It is a perfectly fine engine....especially for the intended use of most of them. They are usually installed on boats that are not meant to plane....like maybe an Island Gypsy or a NT32. SO they live a very easy life in those types of installations and will last FOREVER! They have no charge air cooler(aftercooler) and no fuel cooler. Both of those things can make your life miserable and ruin your engine....although they do provide added power.
As far as what makes the a Diamond...I am not sure but I bet Ski can tell you. Edit: I guess Ski can't...hahaha. I did read somewhere that there is a difference or a reason they are called Diamonds. But when I heard it I remember thinking that it was marketing crap.
