through.
Yanmar isn’t the only manufacturer with a black Mark in in there history book. You can Google the class action suit and get different variations of how things where taken care of. Moving forward Mack Boring/Yanmar has been exceptional in taking care of customers. Let’s not keep beating a dead horse. Like you said 2003, 2004. No one is going to repower with a engine that is almost 20 years old.
