LOL! I was just reading this and there's a few crazy ideas I think, and some reasonable ones.

And your Volvo guy, what's this, "up to 12 hours at 200 below max RPM" I thought he said you could run it all day long at any speed? And what happens after 12 hours?

It doesn't make much common sense to me that a diesel has to run flat out to last. The only thing that makes sense to me is simply running it long enough to warm up and dry out, get cooling and oil flow throughout. You can't stick to a regimen of diesel running guidelines like some of these posted, and own a sailboat.

Stuff like this seems far fetched to me, "There are factual reports of diesels that ran continuously as pumps on oil fields for 30 or 40 years straight, never shut down, oil changed on the fly, that showed virtually ZERO internal wear after a teardown."

Zero wear after 40 years? 349,440 Hrs? Three hundred forty nine thousand, four hundred and forty hours, and no wear?
How could that be possible?
